This 8 bit wide, active high strobe is active during the B2 PCM channel in ST-BUS mode. Forced to high impedance when LINEAR=1.Pin #Name DescriptionZL38010Data Sheet Functional DescriptionThe Quad-channel ADPCM Transcoder is a low power, CMOS device capable of four encode and four decode operations per frame. Four 64kbps channels (PCM octets) are compressed into four 32, 24 or 16kbps ADPCM channels (ADPCM words), and four 32, 24 or 16kbps ADPCM channels (ADPCM words) are expanded into four 64kbps PCM channels (PCM octets). The ADPCM transcoding algorithm utilized conforms to ITU-T recommendation G.726 (excluding 40kbps), and ANSI T1.303 - 1989. Switching on-the-fly between 32 and 24kbps transcoding is possible by toggling the appropriate mode select pins (supports T1 robbed-bit signalling). All functions supported by the device are pin selectable. The four encode functions comprise a common group controlled via Mode Select pins MS1, MS2 and MS3. Similarly, the four decode functions form a second group commonly controlled via Mode Select pins MS4, MS5 and MS6. All other pin controls are common to the entire transcoder.The device requires 6.5mWatts (MCLK= 4.096MHz) typically for four channel transcode operation. A minimum master clock frequency of 4.096MHz is required for the circuit to complete four encode channels and four decode channels per frame. For SSI operation a master clock frequency greater than 4.096MHz and asynchronous, relative to the 8kHz frame, is allowed.The PCM and ADPCM serial busses support both ST-BUS and Synchronous Serial Interface (SSI) operation. This allows serial data clock rates from 128kHz to 4096kHz, as well as compatibility with Zarlink’s standard Serial Telecom BUS (ST-BUS). For ST-BUS operation, on chip channel counters provide channel enable outputs as well as a 2048kHz bit clock output which may be used by down-stream devices utilizing the SSI bus interface.Linear coded PCM is also supported. In this mode the encoders compress, four 14-bit, two’s complement (S,S,S,12,...,1,0), uniform PCM channels into four 4, 3 or 2 bit ADPCM channels. Similarly, the decoder expands four 4, 3 or 2 bit ADPCM channels into four 16-bit, two’s complement (S,14,...,1,0), uniform PCM channels. The data rate for both ST-BUS and SSI operation in this mode is 2048 kbps.ZL38010Data Sheet Serial (AD)PCM Data I/OSerial data transfer to/from the Quad ADPCM transcoder is provided through one ADPCM and two PCM ports (ADPCMi, ADPCMo, PCMi1, PCMo1, PCMi2, PCMo2). Data is transferred through these ports according to either ST-BUS or SSI requirements. The device determines the mode of operation by monitoring the signal applied to the F0i pin. When a valid ST-BUS frame pulse (244nSec low going pulse) is applied to the F0i pin the transcoder will assume ST-BUS operation. If F0i is tied continuously to V SS the transcoder will assume SSI operation. Pin functionality in each of these modes is described in the following sub-sections.ST-BUS ModeDuring ST-BUS operation the C2o, EN1, EN2 and F0od outputs become active and all serial timing is derived from the MCLK (C4) and F0i inputs while the BCLK input is tied to V SS. (See Figures 7, 8 & 9.)Basic Rate “D” and “C” ChannelsIn ST-BUS mode, when ENB1 is brought low, transparent transport of the ST-BUS "Basic Rate D- and C-channels" is supported through the PCMi1 and PCMo1 pins. This allows a microprocessor controlled device, connected to the PCMi/o1 pins, to access the "D" and "C" channels of a transmission device connected to the ADPCMi/o pins. When ENB1 is brought high, the “D” and “C” channel outputs are tristated. Basic Rate “D” and “C” channels are not supported in LINEAR mode.(See Figure 7.)SSI ModeDuring SSI operation the BCLK, ENB1 and ENB2/F0od inputs become active. The C2o, EN1, and EN2 outputs are forced to a high-impedance state except during LINEAR operation during which the EN1 output remains active. (See Figures 4, 5 & 6.)The SSI port is a serial data interface, including data input and data output pins, a variable rate bit clock input and two input strobes providing enables for data transfers. There are three SSI I/O ports on the Quad ADPCM; the PCMi/o1 PCM port, the PCMi/o2 PCM port, and the ADPCMi/o port. The two PCM ports may transport 8-bit companded PCM or 16-bit linear PCM. The alignment of the channels is determined by the two input strobe signals ENB1 and ENB2/F0od. The bit clock (BCLK) and input strobes (ENB1 and ENB2/F0od) are common for all three of the serial I/O ports. BCLK can be any frequency between 128kHz and 4096kHz synchronized to the input strobes. BCLK may be discontinuous outside of the strobe boundaries except when LINEAR=1. In LINEAR mode, BCLK must be 2048kHz and continuous for 64 cycles after the ENB1 rising edge and for the duration of ENB2/F0od. Mode Select Operation (MS1, MS2, MS3, MS4, MS5, MS6)Mode Select pins MS1, MS2 and MS3 program different bit rate ADPCM coding, bypass, algorithmic reset and disable modes for all four encoder functions simultaneously. When 24kbps ADPCM mode is selected bit 4 is unused while in 16kbps ADPCM mode all ADPCM channels are packed contiguously into one 8-bit octet. Mode Select pins MS4, MS5 and MS6 operate in the same manner for the four decode functions. The mode selects must be set up according to the timing constraints illustrated in Figures 16 and 17.32 kbps ADPCM ModeIn 32kbps ADPCM mode, the 8-bit PCM octets of the B1, B2, B3 and B4 channels (PCMi1 and PCMi2) are compressed into four 4-bit ADPCM words on ADPCMo. Conversely, the 4-bit ADPCM words of the B1, B2, B3 and B4 channels from ADPCMi are expanded into four 8-bit PCM octets on PCMo1 and PCMo2. The 8-bit PCM octets (A-Law or µ-Law) are transferred most significant bit first starting with b7 and ending with b0. ADPCM words are transferred most significant bit first starting with I1 and ending with I4 (See Figures 4 & 7). Reference ITU-T G.726 for I-bit definitions.ZL38010Data Sheet24 kbps ADPCM ModeIn 24kbps mode PCM octets are transcoded into 3-bit words rather than the 4-bit words utilized in 32kbps ADPCM. This is useful in situations where lower bandwidth transmission is required. Dynamic operation of the mode select control pins will allow switching from 32kbps mode to 24kbps mode on a frame by frame basis. The 8 bit PCM octets (A-Law or µ-Law) are transferred most significant bit first starting with b7 and ending with b0. ADPCM words are transferred most significant bit first starting with I1 and ending with I3 (I4 becomes don’t care). (See Figures 4 & 7.)16 kbps ADPCM ModeWhen SEL is set to 0, the 8-bit PCM octets of the B1, B2, B3 and B4 channels (PCMi1 and PCMi2) are compressed into four 2-bit ADPCM words on ADPCMo during the ENB1 timeslot in SSI mode and during the B1 timeslot in ST-BUS mode. Similarly, the four 2-bit ADPCM words on ADPCMi are expanded into four 8-bit PCM octets (on PCMo1 and PCMo2) during the ENB1/B1 timeslot. (See Figures 4 & 7.)When SEL is set to 1, The same conversion takes place as described when SEL = 0 except that the ENB2/B2 timeslots are utilized.A-Law or µ-Law 8-bit PCM are received and transmitted most significant bit first starting with b7 and ending with b0. ADPCM data are most significant bit first starting with I1 and ending with I2.ADPCM BYPASS (32 and 24 kbps)In ADPCM bypass mode the B1 and B2 channel ADPCM words are bypassed (with a two-frame delay) to/from the ADPCM port and placed into the most significant nibbles of the PCM1/2 port octets. Note that the SEL pin performs no function for these two modes (See Figures 6 & 9). LINEAR, FORMAT and A/µ pins are ignored in bypass mode. In 32kbps ADPCM bypass mode, Bits 1 to 4 of the B1, B2, B3 and B4 channels from PCMi1 and PCMi2 are transparently passed, with a two frame delay, to the same channels on ADPCMo. In the same manner, the B1, B2, B3 and B4 channels from ADPCMi are transparently passed, with a two frame delay, to the same channels on PCMo1 and PCMo2 pins. Bits 5 to 8 are don’t care. This feature allows two voice terminals, which utilize ADPCM transcoding, to communicate through a system without incurring unnecessary transcode conversions. This arrangement allows byte-wide or nibble-wide transport through a switching matrix.24kbps ADPCM bypass mode is the same as 32 kbps mode bypass excepting that only bits 1 to 3 are bypassed and bits 4 to 8 are don’t care.ADPCM BYPASS (16 kbps)When SEL is set to 0, only bits 1 and 2 of the B1, B2, B3 and B4 PCM octets (on PCMi1 and PCMi2) are bypassed, with a two frame delay, to the same channels on ADPCMo during the ENB1 timeslot in SSI mode and during the B1 timeslot in ST-BUS mode. Similarly, the four 2-bit ADPCM words on ADPCMi are transparently bypassed, with a two frame delay, to PCMo1 and PCMo2 during the ENB1 or B1 timeslot. Bits 3-8 are don’t care. (See Figures 6 & 9.)When SEL is set to 1, the same bypass occurs as described when SEL = 0 except that the ENB2 or B2 timeslots are utilized.LINEAR, FORMAT and A/µ pins are ignored in bypass mode.ZL38010Data SheetPCM BYPASSWhen SEL is set to 0, the B1 and B2 PCM channels on PCMi1 are transparently passed, with a two-frame delay, to the same channels on the ADPCMo. Summarily, the two 8-bit words which are on ADPCMi are transparently passed, with a two-frame delay, to channels B1 and B2 of PCMo1 while PCMo2 is set to a high-impedance state.(See Figures 6 & 9.)When SEL is set to 1, the B3 and B4 channels on PCMi2 are transparently passed, with a two frame delay, to the same channels on ADPCMo. Similarly, the two 8-bit words which are on ADPCMi are transparently passed, with a two-frame delay, to channels B3 and B4 of PCMo2. In this case PCMo1 is always high-impedance if ENB1 = 0. If ENB1 = 1 during ST-BUS operation then the D and C channels are active on PCMo1.LINEAR, FORMAT and A/µ pins are ignored in bypass mode.Algorithm Reset ModeWhile an algorithmic reset is asserted the device will incrementally converge its internal variables to the 'Optional reset values' stated in G.726. Algorithmic reset requires that the master clock (MCLK) and frame pulse (ENB1/2 or F0i) remain active and that the reset condition be valid for at least four frames. Note that this is not a power down mode; see PWRDN for this function.ADPCMo & PCMo1/2 DisableWhen the encoders are programmed for ADPCMo disable (MS1 to MS3 set to 1) the ADPCMo output is set to a high impedance state and the internal encode function remains active. Therefore convergence is maintained. The decode processing function and data I/O remain active.When the decoders are programmed for PCMo1/2 disable (MS4 to MS6 set to 1) the PCMo1/2 outputs are high impedance during the B Channel timeslots and also, during ST-BUS operation, the D and C channel timeslots according to the state of ENB1. Therefore convergence is maintained. The encode processing function and data I/O remain active.Whenever any combination of the encoders or decoders are set to the disable mode the following outputs remain active. A) ST-BUS mode: ENB2/F0od, EN1, EN2 and C2o. Also the “D” and “C” channels from PCMo1 and ADPCMo remain active if ENB1 is set to 0. If ENB1 is brought high then PCMo1 and ADPCMo are fully tri-stated. B) SSI mode: When used in the 16-bit linear mode, only the EN1 output remains active. For complete chip power down see PWRDN.ZL38010Data Sheet Other Pin Controls16 Bit Linear PCMSetting the LINEAR pin to logic one causes the device to change to 16-bit linear (uniform) PCM transmission on the PCMi/o1 and PCMi/o2 ports. The data rate for both ST-BUS and SSI operation in this mode is 2048 kbps and all decode and encode functions are affected by this pin. In SSI mode, the input channel strobes ENB1 and ENB2/F0od remain active for 8 cycles of BCLK for an ADPCM transfer. The EN1 output is high for one BCLK period at the end of the frame (i.e., during the 256th BCLK period). In ST-BUS mode, the output strobes EN1 and ENB2/F0od are adjusted to accommodate the required PCM I/O streams. The EN1 output becomes a single bit high true pulse during the last clock period of the frame (i.e., the 256th bit period) while ENB2/F0od becomes a delayed, low true frame-pulse (F0od) output occurring during the 64th bit period after the EN1 rising edge.Linear PCM on PCMi1 and PCMi2, are received as 14-bit, two’s complement data with three bits of sign extension in the most significant positions (i.e., S,S,S,12,...1,0) for a total of 16 bits. The linear PCM data transmitted from PCMo1 and PCmo2 are 16-bit, two’s complement data with one sign bit in the most significant position (i.e., S,14,13,...1,0)32 and 24 kbps ADPCM modeIn 32kbps and 24kbps linear mode, the 16-bit uniform PCM dual-octets of the B1, B2, B3 and B4 channels (from PCMi1 and PCMi2) are compressed into four 4-bit words on ADPCMo. The four 4-bit ADPCM words of the B1, B2, B3 and B4 channels from ADPCMi are expanded into four 16-bit uniform PCM dual-octets on PCMo1 and PCMo2. 16-bit uniform PCM are received and transmitted most significant bit first starting with b15 and ending with b0. ADPCM data are transferred most significant bit first starting with I1 and ending with I4 for 32kbps and ending with I3 for 24kbps operation (i.e., I4 is don’t care).(See Figures 5 & 8.)16 kbps ADPCM modeWhen SEL is set to 0, the four, 2-bit ADPCM words are transmitted/received on ADPCMo/i during the ENB1 time-slot in SSI mode and during the B1 timeslot in ST-BUS mode. When SEL is set to 1, the four, 2-bit ADPCM words are transmitted/received on ADPCMo/i during the ENB2 timeslot in SSI mode and during the B2 timeslot in ST-BUS mode. (See Figures 5 & 8.)PCM Law Control (A/µ, FORMAT)The PCM companding/coding law invoked by the transcoder is controlled via the A/µ and FORMAT pins. ITU-T G.711 companding curves, µ-Law and A-Law, are selected by the A/µ pin (0=µ-Law; 1=A-Law). Per sample, digital code assignment can conform to ITU-T G.711 (when FORMAT=1) or to Sign-Magnitude coding (when FORMAT=0). Table 1 illustrates these choices.ZL38010Data SheetTable 1 - Companded PCMPower DownSetting the PWRDN pin low will asynchronously cause all internal operation to halt and the device to go to a power down condition where no internal clocks are running. Output pins C2o, EN1, EN2, PCMo1, PCMo2 and ADPCMo and I/O pin F0od/ENB2 are forced to a high-impedance state. Following the reset (i.e., PWRDN pin brought high)and assuming that clocks are applied to the MCLK and BCLK pins, the internal clocks will still not begin to operate until the first frame alignment is detected on the ENB1 pin for SSI mode or on the F0i pin for ST-BUS mode. The C2o clock and EN1, EN2 pins will not start operation until a valid frame pulse is applied to the F0i pin. If the F0i pin remains low for longer than 2 cycles of MCLK then the C2o pin will top toggling and will stay low. If the F0i pin is held high then the C2o pin will continue to operate. In ST-BUS mode the EN1 and EN2 pins will stop toggling if the frame pulse (F0i) is not applied every frame.Master Clock (MCLK)A minimum 4096kHz master clock is required for execution of the transcoding algorithm. The algorithm requires 512 cycles of MCLK during one frame for proper operation. For SSI operation this input, at the MCLK pin, may be asynchronous with the 8kHz frame provided that the lowest frequency and deviation due to clock jitter still meets the strobe period requirement of a minimum of 512 t C4P - 25%t C4P (see Figure 3). For example, a system producing large jitter values can be accommodated by running an over-speed MCLK that will ensure a minimum 512 MCLK cycles per frame is obtained. The minimum MCLK period is 61nSec, which translates to a maximum frequency of 16.384MHz. Extra MCLK cycles (>512/frame) are acceptable since the transcoder is aligned by the appropriate strobe signals each frame.Figure 3 - MCLK Minimum RequirementFORMAT01PCM CodeSign-Magnitude A/µ = 0 or 1ITU-T (G.711)(A/µ = 0)(A/µ = 1)+ Full Scale 1111 11111000 00001010 1010+ Zero 1000 00001111 11111101 0101- Zero 0000 00000111 11110101 0101- Full Scale0111 11110000 00000010 1010ENB1MCLK512 t C4P - 25%t C4P MinimumZL38010Data Sheet Bit Clock (BCLK)For SSI operation the bit rate, for both ADPCM and PCM ports, is determined by the clock input at BCLK. BCLK must be eight periods in duration and synchronous with the 8kHz frame inputs at ENB1 and ENB2. Data is sampled at PCMi1/2 and at ADPCMi concurrent with the falling edge of BCLK. Data is available at PCMo1/2 and ADPCMo concurrent with the rising edge of BCLK. BCLK may be any rate between 128kHz and 4096kHz. For ST-BUS operation BCLK is ignored (tie to V SS) and the bit rate is internally set to 2048kbps.Figure 4 - SSI 8-Bit Companded PCM Relative TimingZL38010Data SheetFigure 5 - SSI 16-Bit Linear PCM Relative TimingZL38010Data SheetFigure 6 - SSI PCM and ADPCM Bypass Relative TimingZL38010Data SheetFigure 7 - ST-BUS 8-Bit Companded PCM Relative TimingZL38010Data SheetFigure 8 - ST-BUS 16-Bit Linear PCM Relative TimingZL38010Data SheetFigure 9 - ST-BUS PCM and ADPCM Bypass Relative TimingZL38010Data Sheet Processing Delay Through the DeviceIn order to accommodate variable rate PCM and ADPCM interfaces, the serial input and output streams require a complete frame to load internal shift registers. Internal frame alignment of the encoding/decoding functions are taken from either of the F0i or ENB1 & ENB2 input strobes depending upon the device operating mode (i.e., ST-BUS or SSI). The encoding/decoding of all channels then takes one frame to complete before the output buffers are loaded. This results in a two frame transcoding delay. The two frame delay also applies to the D and C channels and to the PCM and ADPCM bypass functions.(See Figure 10.)Note: When changing the relative positions of the ENB1 and ENB2 strobes, precaution must be taken to ensure that two conditions are met. They are:1.There must be at least 512 master clock cycles between consecutive rising edges of ENB1. This condition alsoholds true for ENB2.2.The ENB1 strobe must alternate with the ENB2 strobe.Violation of these requirements may cause noise on the output channels.Figure 10 - Data ThroughputApplicationsFigure 11 depicts an ISDN line card utilizing a ’U’ interface transceiver and ZL38010 ADPCM transcoder.

A functional block diagram is shown in Figure 1.This device is ideally suited for designs that require both a transmit timing path (backplane to PHY) and a receive timing path (PHY to backplane). Each path is controlled with separate DPLLs (Tx DPLL, Rx DPLL) which are both independently configurable through the serial interface (SPI or I2C). A typical application of the ZL30131 is shown in Figure 2. In this application, the ZL30131 translates the 19.44MHz clock from the telecom rate backplane (system timing bus), translates the frequency to 622.08MHz or 156.25MHz for the PHY Tx clock, and filters the jitter to ensure compliance with the related standards. A programmable synthesizer (P0) provides synchronous PDH clocks with multiples of 8kHz for generating PDH interface clocks. On the receive path, the Rx DPLL and the P1 synthesizer translate the line recovered clock (8kHz or 25MHz) from the PHY to the 19.44MHz telecom backplane (line recovered timing) for the central timing cards. The ZL30131 allows easy integration of Ethernet line rates with today’s telecom backplanes.Figure 2 - Typical Application of the ZL30131Information relating to products and services furnished herein by Zarlink Semiconductor Inc. or its subsidiaries (collectively “Zarlink”) is believed to be reliable.However, Zarlink assumes no liability for errors that may appear in this publication, or for liability otherwise arising from the application or use of any such information, product or service or for any infringement of patents or other intellectual property rights owned by third parties which may result from such application or use.

• Handles up to -6 dB acoustic echo return loss
• 127 ms acoustic echo canceller
• Provides up to 12 dB of Noise Reduction
• Operate in two modes, Dual Analog mode and single Analog mode (other port is digital PCM)
The AEC uses an advanced adaptive filter algorithm that is double-talk stable, allowing convergence even while both parties are talking. This algorithm continually tracks changes in the echo path, regardless of double-talk, as long as a reference signal is available for the echo canceller.
• PCM Data Formats in single Port mode- 16-bit Linear, companded ITU-T A-law or U-law
• Advanced NLP design - full duplex speech with no switched loss on audio paths

2.0 Acoustic Echo Canceller (AEC) Description
The AEC section is comprised of an acoustic echo canceller, noise reduction and the operational control functions for operation. The AEC guarantees clear signal transmission in both transmit and receive audio path directions ensuring reliable voice communication even when low level signals are provided. The AEC does not use variable attenuators during double-talk or single-talk periods of speech, as do many other acoustic echo cancellers for speakerphones. Instead, the AEC provides high performance full-duplex operation similar to network echo cancellers. This results in users experiencing clear speech and uninterrupted background signals during the conversation and prevents subjective sound quality problems associated with “noise gating” or “noise contrasting”.
Applications
• Hands-free car kits • Full duplex speaker-phone for digital telephone • Echo cancellation for video conferences • Intercom Systems • Security Systems

1.0 Functional Description
The ZL38003 is an Acoustic Echo Canceller (AEC) with dual codec as shown in Figure 2. The ZL38003 provides 127 ms of acoustic echo cancellation, which makes it ideal for hand free car kits, and speaker phones designs. Each of the codecs in the dual codec can be connected to 1 of 4 four analog ports through a cross point switch. Also, the network side can be routed to a digital PCM interface that input/outputs either linear 2's complement or A-/mu law commanded PCM data.
