AD9854芯片引脚功能介绍
I 和 Q DACs 的通用连接引脚。用来设置满比例输出电流。 此引脚为 REFCLK Multiplier’s PLL 回路滤波器的外部零补偿网络提供连 接。 DIFF CLK ENABLE 差分 REFCLK 使能。 互补（180 度反相）差分时钟信号。 单端（CMOS 逻辑电平要求）参考时钟输入或两个差分时钟中的一个信号。 串行编程模式（逻辑低）和并行编程模式（逻辑高）之间的选择。 为用户编程来初始化串行/并行编程总线，用表 IV 中的默认值来设置编程 寄存器为“do-nothing”状态。激活时为逻辑高。为了正确运行必须在启 动时就定义此引脚。
经过反复查阅资料，我决定使用并行编程模式！下面一步步讲明设计的思路： （1） 先解决 AD9854 稳定供电的问题 参考 AD9854 技术文档中提供的评估板的原理图，将接 DVDD 的与接 AVDD 相连直接 接到 3.3V 直流电源，并且在端口并上一个 10 F 的极性电容和 7 个 0.1uF 的非极性电容用来 提高电压的稳定性。 （2） AD9854 的参考时钟设计——外部晶振 参考如下三段资料： （一） AD9854AST 芯片的内部时钟在使用时是否一定要达到 200MHZ？我要在 000 模式 下输出 1MHZ 的正弦波请问用下面哪一种方法合适？①用 24MHZ 的外部参考时钟做系统时钟 ②用 24MHZ 的外部参考时钟将它放大 8 倍达 192MHZ 而不是 200MHZ，然后在用公式下算出 1MHZ。 经过我们这一小组讨论和 ANALOG 公司的帮忙知道使我明白 200MHZ 是系统的最大频率， 可以不需要倍频直接将 24MHZ 参考时钟作为系统时钟。 在系统中最好少用 PLL 倍频电路， 因 为如果倍频 N 倍的话，那么它的相噪和杂散将恶化 20lgN dB，所以直接用 24MHZ 做系统时 钟比较好。 （二）AD9854 的地址端数据端用的是并口写入的方式，串口通信中要考虑时序问题， 那么在并口的方式下还用不用考虑时序的问题？ 在反复翻阅资料和讨论下， 我们认为在并口情况下也需要考虑时序问题。 本设计中如果 我们将 MSP430F149 系统时钟周期设定为 32768HZ ， AD9854 用 24MHZ 做系统时钟，即

The resultant SNR was known to be limited by the jitter of the clock, not by the noise on the AIN signal. From this SNR value, the jitter affecting the measurement can be back calculated. 2Driving the REFIN input buffer. The crystal oscillator section of this input stage performs up to only 30 MHz. 3The charge pump output compliance range is functionally 0.2 V to (CP_VDD − 0.2 V).

ISM Band Modulator (LO & Baseband Generation)APPLICATION CIRCUIT DESCRIPTIONSDual Clock ConfigurationIn this loop, M = 1, N = 16, and R = 4. The DDS (direct digital synthesizer) tuning word is also equal to ¼, so that the frequency of CLOCK1’ equals the frequency of CLOCK 1. Phase adjustments in the DDS provide 14-bit programmable rising edge delay capability of CLOCK1’ with respect to CLOCK1 (see Figure 32).Optical Networking ClockThis is the AD9540 configured as an optical networking clock. The loop can be used to generate a 622 MHz clock for OC12. The DDS can be programmed to output 8 kHz to serve as a base reference for other circuits in the subsystem (see Figure 33). Fractional-Divider Loop This loop offers the precise frequency division (48-bit) of the DDS in the feedback path as well as the frequency sweeping capability of the DDS. Programming the DDS to sweep from 24 MHz to 25 MHz sweeps the output of the VCO from 2.7 GHz to 2.6 GHz. The reference in this case is a simple crystal (see Figure 34). Direct UpconversionThe AD9540 is configured to use the DDS as a precision reference to the PLL. Since the VCO is <655 MHz, it can be fed straight into the phase frequency detector feedback.LO and Baseband Modulation GenerationUsing the AD9540 PLL section to generate LO and the DDS portion to generate a modulated baseband, this circuit uses an external mixer to perform some simple modulation at RF ISM band frequencies (see Figure 36).THEORY OF OPERATIONPLL CIRCUITRYThe AD9540 includes an RF divider (divide-by-R), a 48-bit DDS core, a 14-bit programmable delay adjustment, a 10-bit DAC (digital-to-analog converter), a phase frequency detector, and a programmable output current charge pump. Incorporat-ing these blocks together, users can generate many usefulcircuits for clock synthesis. A few simple examples are shown in the Typical Performance Characteristics section.The RF divider accepts differential or single-ended signals up to 2.7 GHz on the CLK1 input pin. The RF divider also supplies the SYSCLK input to the DDS. Because the DDS operates only up to 400 MSPS, device function requires that for any CLK1 signal >400 MHz, the RF divider must be engaged. The RF divider can be programmed to take values of 1, 2, 4, or 8. The ratio for the divider is programmed in the control register. The output of the divider can be routed to the input of the on-chip CML driver. For lower frequency input signals, it is possible to use the divider to divide the input signal to the CML driver and to use the undivided input of the divider as the SYSCLK input to the DDS, or vice versa. In all cases, the SYSCLK to the DDS should not exceed 400 MSPS.The on-chip phase frequency detector has two differential inputs, REFIN (the reference input) and CLK2 (the feedback or oscillator input). These differential inputs can be driven by single-ended signals. When doing so, tie the unused input through a 100 pF capacitor to the analog supply (AVDD). The maximum speed of the phase frequency detector inputs is200 MHz. Each of the inputs has a buffer and a divider (÷M on REFIN and ÷N on CLK2) that operates up to 655 MHz. If the signal exceeds 200 MHz, the divider must be used. The dividers are programmed through the control registers and take any integer value between 1 and 16.The REFIN input also has the option of engaging an in-line oscillator circuit. Engaging this circuit means that the REFIN input can be driven with a crystal in the range of 20 MHz ≤ REFIN ≤ 30 MHz.The charge pump outputs a current in response to an error signal generated in the phase frequency detector. The output current is programmed through by placing a resistor (CP_R SET ) from the CP_RSET pin to ground. The value is dictated bySETCP_R CP_IOUT 1.55=This sets the charge pump reference output current. Also, a programmable scaler multiplies this base value by any integer from 1 to 8, programmable through the CP current scale bits in the Control Function Register 2, CFR2[2:0].CML DRIVERAn on-chip current mode logic (CML) driver is also included. This CML driver generates very low jitter clock edges. The outputs of the CML driver are current outputs that drive PECL levels when terminated into a 100 Ω load. The continuous output current of the driver is programmed by attaching aresistor from the DRV_RSET pin to ground (nominally 4.02 kΩ for a continuous current of 7.2 mA). An optional on-chip current programming resistor is enabled by setting a bit in the control register. The rising edge and falling edge slew rates are independently programmable to help control overshoot and ringing by the application of surge current during rising edge and falling edge transitions (see Figure 37). There is a default surge current of 7.6 mA on the rising edge and of 4.05 mA on the falling edge. Bits in the control register enable additional rising edge and falling edge surge current, as well as disable the default surge current (see the Control Register Bit Descriptions section for details). The CML driver can be driven by: • RF divider input (CLK1 directly to the CML driver) • RF divider output •CLK2 input04947-017Figure 37. Rising Edge and Falling Edge Surge Current Out of the CML Clock Driver, as Opposed to the Steady State Continuous CurrentDDS AND DACFinally, the amplitude words are piped to a 10-bit DAC. Because the DAC is a sampled data system, the output is a reconstructed sine wave that needs to be filtered to take high frequency images out of the spectrum. The DAC is a current steering DAC that is AVDD referenced. To get a measurable voltage output, the DAC outputs must be terminated through a load resistor to AVDD, typically 50 Ω. At positive full scale, IOUT sinks no current and the voltage drop across the load resistor is 0. However, the IOUT output sinks the programmed full-scale output current of the DAC, causing the maximum output voltage drop across the load resistor. At negative full-scale, the situation is reversed and IOUT sinks the full-scale current (and generates the maximum drop across the load resistor), while IOUT sinks no current (and generates no voltage drop). At midscale, the outputs sink equal amounts of current, generating equal voltage drops.The precision frequency division within the device isaccomplished using DDS technology. The DDS can control the digital phase relationships by clocking a 48-bit accumulator. The incremental value loaded into the accumulator, known as the frequency tuning word, controls the overflow rate of the accumulator. Similar to a sine wave completing a 2π radian revolution, the overflow of the accumulator is cyclical in nature and generates a fundamental frequency according to482)(s o f FTW f ×=}2W {047≤≤FT The instantaneous phase of the sine wave is therefore the output of the phase accumulator block. This signal can be phase-offset by programming an additive digital phase that is added to each phase sample coming out of the accumulator.These instantaneous phase values are then piped through a phase-to-amplitude conversion (sometimes called an angle-to-amplitude conversion or AAC) block. This algorithm follows a COS(x) relationship, where x is the phase coming out of the phase offset block, normalized to 2π.。
真值有效值转换芯片AD637
真值有效值转换芯片AD637简介赵亮1 器件用途及特点AD637是AD公司生产的真有效值-直流转换芯片，它的功能是把外部输入的交流信号有效值变成直流信号输出，可以计算各种复杂波形的真有效值。
可测量的输入信号有效值可高达7V,对于1vRMS的信号，它的3dB带宽为8MHz,并且可以对输入信号的电平以dB形式指示，当输入电压为100mV 时，带宽标值为600kHz；输入电压为2V时，带宽标称值为8MHz。
另外，AD637通过片选（CS）管脚作用，可以使静态电流从2.2mA降至350µA。
因此，在数据采集和仪器仪表等场合，有很广泛的应用。
2 管脚功能描述AD637的管脚图如图1所示，对应的管脚功能如表一。

输入缓冲和输出偏移接到内部的模拟公共端，一起接地；dB输出端悬空；输出缓冲悬空；CS通过一个外部的上拉电阻接Vs，降低系统在静态时的工作电流；外部的输入信号如果是交流信号，需要在输入端串接一个无极性的耦合电容；电容Cav作用是调整输出的直流信号纹波大小。
图2 AD637典型电路4 注意事项经实际测量，AD637在输入信号为2MHz以下、有效值为0.7 ～ 7V范围内能保证测量误差≤± 0.2%+0.5mV。
当被测信号的有效值远小于1V时，会出现较大的测量误差，所以当被测信号幅值较小时，须在前级对被测信号进行放大，以保证测量精度。
