DIN 934 与4032的区别和联系

DIN 934 与4032的区别和联系DIN 934 ：DIN 934 是螺帽的一个尺寸标准，它是德国起先的标准，如果要检测螺帽的机械性能是否合格，就要查阅DIN 267-4标准，它详细说明了螺帽的检测方法和检测数据，在这个标准中它包括4、5、6、8、10、12等六个等级。

螺帽的保载恒定不变，分别为400MPa、500MPa、600MPa、800MPa、1000MPa、1200MPa。

ISO 4032：但随着科学的进步和人们对质量意识的提高，发现此标准的规定给质量安全带来很大的隐患。

因为人们总是希望在螺栓和螺帽的配合过程中，如果发生质量事故，他们总是渴望螺栓首先失效，这样可以观察出来防患未然，如果螺帽发生失效，这事故是突然的，所以欧盟和ISO国际组织经过修订，产生了新的标准即ISO 4032标准。

该标准的厚度有所增加，所以检测标准便采用了ISO898-2，此机械性能标准规定螺母的保载随规格的递增而递增，如8级螺帽由840MPa逐渐递增到920MPa。

本来打算从DIN 267-4中删除粗牙螺母强度等级的以往规定，由DIN ISO 898-2代替。

但因为由于后者标准不仅有较高的保证载荷，而且厚度也发生了变化，同时也考虑到先行的、而且在短时间内还不能废除DIN 934以及现有的无数技术文件和图样，这样DIN 267-4还需要保留，但必须和DIN ISO 898-2相区分，所以在以DIN267-4检验标准检验的螺母的性能等级标准的标记加两条竖线，例如|8|，以防止混淆。

我们认为，DIN 934没有对应的所谓“真”8级和“假”8级之分，只是对标准的不同称呼罢了。

在新的标准中，对边尺寸除了M10、M12、M14、M22的变化以外，其他没有改变；但是螺帽的厚度却都变厚了，所以用DIN 934的尺寸标准，EN 20898-2机械性能的标准来检验螺母是及其不科学的，也不一定都能得到要求。

综上所述DIN 934只能和DIN 267-4对应；DIN EN ISO 4032只能和EN 20898-2对应。

MAX9492中文资料

General DescriptionThe MAX9492 frequency synthesizer is designed to generate multiple clocks for clock distribution in net-work routers or switches. The device provides a total of six buffered clock outputs (CLK1 to CLK6). CLK1 is the buffered output of the reference clock. CLK2 through CLK6 are independently programmable to generate eight different frequencies based on a 25MHz input crystal: 133, 125, 83, 66, 62.5, 50, 33, and 25MHz. All the outputs are LVCMOS single-ended signals. Either a 25MHz crystal or an external clock can serve as the input reference clock. The MAX9492 incorporates two phase-locked loops (PLLs) with two internal loop filters.Select the MAX9492’s output clock frequency by pro-gramming on-chip registers through the MAX9492’s I 2C* interface. The device also features spread-spec-trum capability to reduce electromagnetic interference (EMI). This technique allows spreading the fundamental energy over a wider frequency range, hence reducing the respective energy amplitude. The output frequency spectrum is downspread by -1.25% or -2.5%.The MAX9492 operates from a 3.3V supply and is guar-anteed over the extended temperature range (-40°C to +85°C). The device is available in a space-saving, 20-pin, TQFN, 5mm x 5mm package.ApplicationsNetwork RoutersTelecom/Networking EquipmentStorage Area Networks/Network Attached StorageFeatureso Five LVCMOS Outputs with Independent Frequency Selections o One Buffered Reference Clock Outputo Eight Selectable Frequencies: 133, 125, 83, 66,62.5, 50, 33, and 25MHz o Crystal or an Input-Clock-Based Clock Reference o Output Frequency Programmed Through I 2C Interface o 0, -1.25%, or -2.5% Selectable Downspreading Rate o Low Output Period Jitter(Without Spread Spectrum) < 10ps RMS o <220ps Output-to-Output Skewo Available in 20-Lead, 5mm x 5mm, TQFN Package o +3.3V Supplyo -40°C to +85°C Extended Temperature RangeMAX9492Multiple-Output Clock Generatorwith Spread Spectrum________________________________________________________________Maxim Integrated Products 1Ordering Information19-3683; Rev 0; 5/05For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Typical Operating Circuit and Pin Configuration appear atend of data sheet.*Purchase of I 2C components from Maxim Integrated Products, Inc., or one of its sublicensed Associated Companies, conveys a license under the Philips I 2C Patent Rights to use these components in an I 2C system, provided that the system conforms to the I 2C Standard Specification as defined by Philips.M A X 9492Multiple-Output Clock Generator with Spread Spectrum 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSDC ELECTRICAL CHARACTERISTICSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

The device provides a total of six buffered clock outputs (CLK1 to CLK6). CLK1 is the buffered output of the reference clock. CLK2 through CLK6 are independently programmable to generate eight different frequencies based on a 25MHz input crystal:133, 125, 83, 66, 62.5, 50, 33, and 25MHz. All the outputs are LVCMOS single-ended signals.Select the MAX9492’s output frequency by program-ming on-chip registers through the I 2C interface. The MAX9492 also features spread-spectrum capability to reduce EMI. Output frequency spectrum can be down-spread by -2.5% or -1.25%. The 25MHz reference comes from either a crystal or an external clock. The MAX9492 incorporates two PLLs with two internal loop filters. The MAX9492 operates from a 3.3V supply.Reference Frequency InputThe MAX9492 requires a reference frequency. The ref-erence can be a 25MHz crystal or an external clock signal. If using a 25MHz crystal, connect it across X1and X2, and connect loading capacitors from X1 and X2 to G ND (refer to the crystal manufacturer ’s specifi-cation). If using an external clock, connect the signal to X1 and leave X2 floating.Power-Up StateAt power-up, the CLK1 output is enabled and free run-ning, the CLK2 to CLK4 outputs are set at 33.3MHz,and the other CLK outputs are disabled at logic-low.The output states can be overridden by writing to the registers through the I 2C interface.Serial InterfaceThe MAX9492 is programmed through its I 2C serial interface. This interface has a clock, SCL, and a bidi-rectional data line, SDA. In an I 2C system, a master,typically a microcontroller, initiates all data transfers to and from slave devices, and generates the clock to synchronize the data transfers.The MAX9492 operates as a slave device. The timing of the SDA and SCL signals is detailed in Figure 1. SDA operates as both an input and an open-drain output. A pullup resistor, typically 4.7k Ω, is required on SDA. SCL operates only as an input. A pullup resistor, typically 4.7k Ω, is required on SCL.START and STOP ConditionsA master signals the beginning of a transmission with a START condition by transitioning SDA from high to low while SCL is high (Figure 2). When communication is complete, a master issues a STOP condition by transi-tioning SDA from low to high while SCL is high. The bus is then free for another transmission.Figure 1. Serial-Interface Timing DiagramM A X 9492Multiple-Output Clock Generator with Spread Spectrum 8_______________________________________________________________________________________Bit TransferOne data bit is transferred during each SCL clock cycle. SDA must remain stable during the high period of SCL, as changes in SDA while SCL is high are START and STOP control signals. Idle the interface by pulling both SDA and SCL high.After 8 bits are transferred, the receiving device gener-ates an acknowledge signal by pulling SDA low for the entire duration of the 9th clock pulse. If the receiving device does not pull SDA low, a not acknowledge is indicated (Figure 2).Device AddressThe MAX9492 features a 7-bit device address, config-ured by the two three-level address inputs, SA1 and SA0. To select the device address, connect SA1 and SA0 to V DD , G ND, or leave floating, as indicated in Table 1. The MAX9492 has nine possible addresses,allowing up to nine MAX9492 devices to share the same interface bus.Writing to the MAX9492Writing to the MAX9492 begins with a START condition (Figure 3). Following the START condition, each pulse on SCL transfers 1 bit of data. The first 7 bits comprise the device address (see the Device Ad d ress section).The 8th bit is low to indicate a write operation. An acknowledge bit is then generated by the MAX9492,signaling that it recognizes its address. The next 8 bits form the register address byte (Table 2) and determine which control register receives the following data byte.The MAX9492 then generates another acknowledge bit.The data byte is then written into the addressed register of the MAX9492. An acknowledge bit by the MAX9492followed by a required STOP condition by the master completes the communication. To write to the device again, the entire write procedure is repeated; I 2C burst-write mode is not supported by the MAX9492.Figure 2. I 2C Address and AcknowledgeMAX9492Multiple-Output Clock Generatorwith Spread Spectrum_______________________________________________________________________________________9Reading from the MAX9492Reading from the MAX9492 registers begins with a START condition and a device address with the write bit set low, then the register address that is to be read, fol-lowed by a repeated START condition and a device address with the write bit set high, and finally the data are shifted out (Figure 3). Following a START condition,the first 7 bits comprise the device address. The 8th bit is low to indicate a write operation (to write in the follow-ing register address). An acknowledge bit is then gener-ated by the MAX9492, signaling that it recognizes its address. The next 8 bits form the register address, indi-cating the location of the data to be read, followed by another acknowledge, again generated by the MAX9492. The master then produces a repeated START condition and readdresess the device, with the R/W bit high to indicate a read operation (Figure 3). The MAX9492 generates an acknowledge bit, signaling that it recognizes its address. The data byte is then clocked out of the MAX9492. A final not-acknowledge bit, gener-ated by the master (not required), and a STOP condition,also generated by the master, complete the communica-tion. To read from the device again, the entire read pro-cedure is repeated; I 2C burst-read mode is not supported by the MAX9492.Device Control RegistersThe MAX9492 has eight control registers. The register addresses and functions are shown in Table 2. The first seven registers are used to set the six outputs, with register 0x00 controlling all outputs simultaneously, and the rest are mapped to individual outputs. All other addresses are reserved and are not to be used.Figure 3. I 2C Interface Data StructurePin ConfigurationTypical Operating CircuitSetting the Clock FrequenciesEach CLK_ output has an associated control register.The contents of the registers determine the frequencies of their associated outputs. Table 3 provides the fre-quency mapping for the registers. CLK1 only responds to the 25MHz and high-impedance settings in Table 3.For example, writing 03h to the CLK1 control register does not change CLK1’s output frequency to 133.3MHz. The CLK1 output continues to output a buffered reference clock signal.Spread-Spectrum ControlThe MAX9492 features spread-spectrum output struc-tures to spread radiated emissions over the frequency band. A programmable triangle-wave generator injects an offset element into the master oscillator to dither its output by -1.25% or -2.5%. The dither is controlled by the SSC input. When SSC is low, spread spectrum is disabled. When SSC is floating, spread spectrum is set to -1.25%. When SSC is high, spread spectrum is set to -2.5%.Power SupplyThe MAX9492 uses a 3.0V to 3.6V power supply con-nected to V DD , and 3.0V to 3.6V connected to V DDA .Bypass V DDA and V DD at the device with a 0.1µF capacitor. Additionally, use bulk bypass capacitors of 10µF where power enters the circuit board.Applications InformationBoard Layout ConsiderationsAs with all high-frequency devices, board layout is criti-cal to proper operation. Place the crystal as close as possible to X1 and X2, and minimize parasitic capaci-tance around the crystal leads. Ensure that the exposed pad makes good contact with GND.Chip InformationPROCESS: BiCMOSM A X 9492Multiple-Output Clock Generator with Spread Spectrum 10MAX9492Multiple-Output Clock Generator with Spread SpectrumMaxim cannot assume responsibility for use of any circuitry other than circuitry entirely embod ied in a Maxim prod uct.

The device is optimized for use in many industrial and commercial applica-tions where low-power and low-voltage operations are essential. The AT93C46D is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Thin mini-MAP (MLP 2x3), 8-lead TSSOP, and 8-lead dBGA2 packages.The AT93C46D is enabled through the Chip Select pin (CS) and accessed via a three-wire serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK). Upon receiving a Read instruction at DI, the address is decoded and the data is clocked out serially on the DO pin. The Write cycle is completely self-timed,and no separate Erase cycle is required before Write. The Write cycle is only enabled when the part is in the Erase/Write Enable state. When CS is brought high following the initiation of a Write cycle, the DO pin outputs the Ready/Busy status of the part.The AT93C46D is available in 1.8 (1.8V to 5.5V) version.

Device operation is controlled by seven instructions issued by the host processor. A valid instruction starts with a rising edge of CS and consists of a start bit (logic “1”) followed by the appropriate op code and the desired memory address location.READ (READ): The Read (READ) instruction contains the address code for the memory loca-tion to be read. After the instruction and address are decoded, data from the selected memory location is available at the serial output pin DO. Output data changes are synchronized with the rising edges of serial clock SK. It should be noted that a dummy bit (logic “0”) precedes the 8- or 16-bit data output string.ERASE/WRITE ENABLE (EWEN): To assure data integrity, the part automatically goes into the Erase/Write Disable (EWDS) state when power is first applied. An Erase/Write Enable (EWEN)instruction must be executed first before any programming instructions can be carried out.Please note that once in the EWEN state, programming remains enabled until an EWDS instruc-tion is executed or V CC power is removed from the part.ERASE (ERASE): The Erase (ERASE) instruction programs all bits in the specified memory location to the logical “1” state. The self-timed erase cycle starts once the Erase instruction and address are decoded. The DO pin outputs the Ready/Busy status of the part if CS is brought high after being kept low for a minimum of 250 ns (t CS ). A logic “1” at pin DO indicates that the selected memory location has been erased and the part is ready for another instruction.WRITE (WRITE): The Write (WRITE) instruction contains the 8 or 16 bits of data to be written into the specified memory location. The self-timed programming cycle t WP starts after the last bit of data is received at serial data input pin DI. The DO pin outputs the Read/Busy status of the part if CS is brought high after being kept low for a minimum of 250 ns (t CS ). A logic “0” at DO indicates that programming is still in progress. A logic “1” indicates that the memory location at the specified address has been written with the data pattern contained in the instruction and theTable 1-4.Instruction Set for the AT93C46DInstruction SB Op Code Address DataCommentsx 8x 16x 8x 16READ 110A 6 – A 0A 5 – A 0Reads data stored in memory, at specified addressEWEN 10011XXXXX 11XXXX Write enable must precede all programming modesERASE 111A 6 – A 0A 5 – A 0Erases memory location A n – A 0WRITE 101A 6 – A 0A 5 – A 0D 7 – D 0D 15 – D 0Writes memory location A n – A 0ERAL 10010XXXXX 10XXXX Erases all memory locations.

A Ready/Busy status cannot be obtained if the CS is brought high after the end of the self-timed programming cycle tWP .ERASE ALL (ERAL): The Erase All (ERAL) instruction programs every bit in the memory array to the logic “1” state and is primarily used for testing purposes. The DO pin outputs the Ready/Busy status of the part if CS is brought high after being kept low for a minimum of 250 ns (t CS ). The ERAL instruction is valid only at V CC = 5.0V ± 10%.WRITE ALL (WRAL): The Write All (WRAL) instruction programs all memory locations with the data patterns specified in the instruction. The DO pin outputs the Ready/Busy status of the part if CS is brought high after being kept low for a minimum of 250 ns (t CS ). The WRAL instruction is valid only at V CC = 5.0V ± 10%.ERASE/WRITE DISABLE (EWDS): To protect against accidental data disturb, the Erase/Write Disable (EWDS) instruction disables all programming modes and should be executed after all programming operations. The operation of the Read instruction is independent of both the EWEN and EWDS instructions and can be executed at any time.75193F–SEEPR–1/08AT93C46D3.Timing DiagramsFigure 3-1.Synchronous Data TimingNote: 1.This is the minimum SK period.Figure 3-2.READ TimingTable 3-1.Organization Key for Timing DiagramsI/O AT93C46D (1K)x 8x 16A N A 6A 5D ND 7D1585193F–SEEPR–1/08AT93C46DFigure 3-3.EWEN TimingFigure 3-4.Figure 3-5.WRITE Timing95193F–SEEPR–1/08AT93C46DFigure 3-6.WRAL Timing (1)Note:1.Valid only at V CC = 4.5V to 5.5V .Figure 3-7.ERASE Timing105193F–SEEPR–1/08AT93C46DFigure 3-8.(1)Note:1.Valid only at V CC = 4.5V to 5.5V .115193F–SEEPR–1/08AT93C46DNotes:1.“-B” denotes bulk2.“-T” denotes tape and reel.
