２ ＨＤＢ３的编解码及实现原理ＨＤＢ３码（三阶高密度双极性码）是基带电信设备之间进行基带传输的主要码型之一。

它的主要特点是易于提取时钟、不受直流特性影响、具有自检能力、连令串小于３个等。

Ｅ１信号是我国和欧洲国家电信传输网一次群使用的传输系统。

Ｅ１信号由３２个６４ｋｂｐｓ的ＰＣＭ话路经过时分复用形成。

ＣＣＩＴＴ建议Ｇ．７０３标准详细规定了ＨＤＢ３码用于Ｅ１信号的标准。

用ＸＣ９５７２实现Ｅ１信号的ＨＤＢ３编解码电路比较简单，而且无需可调整外围电路。

本设计使用了ＰＣ４４封装形式的ＸＣ９５７２可编程逻辑器件共有３０个可编程ＩＯ引脚、６个电源引脚和４个ＪＴＡＧ引脚。

整个设计使用了ＸＣ９５７２器件８０％的容量。

图２所示是其实现电路图。

ＨＤＢ３码是ＡＭＩ（ＡｌｔｅｒｎａｔｅＭａｒｋＩｎｖｅｒｓｉｏｎ）码的改进型。

ＡＭＩ码是用交替极性的脉冲表示码元“１”，用无脉冲表示码元“０”。

为了防止电路长时间出现无脉冲状态，ＨＤＢ３码的编码规则是：当没有４个或４个连续的“０”码时，就按ＡＭＩ码规则编码；当出现４个或４个连续的“０”码时，每４个连续“０”的第一个“０”的变化应视它前面相邻的“１”的情况而定，如果它的前一个“１”的极性与前一个破坏点的极性相反而本身就是破坏点，则４个连续的“０”的第一个仍保持“０”；如果它的前一个“１”的极性与前一个破坏点的极性相同而本身就是破坏点，则第一个“０”改为“１”。

Each channel can be configured to function either in on/off mode or in constant current mode by setting the appropriate MODE bit in SPI message #7.1.3.1On / Off Mode OperationFor On/Off operation, the POSx and NEGx pins must be connected to the circuit in either of the configurations shown in Figure1. If the sense resistor is included, the load current can be monitored by the microcontroller via a SPI command. The open load in on state fault detection feature is disabled in on/off mode.Note:An external flyback clamp is required in this configuration otherwise the IC may be damaged.1.3.2Constant Current Mode OperationDuring constant current operation, the POSx and NEGx pins must be connected to the circuit in the configuration shown in Figure 2.Note:An external recirculation diode is required in this configuration otherwise the IC may be damaged.The constant current control circuit can operate in two modes; steady state mode and transient mode.Steady-State ModeDuring steady-state operation, the PWM control signal driven at the OUTx pin is controlled by the control loop shown in Figure 3. The PWM Frequency is programmed via the SPI message # 1. In this message the main period divider, N, can be set to any value between 79 and 214 -1. The equation for calculating the PWM frequency is:NF F CLK PWM *32=The 11 bit Current Set Point is programmed via the SPI message #3. The equation for calculating the current setpoint is:The Proportional coefficient (KP) and the Integral coefficient (KI) of the control loop are programmed in SPImessage #5. The KP and KI values should be set to values that result in the desired transient response of the control loop. The duty cycle of the OUTx pin can be calculated from the difference equations:where error is the difference between the commanded average current and measured average current in units of Amps.where k indicates the integral number of PWM periods that have elapsed since current regulation was initiated.Auto ZeroWhen a channel is configured for constant current operation and the current set point is 000h for 256 consecutive PWM periods, an autozero sequence is initiated. The autozero sequence will measure the offset of the current SENSE setpoint R (11bit)t setpoin mA Current 3202][11∗=()()())1(1*28.1)()(1*28.1−+−∗∗=+−∗∗=k INT k error NRsenseKI k INT k INT k error N RsenseKP k DutyCyclemeasurement amplifiers. If the autozero function is enabled in SPI message #7, then the measured offset will be subtracted from the A/D converter output as shown in Figure3 when the current set point is greater than 0.DitherA triangular dither waveform can be superimposed on the current set point by setting the Dither Enable bit in SPI message #3. The amplitude and frequency of the dither waveform are programmed for each channel via SPI messages #3 and #4. See the SPI message section for details.The first programmed value is the step size of the dither waveform which is the number of bits added or subtracted from the setpoint per PWM period. One LSb of the dither step size is 1/16 the magnitude of the nominal setpoint current value. The second programmed value is the number of steps in one quarter of the dither waveform. When dither is enabled, a new average current set point will not be activated until the current dither cycle has completed. The dither cycle is completed on the positive zero crossing of the dither waveform. A new dither amplitude setting, a new dither frequency setting, or a dither disable command will also not be activated until the current dither cycle has completed see Figure4.Note: the actual dither waveform is attenuated and phase shifted according to the frequency response of the control loop.If a channel enters transient mode operation while the dither waveform is active, the dither wave-form will pause until transient mode is exited.Transient ModeWhen a large change in the current set point occurs, the device can be programmed to enter transient mode of operation. The setpoint change threshold required to initiate transient mode can be programmed in SPI message#6. The purpose of this mode of operation is to reduce the transition time of the load current after a large change in setpoint. In this mode of operation the OUTx pin signal is controlled by the state machine shown in Figure5. The control method in this mode is similar to hysteretic control, the OUTx signal transitions high or low based on the immediate value of the measured output current. The PWM frequency is not fixed in this mode of operation. The device will automatically switch from transient mode of operation to steady state operation at the start of the first PWM period after the new set point has been reached.A typical current waveform during transient mode operation is shown in Figure6. Starting from a set point I, the new set point II is accepted a short time after the rising edge on CS_B. The OUTx pin remains high until the measured load current has reached the new set point. The OUTx pin is then toggled on and off to maintain the load current near the new set point until the next PWM period begins. The device will then switch back to steady state control and the OUTx pin will be controlled by the control loop shown in Figure3.During the transition from transient mode operation to steady state operation, the integrator is pre-loaded with a SPI programmable value. This value should be chosen to give an initial PWM duty cycle approximately equal to the duty cycle required to regulate the load current at the new set point.Block Diagram 2Block DiagramPin Configuration3Pin Configuration3.1Pin Assignment3.2Pin Definitions and FunctionsPin Symbol I/O Analog /DigitalFunction 1OUT3O A Gate driver output for channel #3.

If not otherwise specified, typical characteristics apply at T A = 25 o C and the given supply voltage.5.1Supply and ReferenceThe device includes a power-on reset circuit. This feature will disable the channels and reset the internal registers to their default values when the voltage on V5A and/or V5D are below their respective reset thresholds.The V5D pin and GND_D pin are the supply and ground pins for the digital circuit blocks and the OUTx pin driver circuits. The current through these pins contain high frequency components. Decoupling with ceramic capacitors and careful PCB layout are required to obtain good EMC performance.The V5A pin and GND_A pin are the supply and ground pins for the analog circuit blocks.The V_SIGNAL pin supplies the SPI output pin (SO) and is the source voltage for the pull up currents on the CS_B and RESET_B pins. V_SIGNAL should be connected to the I/O supply of the microcontroller (3.3V or 5.0V). The BAT pin is an input pin used to detect over voltage faults. This pin is not a power supply input. A series resistor should be connected between this pin and the solenoid supply voltage for transient protection.Electrical Characteristics:V5D=4.75V to 5.25V, Vbat=5.5V to 42V, T j = -40 °C to +150 °C, all voltages with respect to ground, positive current flowing into pin (unless otherwise specified)Pos.Parameter Symbol Limit Values Unit ConditionsMin.Typ.Max.5.1.1Undervoltage reset (internallytriggered)VV5A3.5–4.5V Internal resetoccurs if V5A isunder theundervoltage limit5.1.2Undervoltage reset (internallytriggered)VV5D1.0– 4.5V Internal resetoccurs if V5D isunder theundervoltage limit5.1.3V5D supply current I V5D––3050mAmAfCLK=20MHzfCLK=40MHz5.1.4V5A supply current I V5A––25mA5.1.5V_SIGNAL supply current I V_SIGNAL–– 1.0mA SO pin in hi-Z state,digital inputs indefault state5.1.6VBAT current I VBAT––150505µAµAµAfull operating rangeV5A=5V, BAT=14V1)V5A=0V, BAT=14V1)1)Not subject to production test, specified by design.Functional Description and Electrical Characteristics5.2Input / OutputAll digital inputs are compatible with 3.3 V and 5 V I/O logic levels. The supply voltage for the SPI output SO is the V_SIGNAL pin. All digital inputs are pulled to a known state by a weak internal current source or current sink when not connected. However, unused digital input pins should be connected to ground or to V_SIGNAL (according to the desired functionality) by an external connection or resistor. All input pin weak internal current sources are supplied by the V_SIGNAL pin.The RESET_B pin is an active low input pin. When this pin is low, all channels are off, and all internal registers are reset to their default states. The device must be held in reset by an external source until all the power supplies have stabilized. The IC contains an internal power on and undervoltage reset which becomes active when V5D or V5A fall below the undervoltage reset threshold (VUVA, VUVD).The ENABLE pin is an active high input pin which must be held high for normal operation of the device. When this pin is held low all channels are either turned off or will remain in the last state, depending on how the enable behavior of the channel is programmed via SPI. The default condition is that all channels are turned off when the ENABLE pin is low.The CLK pin is the main clock input for the device. The input thresholds are compatible with 3.3 V and 5.0 V logic levels. No synchronization is required between the clock signal connected to the CLK pin and the SPI clock signal (SCK). All frequencies of operation (PWM signals, A/D sampling, diagnostics, etc.) are based on this clock input.Also, this clock is required in order for the device to accept and respond to SPI messages.The PHASE_SYNC pin is an input pin that can be used by the microcontroller to synchronize the PWM control signals of multiple channels. The desired phase delay between the rising edge of the signal applied to the PHASE_SYNC pin and the rising edge of the PWM signal of each channel can be programmed independently via SPI message #2. The equation for calculating the offset is:Each time the phase sequence occurs, the IC will latch a bit which is reported via the response to SPI message #11. (See SPI interface section for bit/message location.) This latch is cleared when the message is read.Note:The PWM periods are restarted when a rising edge is detected on the PHASE_SYNC pin. A periodic pulsetrain on this pin will disturb the current regulation.PWMoffset F OffsetPhaseSynch T *32=Functional Description and Electrical CharacteristicsThe TEST pin is an input pin that is used during IC level test. This pin should be connected directly to ground for normal device operation.The FAULT pin is an open drain output pin. This pin will be pulled low by the device when an unmasked fault has been detected. The fault masks are programmed via SPI message #7.Electrical Characteristics:V5D =4.75V to 5.25V, Vbat =5.5V to 42V, T j = -40 °C to +150 °C, all voltages with respect to ground, positive current flowing into pin (unless otherwise specified)5.3DiagnosticsThe TLE7242 2G includes both on-state and off-state diagnostics. On-state diagnostics are active when the OUTx pin is driven high and off-state diagnostics are active when the OUTx pin is driven low. A detected fault can be used to activate the open drain FAULT pin on the IC.

not need to be reset e the voltage applied to the clutch for resetting with the H2C-R.Do not allow power to be continuously applied to the motor and clutch for extended periods of time.OthersDo not turn the operation time setting knob beyond the range of the scale.To achieve higher accuracy in setting,measure the operation time while turning the operation time setting knob.The deviation and setting error for the operation time shows the per-cent of FS.The absolute value of the deviation and setting error will not change even if the set time is changed.The time specifications should therefore be selected to use the operation time as close to FS as possible.At high temperatures,the operation voltage will be 90%or less if voltage is applied continuously after timeout.Be sure to keep the voltage within the allowable voltage fluctuation range.ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.To convert millimeters into inches,multiply by 0.03937.To convert grams into ounces,multiply by

All Rights Reserved.DESCRIPTIONThe WT272C/WT274C is a dual/quad low power CMOS operational amplifiers IC. It provides high performance operation at low supply voltages. The basic amplifier can operate at supply voltage as low as 1.2V with very low power consumption and makes it perfect for battery-powered application. The input common-mode voltage extends to the negative rail. The output swings to both rails with light load. The input bias current is inherently low and the input impedance is extremely high. The devices are ideal upgrades for industrial standards OP amp.FEATURES• Low Power Replacement for Standard OP Amps• Wide supply operating range (1.2V to 7V)• Input common-mode voltage range includes negative rail• Output swing to rail• Low input bias current (typical 1pA)• High input impedance• Single supply operation• Internal compensated• Output short circuit protectionAPPLICATIONS ORDERING INFORMATION•Portable Instruments Part Number Package Part Number Package •Battery-Powered Systems WT272C-N0808 pin PDIP WT274C-N14014 pin PDIP •Transducer Interfacing WT272C-S0808 pin SO WT274C-S14014 pin SO •Active FilterABSOLUTE MAXIMUM RATINGSParameter Min.Max.UnitsDC supply voltage (V+− V−)08.5VInput and output voltage V− - 0.3V++ 0.3V Storage temperature-65150O C Ambient temperature with power applied-20100O C Duration of output short circuit Unlimited*Note: Stresses above those listed may cause permanent damage to the devices RECOMMENDED OPERATING CONDITIONSymbol Parameter Condition Min.Typ.Max.Units V SUPPLY Supply Voltage 1.27V I SOURCE Output Source Current5mA I SINK Output Sink Current9µA Ta Ambient Temperature085O C ELECTRICAL CHARACTERISTICS(V+ = 5V, V−= 0V, Ta = +25 O C unless otherwise specified)Symbol Parameter Condition Min.Typ.Max.Units V OS Input Offset Voltage25mV êV OS/êT Average TemperatureCoefficient of Input OffsetVoltage0.7µV/O CI OS Input Offset Current1pA I BIAS Input Bias Current Ta=25 O C1pA V ICOM Input Common Mode Voltage0V+ -1.3VVin =10mVR L=1MΩ connected to V−4.9 4.99VVin =10mVR L=100KΩ connected to V−4.95VVin =10mVR L=10KΩ connected to V−4.75VVin = -10mVR L=1MΩ, connected to V+0.50.7VV OUT Output Voltage SwingVin = -10mVR L=100KΩ connected to V+0.65VA VOL Large Signal Voltage Gain V O= 1V to 4V, Vi=1.4VR L=1MΩ20100V/mV GBW Unit Gain Bandwidth R L=1MΩ, C L=50pF0.1MHz CMRR Common Mode Rejection Ratio V O= 1V, Vi=0 to 3.5V6080dB PSRR Power Supply Rejection Ratio V O= 1V6090dB SR Slew Rate A VOL=1, C L=100pFV IN=5V P-P0.03V/µsI SUPPLY Supply Current (per amplifier)59µA ϕm Phase Margin at Unit Gain R L=1MΩ, C L=50pF55Degree e n Input Equivalent Noise Voltage f=1KHz, Rs=100Ω50nV/√Hz V O1/V O2Channel Separation A VOL=100120dBTYPICAL APPLICATION CIRCUIT Voltage Follower。

®EL7242, EL7252Dual Input, High Speed, Dual Channel Power MOSFET DriverThe EL7242/EL7252 dual input, 2-channel drivers achieve the same excellent switching performance of the EL7212 family while providing added flexibility. The 2-input logic and configuration is applicable to numerous power MOSFET drive circuits. As with other Elantec drivers, theEL7242/EL7252 are excellent for driving large capacitive loads with minimal delay and switching times. “Shoot-thru” protection and latching circuits can be implemented by simply “cross-coupling” the 2-channels.Features•Logic AND/NAND input •3V and 5V Input compatible •Clocking speeds up to 10MHz •20ns Switching/delay time •2A Peak drive •Isolated drains •Low output impedance •Low quiescent current•Wide operating voltage — 4.5V16V •Pb-Free available (RoHS compliant)Applications•Short circuit protected switching •Under-voltage shut-down circuits •Switch-mode power supplies •Motor controls•Power MOSFET switching •Switching capacitive loads •Shoot-thru protection •Latching driversPinoutsOrdering InformationPART NUMBER PACKAGE TAPE &REELPKG.
