The AWT6332 uses ANADIGICS’ exclusive InGaP-Plus™ technology, which combines HBT and pHEMT devices on the same die, to enable state-of-the-art reliability, temperature stability, and ruggedness.The AWT6332 has a unique architecture with two RF inputs. One input drives the power amplifier while the other input drives an RF switch that bypasses the power amplifier, going directly to the RF output. The mode control logic selects the PA or the RF switch. InFigure 1: Block DiagramRF switch mode, current consumption is less than 10 A, reducing the average current consumption 70% more than a HELP2™ PA over the CDG profile. Its integrated voltage regulator eliminates the need for external components further reducing size and BOM cost.

PWM Counter and Output TimingFunctional DescriptionFigure 4. Functional DiagramShift RegisterThe A6281 has a 32-bit shift register that loads data through the SDI (serial data in) pin. The shift register operates by a first-in first-out (FIFO) method. The most significant bit (MSB, bit 31) is the first bit shifted in and the least significant bit (LSB, bit 0) is shifted in last. The serial data is clocked by a rising edge of the CI (clock in) pin. The SDO (serial data out) pin is updated to the state of bit 31 on the falling edge of the CI pin. This will prevent any race conditions and erroneous data that might occur while propagating information through multiple A6281s that are daisy chained together. The contents of the shift register will continue to propagate on every rising edge of the CI pin. The information in the shift register is latched on a low-to-high transition of the LI (Latch In) pin. The LI pin must be brought low before the rising edge of the next clock pulse, to avoid latching erroneous data. The latched data remains latched on a rising signal on the OEI (output enable in) pin.Output BuffersThe A6281 is designed to allow daisy chaining many A6281s together. It can pass the clock, data, latch, and output enable signals from one A6821 to the next without any loss of data due to duty cycle skewing or signal degradation.The A6821 is equipped with output buffers that allow the data signals to travel over long distances through strings of A6281s without the need for extra driving hardware. The A6281 drivesthese signals to TTL levels. Each of the A6281 inputs has a cor-responding buffered output:• CI (clock in) pin to CO (clock out) pin • LI (latch in) pin to LO (latch out) pin• OEI (output enable in) pin to OEO (output enable out) pin • SDI (serial data in) pin to SDO (serial data out) pinThe CO (clock out) pin is driven by an internal one-shot circuit. When the CI pin detects an edge rising through the input thresh-old, the one-shot circuitry drives the CO pin high for 100 ns. The CI pin input threshold has hysteresis to prevent false triggering of the CO signal. The implementation of the one-shot solution allows many A6281s to be daisy chained together with a consis-tent clock signal throughout the entire chain without degradation or loss of synchronicity to the data line. PWM Brightness ControlThe A6281 controls the intensity of each LED by pulse width modulating the current of each output. The A6281 has three10-bit brightness registers, one for each output. These brightness registers set the PWM count value at which the outputs switch off during each PWM cycle. Each 10-bit brightness register gives 1023 levels of light intensity. The duty cycle, DC, can be deter-mined by the following equation:DC = [(PWM n + 1) / 1024] ×100 (%) ,where PWM n is the PWM value greater than zero that is stored in the brightness register.RThe relationship of the PWM n value to the output duty cycle is given in the following table:PWM n Duty Cycle00/1024 (0 %)12/102423/1024. . .. . .10231024/1024 (100 %)When the brightness register is set to zero, the outputs remain off for the duration of the PWM cycle for a 0% DC. When a bright-ness register is set to 1023, the LED for that output remains on (100% DC) when OEI is active and begins the PWM cycle. The output remains on when the PWM counter rolls over and begins a new count.The PWM counter begins counting at zero and increments only when the OEI pin is held low. When the PWM counter reaches the count of 1024, the counter resets to zero and continues incrementing. The counter resets to zero on a rising edge of OEI, upon recovery from UVLO, or when powering up. Latching new data into the brightness registers will not reset the PWM counter.A free-running internal 800 kHz oscillator is the master clock for the PWM counter. A programmable clock divider frequency allows the PWM to be set at approximately at 200 kHz, 400 kHz, or 800 kHz, or the PWM can be set to count on the rising edge of the external CI signal. Bit assignments for the programmable clock divider are shown in the following table:BitsClock Mode7810400 kHz01External (count on rising edge of CI signal)11200 kHzThe total number of possible colors of an RGB pixel is over1 billion. Refer to figure 4 for the mapping of shift register bits to latches.Output Current SelectionThe overall maximum current is set by the external resistor,R EXT, connected between the REXT and LGND pins. After being set, the maximum current remains constant regardless of the LED voltage variation, supply voltage variation, temperature, or other circuit parameters. The maximum output current can be calculated using the following equation:I OUT(max)= 753.12 / R EXT.The relationship of the value selected for R EXT and I OUT is shown in figure 6.Internal Linear RegulatorThe A6281 has a built-in linear regulator. The regulator operates from a supply voltage of 5.5 to 17 V. It allows the VIN pin of the A6281 to connect to the same supply as the LEDs. This simpli-fies board design by eliminating the need for a chip supply bus and external voltage regulators. For 5 V supplies, connect VIN to VREG externally. Note: When using 5 V supplies, ensure that VIN does not exceed the absolute maximum rating of the VREG pin (6 V).The V REG pin is used by the internal linear regulator to connect to a bypass capacitor. This pin is for internal use only and is notBits 0123456789101112131415161718192021222324252627282930a31 PWM Counter 0PWM Counter 1PWM Counter 2Address “0”X bDot Correction Register 0ClockModeXDot CorrectionRegister 1X X XDot CorrectionRegister 2X ATB c ATB c Address “1”Xa Selects which word is written to: Dot Correction/Clock Mode selection or PWM counter.b X indicates “Don’t Care.”c Allegro Test Bit (ATB).

Output Current versus External Resistor, R EXTintended as an external power source. There should be a 1.0 μF, 10 V ceramic capacitor connected between the V REG pin and LGND. The capacitor should be located as close to the V REG pin as possible.Dot Correction ControlThe A6281 can further control the maximum output current for each output by setting the three 7-bit dot correction registers with scale data that ranges from 36.5% to 100% of the overall maximum output current that is set by the REXT resistor. This feature is useful because not every type of LED (red, green, or blue, for example) has the same level of brightness for a given current, and the brightness could be different even from LED to LED of the same type. By scaling the output currents so that all the LEDs have matched intensities, the application will have full color depth when using the PWM counters. The dot correction current can be calculated by the following equation:I OUT n = I OUT n(max) × (Scale n / 2 + 36.5) / 100Where Scale n is in the range 0 to 127, as shown in the following table:Scale I OUT/I OUT(max)(%)036.5137.0237.5. . .. . .127100Refer to figure 5 for the bit configurations for the scalar registers.The dot correction data in the shift register is latched on a rising edge of the LI pin. The dot correction data remains latched on a rising OEI signal. The default output current when the A6281 is powered-up or recovers from a UVLO is 36.5% of the current set by the R EXT resistor.Package Power DissipationThe maximum allowable package power dissipation is deter-mined as:P D(max) = (150 – T A) / RθJA .The actual package power dissipation is:P D(act) = DC0 × V DS0 × I OUT0+ DC1 × V DS1 × I OUT1+ DC2 × V DS2 × I OUT2 + V IN × I IN , where DC i is the PWM duty cycle for channel i, and I OUTi is the output current for channel i, determined by the dot correction current for that channel and REXT.When calculating power dissipation, the total number of avail-able device outputs is usually used for the worst-case situation (3 LEDs at 100% duty cycle).Thermal Shutdown (TSD)When the junction temperature of the A6281 reaches the thermal shutdown temperature threshold, T JTSD (165°C typical), the outputs will shut off until the junction temperature cools down below the recovery threshold, T JTSD –∆T J ( 15°C typical). The shift register and output latches will remain active during the TSD event. Therefore there is no need to reload the data into the output latches.Undervoltage LockoutThe A6281 includes an internal undervoltage lockout (UVLO) circuit that disables the driver outputs in the event of the logic supply voltage dropping below a minimum acceptable level. This prevents the display of erroneous information, a necessary function for some critical applications. The shift register will not shift any data in a UVLO condition. Upon recovery of the logic supply voltage and on power up, the internal shift register and all latches will be set to zero.Ballast ResistorsThe voltage on the outputs should be kept in the range 1 to 3 V. If the voltage goes below 1V, the current will begin to rolloff as the driver runs out of headroom. At V OUT above 3 V, the power dissipation may become a problem, as each output contributesV OUT × I LED of power loss in the output sink driver. Typically the power supply nominal voltage is chosen to keep the output volt-age in this range. Alternatively, series resistors can be added to dissipate the extra power and keep the output voltage within the recommended range.Application InformationTiming ConsiderationsA6281s can be used in large numbers to drive many LEDs with the control signals connected serially together using short cables between each pixel (see figure 8). Because the clock negative edge drives the data to the SDO pin, and the CO pin is driven by a 100 ns one-shot function, the clock and data signals remain synchronized with each other from the first pixel in the chain to the last.After all of the data is written to each A6281 in the chain, the data is latched into each A6281 via a low-to-high transition on the LI pin. The LO pin of pixel #1 drives the LI pin of pixel #2, and so on down the chain. These signals are buffered and are driven asynchronously relative to the CI and SDI pins. Therefore the mismatch in delays between CO and LO must be taken into consideration.Although the mismatches in delays are quite small, they must be considered when creating the timing pattern for driving the chain. The key parameter is the setup time from the last CI clock rising edge to the rising edge of LI.The minimum A6281 setup time from CI to LI is 20 ns. There may be a 5 ns per pixel mismatch in the propagation delays of the CI and LI signals (the delay from CI to CO compared to the delay from LI to LO). As a rule of thumb, use a setup time, t su , at the first A6281 in the chain as calculated below:t su = 20 ns + n × 5 ns ,where n is the number of pixels in the chain.This will ensure that the setup time at the last pixel in the chain is at least 20 ns.Figure 7. Signal Delay Mismatch Timing Diagram. t su is the setup time for signals (CI to LI) applied to the first pixel in the chain. Note the difference in delay for CI(1) to CI(n ) compared to the delay for LI(1) to LI(n ). This must be compensated by increasing t su .CO(1)=CI(2)CI(1)CO(2)=CI(3)CO(n -1)=CI(n )LI (1)LO(1)=LI (2)LO(2)=LI (3)LO(n -1)=LI (n ))Applications Drawings8.5 VFigure 9.
