6 / 18 page Data Sheet S12608EJ1V0DS00 4 µµµµ PD16780 4. PIN FUNCTIONS Pin Symbol Pin Name Description C1,C2,C3 Video signal input These pins are input video signals R,G, and B. S1-S300 Video signal input These pins are output video signals, which have been sampled and hold. C1: S3n-2 (n = 1, 2, ··········96/100) C2: S3n-1 C3: S3n STHR, STHL Cascade I/O These pins are inputs/outputs for the start pulse for sample and hold timing. High level of STHR/STHL is read at rising edge of CLK and start sampling video signal. STHR serves as the input pin and STHL serves as output pin for the right shift. For left shift, STHL serves as the input pins and STHR serves as the output pin. R,/L Shift direction switching input The shift directions of the shift registers are as follows. R,/L = H: STHR input, S1 → S300, STHL output. R,/L = L: STHL input, S300 → S1, STHR output. Osel Selection of Number of outputs switching input Selects number of outputs. Osel = L: 288 output mode Osel = H: 300 output mode Output pins S145 through S156 are invalid in 288 output mode. The signal which is with S157 to S168 (R,/L = H) or S133 to S144 (R,/L = L) is output identically. CLK Shift clock input The start pulse is read at rising edge of CLK. The sampling pulse SHPn is generated at rising edge of CLK. µ PD16780 corresponds only to LCD of Stripe array color filter and only simultaneous sampling. For details, refer to 6. TIMING CHART. CX Hold capacitance control input Two Sample & hold circuits are switched. CX = H S&H1: Sampling, S&H2: Output CX = L S&H1: Output, S&H2: Sampling TEST Test pin Fix this pin to the L level. VDD1 Logic power supply 3.3 V ± 0.3 V, or 5.0 V ± 0.5 V VDD2 Driver power supply 5.0 V ± 0.5 V VSS1 Logic ground Grounding VSS2 Driver ground Grounding VSS3 Sample & hold ground It is ground of Sample & hold capacitance. Supply this terminal with the stable GND. • |
