Pin Configuration Table 9. Pin Function Descriptions Pin No. Mnemonic Input/ Output Description 1, 11, 20, 28, 30 VAA P Power Supply (3 V to 5 V). 2 to 9, 12 to 14, 38 to 42 P15 to P0 I 8-Bit 4:2:2 Multiplexed YCrCb Pixel Port (P7 to P0) or 16-Bit YCrCb Pixel Port (P15 to P0). P0 represents the LSB. 10, 19, 21, 29, 43 GND G Ground Pin. 15 HSYNC I/O HSYNC (Mode 1 and Mode 2) Control Signal. This pin may be configured to output (master mode) or accept (slave mode) sync signals. 16 FIELD/VSYNC I/O Dual Function FIELD (Mode 1) and VSYNC (Mode 2) Control Signal. This pin may be configured to output (master mode) or accept (slave mode) these control signals. 17 BLANK I/O Video Blanking Control Signal. The pixel inputs are ignored when this is Logic Level 0. This signal is optional. 18 ALSB I TTL Address Input. This signal sets up the LSB of the MPU address. 22 RESET I The input resets the on-chip timing generator and sets the ADV7170/ADV7171 into default mode. This is NTSC operation, Timing Slave Mode 0, 8-bit operation, 2 × composite and S-Video out, and DAC B powered on and DAC D powered off. 23 SCLOCK I MPU Port Serial Interface Clock Input. 24 SDATA I/O MPU Port Serial Data Input/Output. 25 COMP O Compensation Pin. Connect a 0.1 μF capacitor from COMP to VAA. For optimum dynamic performance in low power mode, the value of the COMP capacitor can be lowered to as low as 2.2 nF. 26 DAC C O RED/S-Video C/V Analog Output. 27 DAC D O GREEN/S-Video Y/Y Analog Output. 31 DAC B O BLUE/Composite/U Analog Output. 32 DAC A O PAL/NTSC Composite Video Output. Full-scale output is 180 IRE (1286 mV) for NTSC and 1300 mV for PAL. 33 VREF I/O Voltage Reference Input for DACs or Voltage Reference Output (1.235 V). 34 RSET I A 150 Ω resistor connected from this pin to GND is used to control full-scale amplitudes of the video signals. |
