Description
Power Supply (3 V to 5 V).
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.
Ground Pin.
HSYNC (Mode 1 and Mode 2) Control Signal. This pin may be configured to output (master
mode) or accept (slave mode) sync signals.
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.
Video Blanking Control Signal. The pixel inputs are ignored when this is Logic Level 0. This
signal is optional.
TTL Address Input. This signal sets up the LSB of the MPU address.
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.
MPU Port Serial Interface Clock Input.
MPU Port Serial Data Input/Output.
Compensation Pin. Connect a 0.1 μF capacitor from COMP to V
performance in low power mode, the value of the COMP capacitor can be lowered to as low
as 2.2 nF.
RED/S-Video C/V Analog Output.
GREEN/S-Video Y/Y Analog Output.
BLUE/Composite/U Analog Output.
PAL/NTSC Composite Video Output. Full-scale output is 180 IRE (1286 mV) for NTSC and
1300 mV for PAL.
Voltage Reference Input for DACs or Voltage Reference Output (1.235 V).
A 150 Ω resistor connected from this pin to GND is used to control full-scale amplitudes
of the video signals.
