Ground Pin.
HSYNC
(Modes 1 and 2) Control Signal. T his 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. T his
pin may be configured to output (Master Mode) or accept (Slave Mode)
these control signals.
Video Blanking Control Signal. T he pixel inputs are ignored when this is
logic level “0.” T his signal is optional.
T T L Address Input. T his signal sets up the LSB of the MPU address.
T he input resets the on chip timing generator and sets the ADV7175A/
ADV7176A into default mode. T his is NT SC operation, T iming Slave Mode

composite and S-Video out and all DACs powered on.
MPU Port Serial Interface Clock Input.
MPU Port Serial Data Input/Output.
Compensation Pin. Connect a 0.1
μ
F capacitor from COMP to V
AA
. For
Optimum Dynamic Performance in L ow 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/NT SC Composite Video Output. Full-Scale Output is 180IRE (1286
mV) for NT SC and 1300 mV for PAL.
Voltage Reference Input for DACs or Voltage Reference Output (1.235 V).
A 150
resistor connected from this pin to GND is used to control full-scale
amplitudes of the video signals.
T his pin can be configured as an input by setting MR22 and MR21 of Mode
Register 2. It can be configured as a subcarrier reset pin, in which case a high
to low transition on this pin will reset the subcarrier to Field 0. Alternatively
it may be configured as a Real T ime Control (RT C) input.
T eletext Data Request Signal/Defaults to GND when T eletext not selected
(enables backward compatibility to ADV7175/ADV7176).
T eletext Data/Defaults to V
AA
when T eletext not selected (enables backward
compatibility to ADV7175/ADV7176).
8-Bit 4:2:2 Multiplexed YCrCb Pixel Port (P7–P0) or
16-Bit YCrCb Pixel Port (P0–P15). P0 represents the LSB.
T T L Clock Input. Requires a stable 27 MHz reference Clock for standard
operation. Alternatively, a 24.52 MHz (NT SC) or 29.5 MHz (PAL) can be
used for square pixel operation.
