P15-P0
I
8-Bit 4:2:2 Multiplexed YCrCb Pixel Port (P7–P0) or
16-Bit YCrCb Pixel Port (P15–P0). P0 represents the LSB.
T T L Clock Input. Requires a stable 27 MHz reference Clock for proper operation.
Alternatively a 24.52 MHz (NT SC) or 29.5 MHz (PAL) can be used for square pixel
operation.
HSYNC
(Modes 1 & 2) Control Signal. T his pin may be configured to output (Mas-
ter 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 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 con-
figured as a Real T ime Control (RT C) input.
Voltage Reference Input for DACs or Voltage Reference Output (1.2 V).
A 150
resistor connected from this pin to GND is used to control full-scale ampli-
tudes of the video signals.
Compensation Pin. Connect a 0.1
μ
F capacitor from COMP to V
AA
.
PAL/NT SC Composite Video Output. Full-Scale Output is 180IRE (1286 mV) for
NT SC and 1300 mV for PAL.
RED/S-VHS C/V Analog Output.
GREEN/S-VHS Y/Y Analog Output.
BLUE/Composite/U Analog Output.
MPU Port Serial Interface Clock Input.
MPU Port Serial Data Input/Output.
T T L Address Input. T his signal set up the LSB of the MPU address.
T he input resets the on chip timing generator and sets the ADV7175/ADV7176 into
default mode. T his is NT SC operation, T iming Slave Mode 0, 8-bit operation, 2
