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.
