V
A A
.
DAC A
O
CVBS/ GREEN/ Y SD analog output.
DAC B
O
Luma/ BLUE/ U SD analog output.
DAC C

and HD only mode.
P_VSYNC
I
Video Vertical Sync Control Signal for HD sync in simultaneous SD/HD mode and
HD only mode.
S_BLANK
I/O
Video Blanking Control Signal for SD.
S_HSYNC
I/O
Video Horizontal Control Signal for SD. Option to o/p SD HSYNC or HD HSYNC
in SD Slave Mode 0 and/or any HD mode.
S_VSYNC
I / O
Video Vertical Control Signal for SD. Option to o/p SD VSYNC or SD
HSYNC in SD Slave Mode 0 and/or any HD mode.
C 7 - 0
I
8-Bit Progressive scan/ HDTV input port for CrCb color data in 4:2:2 input
mode. In 4:4:4 input mode this input port is used for the Cb [Blue/U] data.
The LSB is set up on pin C0. In default mode the input on this port is
output on DAC E.
Y 7 - 0
I
8-Bit Progressive scan/ HDTV input port for Y data. The LSB is set up
on pin Y0. In default mode the input on this port is output on DAC D.
S 7 - S 0
I
8-Bit Standard Definition input port. Or Progressive Scan/ HDTV input port
for Cr [Red/V] color data in 4:4:4 input mode. The LSB is set up on pin
S 0 .
In default mode the input on this port is output on DAC F.
RESET
I
This input resets the on-chip timing generator and sets the ADV7302A/03A
into Default Register setting. Reset is an active low signal.
