PIN FUNCTION DESCRIPTIONS
Input/Output
Digital Ground
Analog Ground
Pixel Clock Input. Requires a 27MHz reference clock for Progressive Scan
Mode or a 74.25MHz (74.1758MHz) reference clock in HDTV mode. This
clock input pin is only used in simultaneous SD and HD mode.
Pixel Clock Input for HD only or SD only modes.
Compensation Pin for DACs. Connect 0.1 µF Capacitor from COMP pin to
V
.
AA
CVBS/ GREEN/ Y SD analog output.
Luma/ BLUE/ U SD analog output.
Chroma/ RED/ V SD analog output.
in SD only mode: CVBS/GREEN/ Y analog output
in HD only mode and simultaneous HD/SD : Y/ GREEN (HD) analog output.
in SD only mode: Luma/BLUE/ U analog output
in HD only mode and simultaneous HD/SD : Pr/ RED (HD) analog output.
in SD only mode: Chroma/RED/ V analog output
in HD only mode and simultaneous HD/SD : Pb/ BLUE (HD) analog output.
Video Blanking Control Signal for HD sync in simultaneous SD/HD mode and HD
HD only mode.
Video Horizontal Sync Control Signal for HD sync in simultaneous SD/HD mode
and HD only mode.
Video Vertical Sync Control Signal for HD sync in simultaneous SD/HD mode and
HD only mode.
Video Blanking Control Signal for SD.
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.
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.
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.
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.
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.
This input resets the on-chip timing generator and sets the ADV7302A/03A
into Default Register setting. Reset is an active low signal.
