.
CVBS/GREEN/Y Analog Output.
Chroma/BLUE/Pb Analog Output.
Luma/RED/Pr Analog Output.
Video Blanking Control Signal. For HD and PS, this input is active high. For SD
input, this input is active low.
Video Horizontal Sync Control Signal.
Video Vertical Sync Control Signal.
SD or Progressive Scan/HDTV Input Port for Y Data. Input port for interleaved
progressive scan data. The LSB is set up on Pin Y0.
8-Bit SD/Progressive Scan/HDTV Input Port. The LSB is set up on Pin C0.
This input resets the on-chip timing generator and sets the ADV7330 into the default
register setting. Reset is an active low signal.
A 3040
resistor must be connected from this pin to AGND and is used to control
the amplitudes of the DAC outputs.

C Port Serial Data Input/Output.
TTL Address Input. This signal sets up the LSB of the I
2
C address. When this pin is
tied low, the I
2
C filter is activated, which reduces noise on the I
2
C interface.
Power Supply for Digital Inputs and Outputs.
