Input/Output Description
I
SD or Progressive Scan/HDTV Input Port for Cr[Red/V] Data in 4:4:4 Input Mode. LSB is set up
on Pin S0. For 8-bit data input, LSB is set up on S2.
This input resets the on-chip timing generator and sets the ADV7320/ADV7321 into 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.
Digital Power Supply.
Analog Power Supply.
Optional External Voltage Reference Input for DACs or Voltage Reference Output (1.235 V).
External Loop Filter for the Internal PLL.
Multifunctional Input. Real-time control (RTC) input, timing reset input, subcarrier reset input.
This input pin must be tied high (V
DD_IO
) for the ADV7320/ADV7321 to interface over the I
2
C port.
