Input/Output Description
I
This input resets the on-chip timing generator and sets the ADV7324 to its 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 ADV7324 to interface over the I
2
C port.
Digital Input/Output Ground.
