Pixel Clock Input for HD Only (74.25 MHz), PS Only (27 MHz), SD Only (27 MHz).
Pixel Clock Input. Requires a 27 MHz reference clock for progressive scan mode or a 74.25 MHz
(74.1758 MHz) reference clock in HDTV mode. This clock is only used in dual modes.
Compensation Pin for DACs. Connect 0.1

CVBS/Green/Y/Y Analog Output.
Chroma/Blue/U/Pb Analog Output.
Luma/Red/V/Pr Analog Output.
In SD Only Mode: CVBS/Green/Y Analog Output; in HD Only Mode and Simultaneous HD/SD
Mode: Y/Green [HD] Analog Output.
In SD Only Mode: Luma/Blue/U Analog Output; in HD Only Mode and Simultaneous HD/SD
Mode: Pr/Red Analog Output.
In SD Only Mode: Chroma/Red/V Analog Output; in HD Only Mode and Simultaneous HD/SD
Mode: Pb/Blue [HD] Analog Output.
Video Horizontal Sync Control Signal for HD in Simultaneous SD/HD Mode and HD Only Mode.
Video Vertical Sync Control Signal for HD in Simultaneous SD/HD Mode and HD Only Mode.
Video Blanking Control Signal for HD in Simultaneous SD/HD Mode and HD Only Mode.
Video Blanking Control Signal for SD Only.
Video Horizontal Sync Control Signal for SD Only.
Video Vertical Sync Control Signal for SD Only.
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.
Progressive Scan/HDTV Input Port 4:4:4 Input Mode. This port is used for the Cb[Blue/U] data.
The LSB is set up on Pin C0.
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.
This input resets the on-chip timing generator and sets the ADV7312 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 Interface Clock Input.
I
2
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 ADV7312 to interface over the I
