PIN FUNCTION DESCRIPTIONS
Function
Digital Power Supply
10-Bit Progressive Scan/HDTV Input Port for Y Data. Input for G data when
RGB data is input.
Digital Ground

In 4:2:2 mode this input port is not used. Input port for R data when RGB
data is input.
Analog Power Supply
Pixel Clock Input. Requires a 27 MHz reference clock for standard operation in
Progressive Scan Mode or a 74.25 MHz (74.1758 MHz) reference clock in
HDTV mode.

A 2470 Ω resistor for input ranges 64–940 and 64–960 (output standards EIA-
770.1–EIA-770.3) must be connected from this pin to ground and is used to
control the amplitudes of the DAC outputs. For input ranges 0–1023 (output
standards RS-170, RS-343A) the R
Optional External Voltage Reference Input for DACs or Voltage Reference Out-
put (1.235 V)
This input resets the on-chip timing generator and sets the ADV7195 into Default
Register setting. Reset is an active low signal.
