Description
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 Ω resistor must be connected from this pin to AGND and is used to control the
amplitudes of the DAC outputs.
