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. For 8-bit data input, LSB is set up on Y2.
The LSB is set up on pin C0. For 8-bit data input, LSB is set up on C2.
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 ADV7310/ADV7311 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.
