DESCRIPTION
Input return bias voltage.
This pin must be decoupled to AGND via a capacitor.
Selectable analogue output voltage for RLC or single-ended bias reference.
This pin would typically be decoupled to AGND via a capacitor.
VRLC can be externally driven if programmed Hi-Z.
Analogue ground (0V).
Blue channel input video.
Analogue ground (0V).
Green channel input video.
Analogue ground (0V).
Red channel input video.
Analogue ground (0V).
Digital supply (5V) for logic and clock generator. This must be operated at the same
potential as AVDD.
Output Hi-Z control, all digital outputs disabled when OEB = 1.
Serial interface: enable pulse, active high
Latched on NRESET rising edge: if Low then device control is via serial interface,
if high then device control is via parallel interface.
Serial interface: serial input data signal

Master clock. This clock is applied at N times the input pixel rate (N = 2, 3, 6, 8 or
any multiple of 2 thereafter depending on input sample mode).
Digital ground (0V).
