DESCRIPTION
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.
Video sample synchronisation pulse.
RLC (active high) selects reset level clamp on a pixel-by-pixel basis – tie high if
used on every pixel. ACYC autocycles between R, G, B inputs.
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).
Enables the serial interface when high.
Digital supply (5V/3.3V), all digital I/O pins.
Serial data input.
Serial clock.
Digital multiplexed output data bus.
ADC output data (d15:d0) is available in two multiplexed formats as shown, under
the control of register MUXOP [1:0]
See ‘Output Formats’ description in Device Description section for further details.
Alternatively, pin OP[7]/SDO may be used to output register read-back data when
OEB = 0 and SEN has been pulsed high. See Serial Interface description in Device
Description section for further details.
Analogue supply (5V). This must be operated at the same potential as DVDD1.
Analogue ground (0V).
Lower reference voltage.
This pin must be connected to AGND via a decoupling capacitor.
Upper reference voltage.
This pin must be connected to AGND via a decoupling capacitor.
Input return bias voltage.
This pin must be connected to AGND via a decoupling capacitor.
Selectable analogue output voltage for RLC or single-ended bias reference.
This pin would typically be connected to AGND via a decoupling capacitor.
VRLC can be externally driven if programmed Hi-Z.
Blue channel input video.
Green channel input video.
