DESCRIPTION
Analogue ground pin (0V)
Digital Core supply (3.3V)
Video sample synchronisation pulse.
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 I/O supply (2.5V-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 4-bit multiplexed format as shown below.
Alternatively, pin OP[3]/SDO may be used to output register read-back data when
address bit 4=1 and SEN has been pulsed high. See Serial Interface description in
Device Description section for further details.
Analogue supply (3.3V)
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.
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.
Video input pin.
