Description
Red Channel input video
Green Channel input video
Blue Channel input video
Image compensation data read/write at twice ADC conversion rate
Master clock. This clock is applied at either six, four or two times the input
pixel rate depending on the operational mode. MCLK is divided internally to
define the ADC samples rate and to provide the clock source for digital logic.
Video sample synchronisation pulse. This signal is applied synchronously with
MLCK to specify the point in time that the input is sampled. The timing of
internal multiplexing between the R, G and B channels is derived from this
signal
Selects whether reset level clamp is applied on a pixel-by-pixel basis. If RLC
is required on each pixel then this pin can be tied high
Selectable analogue output voltage for RLC
ADC reference voltages. The ADC reference range is applied between
V
derive optimum reference voltages from an external 5V reference
Buffered mid-point of ADC reference string.
Tri-state digital 10-bit bi-directional bus. There are four modes:
Tri-state: when OEB = 1
Output ten-bit: ten bit data is output from bus
Output 8-bit multiplexed: data output on OP[9:2] at 2*ADC conversion rate
Input 8-bit: control data is input on bits OP[9:2]
