Description
Positive supply voltage (+ 5 V)
Push-pull outputs for directly driving the TV-SAM
chrominance inputs:
8 bits for 4:2:2 format;
4 bits for 4:1:1 format;
[UVQ0 … UVQ3 only valid for 4:2:2 format]
Ground (0 V)
Back-channel inputs for chrominance data from TV-SAM
Back-channel inputs for luminance data from TV-SAM
Data inputs for chrominance data accept the dig. YUV
signal
Data inputs for luminance data accept the dig. YUV
signal
Data-request input; initiates data transfer in multi-picture
mode and switches mode together with signal VS1
Ground (0 V)
Input for line-synchronous blanking signal that
determines line blanking interval (active low) and
synchronizes clock and sequence control
Input for line-locked system clock, 13.5 MHz, from which
internal timing is derived. Positive edge indicates validity
of input data
Must be connected to
Input for line-locked 13.5-MHz clock that ensured picture
stability in multi-picture mode and is used as output clock
in every mode
