NOTES: A. The video-processing (off-chip) pulses are defined as follows:

CL1 = Clamp pulse for video from OUT1

SH1 = Sample pulse for the sample-and-hold amplifier for video 1

CL2 = Clamp pulse for video from OUT2

SH2 = Sample pulse for the sample-and-hold amplifier for video 2

CL3 = Clamp pulse for video from OUT3

SH3 = Sample pulse for the sample-and-hold amplifier for video 3

B. The signals for channel (n+1) are phase shifted 120

° from the signals for channel (n). For example, SRG2 is phase shifted

120

° relative to SRG1, SRG3 is phase shifted 120° relative to SRG2, OUT2 is phase shifted 120° relative to OUT1, OUT3 is

phase shifted 120

° relative to OUT2, and so forth.
