Notes

1. Supply voltage rejection ratio = 20logV--V---R-R---(--(C--O-C--)--)-

2. The relative gain difference is measured when only one input signal (R, G or B) is present.

3. The inputs RIN, GIN and BIN are interconnected; ∆t is the maximum time coincidence error between the luminance

and the chrominance signals.
