Product specification

Fast RGB/YC switch for digital decoding

TDA8446

Notes

1. Supply voltage rejection ratio =

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.
