2.2 Input signal amplitude

TC90101FG has a 10bit ADC for CVBS & Y signal and 2ch 8bit ADC for C & Cb/Cr.

The Dynamic range of ADC is desgned as AVDD *0.4 (Normally 1Vpp at AVDD = 2.5V).

The recomemdation amplitude of the input signal : 0.7Vpp at 140IRE (CVBS/Y) . refer to fig-1.

* in case of AGC ON, recommendation input signal amplitude is 0.6Vpp (140IRE).

(AGC control range is from - 6dB to +3dB.)
