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.)
