Notes
1) This is the IC supply current value.
2) Measure the output voltage level when no signal input.
3) Measure the output signal peak-to-peak voltage level when the input signals are following level (peak-topeak voltage).
±R-Y signal 525mVp-p
±B-Y signal 665mVp-p
4) Gnt means the ratio of Output/Input signal when NTSC, PAL signal input.
Gseca means the ratio of Output/Input signal when SECAM signal input.
Signal wave form of NTSC/PAL and SECAM are shown in following.
5) Measure the noise voltage at f = 10kHz to 1MHz, and no signal input.
6) Measure the Signal to Noise ratio at f = 10kHz to 1MHz, and output signal = 1Vp-p.
