Notes

1. Values of video and sound parameters can be decreased at VP = 4.5 V.

2. S/N is the ratio of the black-to-white amplitude to the black level noise voltage (RMS value) at pin CVBS.

B = 5 MHz weighted in accordance with “CCIR 567” at a source impedance of 50 Ω.

3. Measurements taken with SAW filter G1962; VSB modulation; fvideo > 0.5 MHz; loop bandwidth BL = 60 kHz.
