Notes: •
IRE: Units for video amplitude; 0.714 V video level is specified as 100 IRE
4fsc and 2fsc must be adjusted within ± 30 ppm, including temperature dependency.
•
1. Bias from the sync tip clamp level (reference value after −6 dB).
2. Bias from the pedestal level (reference value after −6 dB).
3. At 4fsc input.
