NOTES
1Difference between ideal and actual color-bar subcarrier amplitudes.
2Difference between ideal and actual color-bar subcarrier phase.
3Current consumption is larger in standard termination mode. Current values shown for 50% average picture level. Larger current consumption possible for other levels.
