NOTES
1R, G, and B signals are inputted via an external ac coupling capacitor.
2Except during dc restore period (back porch clamp).
3All outputs measured at a 75
reverse-terminated load; ac voltages at the IC output pins are twice those specified here.
4Difference between ideal and actual color bar subcarrier amplitudes.
5Difference between ideal and actual color bar subcarrier phases.
Specifications are subject to change without notice.
