(2) The color subcarrier should have a duty of 50%. Duty fluctuation will affect chroma phase. Resistance- splitting input is used in the "Application example" to accommodate 5VP-P CMOS input. For other types of input, adjust to 0.5VP-P at SCIN. (3) Composite synch and burst flag pulse inputs should conform to their respective standards, as improper tim- ing between them can prevent the TV from displaying color images. For input, use the TTL level and an impedance of 8k Ω. |
