Features

RGB encode
•LPF for chroma difference signal is built-in. Cutoff frequency control is possible by connecting a resistor externally.
•Because VCA circuit is built-in, gain control at chroma block is possible.
•Carrier leak is on a low level because of built-in high-precision modulation circuit and clamp circuit.
•Burst signal and sync signal are generated within the IC. Superimpose function
•Ys IN (control input) is used for switching 2 input signals, VIDEO IN and RGB IN.
•Because high-speed analog switch is built-in, even microscopic characters can be inserted.
•Built-in an APC circuit to adju.
