DESCRIPTION
TK15415
Operating from a single +5 V supply, the TK15415M is a
75 Ω video line driver IC with an internal Y-C summing
circuit. It has an internal switch circuit for the CVBS
compostie signal and the Y-C signal. The internal 1.5 k
SAG function resistor provides gain compensation for low
frequency signals. (Voltage gain from the CVBS signal
input terminal is 6 dB.)
