75 Ω VIDEO LINE DRIVER

FEATURES

■ Internal Y-C Summing Circuit

■ Internal Switch Circuit for Composite Signal or Y-C

Signal

■ Voltage Gain is 6 dB Fixed

■ Internal 75 Ω Driver

■ Very Small Output Capacitor Using SAG Function

Pin

■ Very Small Package (SOT23L-8)

DESCRIPTION

Operating from a single +5 V supply, the TK15414M 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 0 dB.)

APPLICATIONS

■ Video Equipment

■ Camcorder

■ CCD Cameras

■ DVD Player/RW

■ Video Board

■ Video Tape Recorders

■ LCD TV/Monitor
