Product specification

TDA4560

GENERAL DESCRIPTION

The TDA4560 is a monolithic integrated circuit for colour transient improvement (CTI) and luminance delay line in gyrator

technique in colour television receivers.

Features

• Colour transient improvement for colour difference signals (R-Y) and (B-Y) with transient detecting-, storage- and

switching stages resulting in high transients of colour difference output signals

• A luminance signal path (Y) which substitutes the conventional Y-delay coil with an integrated Y-delay line

• Switchable delay time from 720 ns to 1035 ns in steps of 45 ns

• Output for the option of velocity modulation
