Colour transient improvement circuit TDA4565

GENERAL DESCRIPTION

The TDA4565 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 730 ns to 1000 ns in steps of 90 ns and additional fine adjustment of 50 ns

• Two Y output signals; one of 180 ns less delay

QUICK REFERENCE DATA

Note

1. Delay time is proportional to resistor R

.

R

also influences the bandwidth; a value of 1.2 kΩ results in a bandwidth of 5 MHz (typ.).
