TDA4565 - NXP

TDA4565 Colour transient improvement circuit

TDA4565 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 diff.

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 PARAMETER Supply voltage (pin 10) Supply current (pin 10) Y-signal delay at pin 12 V15-18 = 0 to 2.5 V V15-18 = 3.5 .
