Overview
INTEGRATED CIRCUITS DATA SHEET TDA4565 Colour transient improvement circuit Product specification File under Integrated Circuits, IC02 November 1989 Philips Semiconductors Product specification Colour transient improvement circuit GENERAL DESCRIPTION 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 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 to 12 V Y-signal attenuation (R-Y) and (B-Y) signal attenuation output transient time Note 1.
Delay time is proportional to resistor R14-18.
R14-18 also influences the bandwidth; a value of 1.
2 kΩ results in a bandwidth of 5 MHz (typ.
).
