GENERAL DESCRIPTION
The TDA4566 is a monolithic integrated circuit for colour-transient improvement (CTI) and luminance delay line in gyrator
technique in colour television receivers.
Features
QUICK REFERENCE DATA
Note
1. Delay time is proportional to resistor R
PACKAGE OUTLINE
18-lead DIL; plastic (SOT102); SOT102-1; 1996 November 27.
March 1991
Supply voltage (pin 10)
Supply current (pin 10)
Y-signal delay at pin 12
Y-signal amplification
(R-Y) and (B-Y) signal
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 550 ns to 820 ns in steps of 90 ns and additional fine adjustment of 37 ns
Two Y output signals; one of 180 ns less delay
