Preliminary specification
Colour transient improvement circuit
TDA4566
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
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
QUICK REFERENCE DATA
Note
1.
Delay time is proportional to resistor R
14-18
.
R
14-18
also influences the bandwidth; a value of 1.2 k
results in a bandwidth of 5 MHz (typ.).
