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
