TDA4560 Datasheet | NXP Semiconductors

DESCRIPTION The TDA4560 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 720 ns to 1035 ns in steps of 45 ns - Output for the option of velocity modulation QUICK REFERENCE DATA Supply voltage (pin 10) Supply current (pin 10) (R-Y) and (B-Y) attenuation (R-Y) and (B-Y) output transient time Adjustable Y-delay time Y-attenuation PACKAGE OUTLINE 18-lead DIL; plastic (SOT102); SOT102-1; 1996 November 27.

Philips Semiconductors Product specification Colour transient improvement circuit FUNCTIONAL DESCRIPTION The IC consists of two colour difference channels (B-Y) and (R-Y) and a luminance signal path (Y) as shown in Fig.1. Colour difference channels The (B-Y) and (R-Y) colour difference channels consist of a buffer amplifier at the input, a switching stage and an output amplifier. The switching stages, which are controlled by transient detecting stages (differentiators), switch to a value that has been stored at the beginning of the transients. The differentiating stages get their signal direct from the colour difference detecting signal (pins 1 and 2). Two parallel storage stages are incorporated in which the colour difference signals are stored during the transient time of the signal. After a time of about 600 ns they are switched immediately (transient time of...
