INTEGRATED CIRCUITS DATA SHEET TDA4566 Colour transient improvement circuit Preliminary specification File under Integrated Circuits, IC02 March 1991 Philips Semiconductors Preliminary specification Colour transient improvement circuit GENERAL DESCRIPTION TDA4566 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 PARAMETER Supply voltage (pin 10) Supply current (pin 10) Y-signal delay at pin 12 S1 open; R14-18 = 1.2 k; note 1 t17-12 t17-12 t17-12 t17-12 0.5 MHz Y cd ttr 490 580 670 760 0 -1 - 550 640 730 820 1 0 100 610 700 790 880 2 +1 200 ns ns ns ns dB dB ns CONDITIONS VP IP SYMBOL - MIN. 10.8 TYP. 12 35 MAX. 13.2 50 UNIT V mA V15-18 = 0 to 2.5 V V15-18 = 3.5 to 5.5 V V15-18 = 6.5 to 8.5 V V15-18 = 9.5 to12 V Y-signal amplification (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 k results in a bandwidth of 5 MHz (typ.).
