NXP Semiconductors TDA4566
The TDA4566 is a monolithic integrated circuit for colour-transient improvement (CTI) and luminance delay line in gyrator technique in colour television receivers.GENERAL DESCRIPTION
TDA4566FEATURES
● 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 kΩ; note 1 t17-12 t17-12 t17-12 t17-12 0.5 MHz αY αcd 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.
