GENERAL DESCRIPTION
TDA4568FEATURES
● 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 490 580 670 760 0 550 640 730 820 1 610 700 790 880 2 ns ns ns ns dB CONDITIONS VP IP SYMBOL − MIN. 10.8 TYP. 12 22 − MAX. 13.2 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 to 12 V Y-signal amplification Note 1. Delay time is proportional to resistor R14-18. R14-18 also influences the bandwidth; a value of 1.2 kΩ results in a bandwidth of 5 MHz (typ.).
