TEA-566A

The TEA566A is designed as one kind of color TV PAL decoder that combines all functions required for the identification and demodulation of PAL signal. Features of this device are:(1)phase locked reference oscillator;(2)U and V axis decoders;(3)ACC and identification detectors;(4)killer;(5)use of a sandard 4.43 MHz Xtal;(6)compatibility with the SECAM decoder TEA5630 for PAL-SECAM application.

The absolute maximum ratings of the TEA566A can be summarized as:(1)supply voltage: 14.4 V;(2)power dissipation: 800 mW;(3)operating ambient temperature: 0 to 70 ;(4)storage temperature: -55 to +150 ;(5)junction ambient thermal resistance: 70 /W.

The electrical characteristics of this device can be summarized as:(1)operating supply voltage: 10 to 14.4 V;(2)supply current: 40 mA to 52 mA;(3)DC voltage, with sample pulse to pin 17, at pin 2 to pin 3:4.3 V to 5.3 V;(4)sampling pulse threshold: 0 to 0.8;(5)line retrace threshold: 2.5 V;(6)phase hold characteris-tics: 0.03 /Hz;(7)pull-in frequency range: +/- 800 Hz.
