Description

This multistandard video IF processing circuit with PLL picture carrier regeneration gives a high performance of linear video demodulation.

Features

Suitable for standard B/G, L and D2MAC, processes negative and positive modulated IF-signals with equal

polarity of the output signal

High performance video demodulator with PLL picture carrier regeneration

Extended video bandwidth (12 MHz) for the demo dulation of amplitude modulated MAC-signals

Standard B/G: AGC acting on the sync peak pulse

Standard L: fast AGC acting on peak white level with average value controlled capacitor discharge and

reference hysteresis

D2MAC: fast AGC acting on peak level with controlled capacitor discharge

Output for delayed tuner-AGC, take over point adjustable

High input sensitivity

Ultra white and ultra black limiting

Supply voltage range 6.8 to 13 V

Low power consumption

ESD protection

Application

Monolithic integrated circuit for vision IF signal processing in multistandard TV and VTR sets.
