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

● Two IF-inputs, for switching between two signal sources (e.g., two tuners and two SAW-filters)

● High performance video demodulator with PLL picture carrier regeneration

● Extended video bandwidth (12 MHz) for the demodulation 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.
