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.
