TDA4455 Product details

Description

This multistandard video IF processing circuit with PLL picture carrier regeneration gives a high performance of linear video demodulation. 2 and Pins 17 18), it is possible to select between two signal sources.

Features

D Suitable for standard B/G, L and D2MAC, processes negative and positive modulated IF-signals with equal polarity of the output signal D Standard L: fast AGC acting on peak white level with average value controlled capacitor discharge and reference hysteresis D Two IF-inputs, for switching between two signal sources (e. g. , two tuners and two SAW-filters) D D2MAC: fast AGC acting on peak level with controlled capacitor discharge D Output for delayed tuner-AGC, take over point adjustable D H.
