TDA4455 Datasheet (TEMIC Semiconductors) - Multistandard VIF Amplifier and PLL Demodulator

TDA4455, Multistandard VIF Amplifier and PLL Demodulator

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

With two IF inputs (Pins 1 *2 and Pins 17 *18), it is possible to select between two signal sources.

The input selector switch (Pin 16) works inde
