TDA4454 Datasheet (TEMIC Semiconductors) - Multistandard VIF Amplifier and PLL Demodulator

TDA4454, 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.

The IF signal is internally fed via a 3-stage controlled wideband amplifier to the video demodulator and the phase detector.

The phase detector compares the pha
