Overview
TELEFUNKEN Semiconductors TDA4455 Multistandard VIF Amplifier and PLL Demodulator Application Monolithic integrated circuit for vision IF signal processing in multistandard TV and VTR sets.
Description 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 independent from the standard switch (Pin 11).
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 phase of IF...
