TDA9815 - Multistandard/MAC VIF-PLL with QSS-IF and dual FM-PLL/AM demodulator

Description

The TDA9815 is an integrated circuit for multistandard vision IF signal processing (inclusive MAC) and sound AM and dual FM demodulation, with single reference QSS-IF in TV and VCR sets.

Features

  • 5 V supply voltage.
  • Two switched VIF inputs, gain controlled wide band VIF-amplifier (AC-coupled).
  • True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures, reduced harmonics, excellent pulse response).
  • Robustness for over-modulation better than 105% due to gated phase detector at L/L accent standard.
  • VCO frequency switchable between L and L accent (alignment external) picture carrier freq.
