TDA9806 - Multistandard VIF-PLL and FM-PLL demodulator

Description

The TDA9806 is an integrated circuit for multistandard vision IF signal processing and FM sound demodulation in TV and VCR sets.

Features

  • 5 V supply voltage.
  • 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).
  • Separate video amplifier for sound trap buffering with high video bandwidth.
  • VIF AGC detector for gain control, operating as peak sync detector for B/G.
  • Tuner AGC with adjustable takeover point (TOP).
