TDA4691 - Sync Processor

Description

The TDA4691 is a bipolar integrated circuit for sync processing in 50/100 and 60/120 Hz TV sets, preferably in conjunction with the programmable deflection controller TDA9150.

Features

  • Sync processor for horizontal (H) and vertical (V) sync pulses generated by internal 13.5 MHz oscillator.
  • Stable ‘On Screen Display (OSD)’, if no input signal is present with free running internal oscillator; automatic turn over to locked oscillator, if input signal is available.
  • External clock oscillator can be used.
  • Standard 50/60 Hz signals are identified automatically.
  • Additional outputs for 13.5 MHz, composite sync, 50//60 Hz identification, sig.
