TDA4691 Datasheet (NXP) - Sync Processor

TDA4691, Sync Processor

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.

A line locked 13.5 MHz clock with several dividers and logic circuitry is available generating the horizontal and vertical s

TDA4691 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
