TDA4691 Product details

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.
