FEATURES
GENERAL 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. A line
locked 13.5 MHz clock with several
dividers and logic circuitry is available
generating the horizontal and vertical
sync outputs. The device can be
assembled in a DIL20 or SO20
package.
September 1993
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, signal identification
(mute), super-sandcastle 12 V
TTL compatible outputs (H, V,
composite sync and 13.5 MHz)
3 different time constants for the
PHI1 PLL: fast, normal and slow
(T
time constant are set independent
from each other
Start of H-pulse definable by
application
Digital interference reduction for H
and V signals
Digital noise detector
Time correction of non-standard
H-pulses and equalizing pulses for
optimum PLL control.
