LM1291
Video PLL System for Continuous-Sync Monitors
General Description
The LM1291 is an integrated horizontal time base solution
specifically designed to operate in continuous-sync video
monitors It automatically synchronizes to any H frequency
from 22 kHz to 125 kHz and provides the drive pulse to the
high power deflection circuit
Available sync processing includes a vertical sync separator
and a composite video sync stripper An internal sync selec-
tion scheme gives highest priority to separate H and V sync
then composite sync and finally sync on video no external
switching between sync sources is necessary The LM1291
provides polarity-normalized HHV and V sync outputs
along with logic flags which show the respective input polar-
ities
The design uses an on-chip FVC (Frequency-to-Voltage
Converter) to set the center frequency of the VCO (Voltage-
Controlled Oscillator) This technique allows autosync oper-
ation over the entire frequency range using just one opti-
mized set of external components
The system includes a second phase detector which com-
pensates for storage time variation in the horizontal output
transistor the picture’s horizontal position is thus indepen-
dent of temperature and component variance
The LM1291 provides DC control pins for H Drive duty cycle
and flyback phase
