LM1391 Phase-Locked Loop
General Description
The LM1391 integrated circuit has been designed primarily
for use in the horizontal section of TV receivers but may
find use in other low frequency signal processing applica-
tions It includes a stable VCO linear pulse phase detector
and variable duty cycle output driver
