LM1391 Phase-Locked Loop

General Description

Output transistor with low saturation and high voltage

swing

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.

APC of the oscillator with a synchronizing signal

DC controlled output duty cycle

300 Hz typical pull-in

Linear balanced phase detector

Low thermal frequency drift

Small static phase error

Features

Internal active regulator for improved supply rejection

Uncommitted collector of output transistor

Adjustable DC loop gain
