LM1391 Datasheet Lm1391 Phase-locked Loop

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM1391 Phase-Locked Loop February 1995 LM1391 Phase-Locked Loop General.

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 applications It includes a stable VCO linear pulse phase detector and variable duty cycle output driver Y Y Y Y Y

Key Features

  • Y Y Y Y Y Internal active regulator for improved supply rejection Uncommitted collector of output transistor Output transistor with low saturation and high voltage swing APC of the oscillator with a synchronizing signal DC controlled output duty cycle g 300 Hz typical pull-in Linear balanced phase detector Low thermal frequency drift Small static phase error Adjustable DC loop gain Schematic Diagram TL H 7889.
  • 1 ( ) Pin 4 Base of Q16 (LM1391) for use with ( a ) flyback pulse C199.
