LM1391 Phase-Locked Loop Analogue TV IC PDIP-8

LM1391 Phase-Locked Loop Analogue TV IC PDIP-8

The LM1391 Phase-Locked Loop Analogue TV IC PDIP-8 is a purpose-designed phase-locked loop device that integrates a low-drift, stable voltage-controlled oscillator (VCO), a linear pulse phase detector, and a variable-duty-cycle output driver with an internal active regulator, intended primarily for television horizontal timing and other low-frequency signal-processing tasks in a PDIP-8 through-hole package.

Features

• Integrated stable VCO with automatic phase control (APC) for reliable frequency locking.
• Linear balanced pulse phase detector for low static phase error performance.
• Internal active regulator for improved supply rejection and simplified power supply design.
• Variable duty-cycle output driver with uncommitted collector for flexible interfacing.
• Low thermal frequency drift and small static phase error for accurate timing.
• Adjustable DC loop gain to tailor loop dynamics and bandwidth.
• Typical pull-in ≈300Hz and hold-in up to ≈900Hz for robust lock behaviour.
• Supports sawtooth/flyback synchronization inputs for TV horizontal applications.

Specifications

Absolute Maximum Ratings

* For operation in ambient temperatures above 25°C, the device must be derated based on a 150°C maximum junction temperature and a thermal resistance of 120°C/W junction to ambient.
