Overview

The LC7219 and LC7219M are high-performance, phase-

locked loop (PLL) frequency synthesizer ICs that operate

over the AM and FM radio wavebands. They feature excel-

lent frequency tracking, making them ideal as reference

frequency sources for use in AM/FM tuners, television and

audio-video equipment, and high-quality car-stereo appli-

cations.

The LC7219 and LC7219M operate from a 5 V supply and

are available in 24-pin DIPs and 24-pin MFPs, respectively.

Features

• Programmable divider.

• General-purpose universal counter.

• Unlock detector.

• 8 Hz real-time clock output.

• Ten selectable reference frequencies.

• 400 kHz microcontroller system-clock output.

• Swallow counter.

• Shift register.

• 5 V supply.

• 24-pin DIP and 24-pin MFP.

Ordering number:ENN3661B
