LC7219, 7219M
PLL Frequency Synthesizers
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.
(The IF signal count must be used together with the SD
(station detect) signal from IF-IC).
• 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.
