Overview
The LC72191, LC72191M and LC72191JM are PLL frequency synthesizers for electronic tuning. The LC72191, LC72191M and LC72191JM are optimal for AM/FM tuner circuits that require high mounting densities.
Features
Designed for use in car stereos, the LC72191 provides a rich set of reference frequencies, I/O ports, a general purpose counter, and an unlock detection circuit.
Functions
• Programmable dividers
— FMIN pin: 130 MHz at 70 mVrms and 160 MHz at 100 mVrms input (built-in
prescaler)
— AMIN pin: Pulse swallower and direct division techniques
• Reference frequencies: Ten selectable frequencies:
1, 5, 9, 10, 3.125, 6.25, 12.5 25, 50 and 100 kHz
