LC72191, 72191M, 72191JM
PLL Frequency Synthesizer
for Electronic Tuning in Car Stereo Tuners
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
• Output ports: 7 pins
Complementary outputs: 2 pins
N-channel open drain outputs: 5 pins
• Input ports: 2 pins
• General-purpose counter: For measuring IF and other
signals (Also used for station detection when
functioning as an IF counter.)
— HCTR pin: Frequency measurement (for inputs up to
70 MHz)
— LCTR pin: Frequency and period measurement
• PLL unlock detection circuit
Detects phase differences of 0.55, 1.11, 2.22 and 3.33 µs.
