Ordering number : EN5743
CMOS IC
LC72137, 72137M
PLL Frequency Synthesizer
for Electronic Tuning
Overview
The LC72137 and LC72137M are PLL frequency
synthesizers for use in radio/cassette players. They allow
high-performance AM/FM tuners to be implemented
easily.
Features
• High-speed programmable frequency divider
— FMIN: 10 to 160 MHz.....Pulse swallower
(divide-by-two prescaler built in)
— AMIN: 2 to 40 MHz.........Pulse swallower
0.5 to 10 MHz......Direct division
• IF counter
IFIN: 0.4 to 12 MHz................For use as an AM/FM IF
counter
• Reference frequency
— Selectable from one of eight frequencies (crystal
oscillator: 75 kHz)
1, 3, 5, 3.125, 6.25, 12.5, 15, and 25 kHz
• Phase comparator
— Supports dead zone control
— Built-in unlock detection circuit
— Built-in deadlock clear circuit
• Built-in MOS transistor for forming an active low-pass
filter
• I/O ports
— Dedicated output ports: 4
— I/O ports: 2
— Supports clock time base output
• Serial Data I/O
— Supports CCB format communication with the
system controller.
