Ordering number : ENN5743B

CMOS IC

LC72137, 72137M

PLL Frequency Synthesizer

for Electronic Tuning

Overview

The LC72137 and LC72137M are high input sensitivity

(FMIN: 10 mVrms at 130 MHz) PLL frequency

synthesizers for 3 V systems. They allow high-

performance AM/FM tuners to be implemented easily.

• Operating ranges

— Supply voltage: 2.5 to 3.6 V

— Operating temperature: –20 to +70°C

• Packages

—DIP22S/MFP20

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.

• CCB is a trademark of SANYO ELECTRIC CO., LTD.

• CCB is SANYO’s original bus format and all the bus

addresses are controlled by SANYO.
