Overview

The LC72151V is a PLL frequency synthesizer for car

audio systems. It can implement high-performance

multifunction tuners such as RDS tuners and features a

fast locking circuit.

Functions

• High-speed programmable divider

— FMIN: 10 to 160 MHz: Pulse swallower type

— AMIN: 2 to 40 MHz: Pulse swallower type

0.5 to 10 MHz: Direct division type

• IF counter

— HCTR: 0.4 to 25 MHz: for FM IF count

— LCTR: 10 to 500 kHz: for AM IF count

1.0 to 20

measurement

• Reference frequency

— One of 11 frequencies may be selected (when a

10.25 or 10.35 MHz crystal is used)

Note: Cannot be used when a 10.25 MHz crystal is

used

• Phase comparator

— Supports dead band control

— Built-in unlock detection circuit

— Built-in deadlock clearing circuit

• Built-in amplifier for forming an active low-pass filter

— Built-in operational amplifier for FM high-speed

locking

— Built-in MOS transistor for AM tuning

• Built-in crystal oscillator output buffer

• I/O ports — General-purpose I/O: 2 pins

— Four input ports (maximum)

— Three output ports (maximum)

• Serial data I/O

— Supports communication with the controller in the

CCB format.

• Operating ranges
