PLL Frequency Synthesizer
CMOS LSI
Overview
The LC72144M is an electronic tuning PLL frequency
synthesizer for use in car and home products, and allows
high-performance multifunction tuners to be implemented
easily, since it includes an A/D converter, a high-speed
lockup circuit, and a crystal oscillator circuit that support
AM up-conversion.
Features
High-speed programmable dividers for
— 10 to 160 MHz on FMIN using pulse swallower
— 0.5 to 40.0 MHz on AMIN using pulse swallower
and direct division
General-purpose counters
— HCTR for 0.4 to 25.0 MHz frequency measurement
— LCTR for 10 to 500 kHz frequency measurement
and 4.0 Hz to 20
× 103 Hz period measurement
4.5, 7.2, 10.25 or 10.35 MHz crystal
Twelve selectable reference frequencies (1, 3*2, 5, 9*2,
10, 3.125, 6.25, 12.5, 25, 30*2, 50 and 100*1 kHz)
Note: 1. Not supported when a 10.35 or 10.25 MHz
crystal oscillator is used.
2. Not supported when a 10.25 MHz crystal
oscillator is used.
Phase comparator
— Insensitive band control
— Unlock detection
— Sub-charge pump for high-speed locking
— Deadlock clear circuit
A/D converter: 6 bits, 2 inputs
Serial data input and output
Supports control and communication in the CCB format
Power-on reset circuit
On-chip crystal oscillator output buffer
Inputs/outputs (using six general-purpose input/output
ports)
Operating ranges
— Power-supply voltage: 4.5 to 5.5 V
— Operating temperature: –40 to 85°C
Package: MFP24S
Package Dimensions
unit: mm
3112-MFP24S
