Overview
The LC72146 is a PLL frequency synthesizer LSI circuit
for electronic tuning in car stereo systems. The LC72146
supports the construction of high-performance, multi-
functional electronic tuning systems for the VHF MW,
and LW bands.
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 1.0 Hz to 20
× 103 kHz period measurement
Reference frequencies: Twelve selectable reference
frequencies (4.5 or 7.2 MHz crystal) 1, 3, 5, 9, 10,
3.125, 6.25, 12.5, 25, 30, 50 and 100 kHz
Phase comparator
— Insensitive band control
— Unlock detection
— Sub-charge pump for high-speed locking
— Deadlock clear circuit
CCB input/output data interface
Power-on reset circuit
Built-in MOS transistor for a low-pass filter
Inputs/outputs (using five general-purpose input/output
ports)
— Maximum of seven inputs (max)
— Maximum of seven outputs (max/four n-channel
open-drain and three CMOS outputs)
— Time-base output for clock (8 Hz)
Operating ranges
— Supply voltage ..................................4.5 to 5.5 V
— Opetating temperature ......................–40 to 85
°C
Package
