PLL Frequency Synthesizer
for Electronic Tuning
LC72146, 72146M
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
×
