MOS INTEGRATED CIRCUIT
µPD1723GF-013, µPD1723GF-213
PLL FREQUENCY SYNTHESIZER AND CONTROLLER
FOR FM/MW/LF TUNER (CAR AUDIO)
The µPD1723GF-013 and µPD1723GF-213 are CMOS LSI developed for worldwide PLL frequency synthesizer
FM/MW/LW tuner use.
Their package is a 64-pin QFP. On-chip PLL frequency synthesizer, controller, 200 MHz prescaler, LCD driver,
and IF counter allow the construction of a compact FM/MW/LW tuner with a high-performance clock for high-
end car stereo and home stereo sets.
