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.
FEATURES
• Worldwide FM/MW banks and European LW band can be received.
• Abundant tuning functions, including manual tuning, autotuning (seek, scan), and preset memory scan
• Six buttons, independent preset memories for 18 FM stations (FM1, FM2, FM3; 6 stations each), 12 MW
stations (MW1, MW2; 6 stations each), 6 LW stations, and VF band
• FM: 3, MW: 2, LW: 1, VF: 1 last channel memories
• VF broadcast station (traffic information) autotuning (SK signal search) and DK standby function
• MONO (MONORAL) and LOC (LOCAL/DX) control output and display
• “ST” (STEREO) display
• MTL (METAL), NR1 (NOISE REDUCTION), NR2, and AMS (AUTO MUSIC SEARCH) control output and display
• Auto preset memory function
• “ ” (Compact Disk) display
• LOUD (LOUDNESS) control output and display
• 12 hour and 24 hour clock display function (no clock display also possible)
• Single 5 V ±10 % power supply
• On-chip prescaler (200 MHz max. Vin = 0.3 VP-P), IF counter, LCD driver (1/2 duty, 1/2 bias drive, frame frequency
(100 Hz))
