DATA SHEET
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.
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))
