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), NR

Auto preset memory function

” (Compact Disk) display

LOUD (LOUDNESS) control output and display

(NOISE REDUCTION), NR , and AMS (AUTO MUSIC SEARCH) 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))
