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))

DESCRIPTION
OUTPUT
TYPE
The FM local oscillation output (VCO output) is input
to this pin.
When the radio is turned on and the FM band is
received, this pin becomes active. Otherwise, it is
pulled down internally.
The input amplitude is 0.3 VP-P MIN.
Since there is an on-chip AC amplifier, block the DC
component of the input signal with a capacitor.
Input
Device select signal input pin.
When the device is operated normally (radio, tape, CD,
clock display, etc.), High level is input and when the
device is not used, Low level is input.
However, High and Low levels of 134 µs or less are not
accepted.
When this pin is Low level, the radio, tape, CD, and
display are turned off and the device enters the data
hold state.
At this time, data hold at low consumption current (400
nA or less) is possible by setting the NOCLK switch of
the diode matrix to be described later to 1 (shorted by
diode, no-clock mode).
Input
Radio mode AGC (AUTOMATIC GAIN CONTROL) cut
signal output pin.
During autotuning, the High level shown below is
output.
