Pin Name
Pin No.
Function
This pin inputs local oscillation output (VCO output) of FM
band. It becomes active when FM band is received; oth-
erwise, it is internally pulled down.
Input frequency ranges from 15 to 150 MHz (0.3 V
p-p
). Because
on-chip AC amplifier is provided, cut out DC component
with a capacitor.
Ground pins.
GND
0
is ground of PLL, and GND
1
and GND
2
are grounds
of digital circuits.
Connect nothing to this pin.
These are output pins of charge pump of PLL (Phase
Locked Loop). If divided local oscillation frequency (VCO
output) is higher than reference frequency, these pins
output high level; if local oscillation frequency is lower
than reference frequency, these pins output low level.
They are floated if two frequencies match.
These outputs are input to external LPF (lowpass filter) and
are applied to varactor diode via LPF.
Same waveform is output to EO
0
and EO
1
. You can use
either pin.
These pins indicate operation mode of

SK mute output pin used in absence of traffic information
station identification signal in TP/SK mode.
Sound mute signal output pin.
It is used to reject shock noise that is generated when PLL
is unlocked in radio mode, or to select mode pin output.
For output timing, refer to 7. MUTE OUTPUT TIMING
CHART.
Traffic information station identification signal output pin.
It goes low when:
SK or DK signal, TP or TA bit, or alarm is detected in TP/
SK mode of FM band.
Traffic information alarm is output.
Connect nothing to this pin.
