Pin name
Input pin for intermediate frequency (IF) in FM band.
To protect the built-in AC amplifier, use a capacitor to prevent the
flow of direct current.
When the FM SD/IF switch of the initial setting diode matrix is set
to 1 (the diode is jumpered), this pin is used to detect a station
during auto-tuning.
When the input frequency range and conditions listed below are
satisfied, the device judges that a station has been detected.
A frequency within the input frequency range must be input within
20 ms of the PLL being locked. However, input the frequency
within 5 ms during AF operation, best station, or EON operation.
Connect this pin to V
Input pin for the FM band local oscillator output (VCO output).
Tuning to FM band broadcasts causes this pin to become active.
Otherwise, the pin enters the high-impedance state.
To protect the built-in AC amplifier, use a capacitor to prevent the
flow of direct current before inputting the output.
Input pin for the local oscillator output (VCO output) in the AM
(MW, LW) band.
Tuning to MW or LW band broadcasts causes this pin to become
active. Otherwise, the pin enters the high-impedance state.
To protect the built-in AC amplifier, use a capacitor to prevent the
flow of direct current before inputting the output.
Ground pin for PLL.
Connect this pin to GND.
Insert a 100-pF capacitor between the V
Output pins for the PLL charge pump.
If a divided local oscillator frequency (VCO output) is greater than
the reference frequency, the outputs of these pins will go high. If
the divided local oscillator frequency is less than the reference
frequency, the outputs go low. If the divided local oscillator
frequency is equal to the reference frequency, the outputs enter the
floating state.
Input either of the outputs to a varactor diode via an external LPF
(Low Pass Filter).
Connect this pin to GND.
Input/output pin for exchanging serial data with the LCD controller/
driver ( PD16431A).
