RDSDATA
RDS data input
RDS data input pin. Input data signal from RDS signal
detection block.
Data is read at falling edge of RDS clock.
RDS
RDS signal
input
Input pin to detect RDS signal of RDS station. Used to
prevent synchronization caused by station other than an
RDS station.
Input RDS data is valid when this pin is low.
To synchronize with RDSDATA and RDSCLK only during
auto tuning operation, pull down this pin.
RDSCLK
RDS clock
input
RDS clock input pin. Input clock signal from RDS signal
detection block.
Because the µPD17006AGF-011 does not detect bit syn-
chronization by width of clock signal, input as accurate a
clock as possible.
Band select signal output pins.
When received band is changed by band select key, output

Device power supply pins.
Supply 5 V ± 10 % to these pins when device operates.
When timer is not used (when NOCLK switch of initial

VDD1
Power inputs pins is lowered to 2.2 V, data can be retained if CE pin (pin

31) is made low. If 0 to 4.1 V is supplied to these pins, data
is initialized to initial value. At this time, keep time of
raising voltage from 0 to 4.1 V within 500 ms.
Be sure to connect VDD0 to VDD2 pins to same voltage.
This pin inputs local oscillation output (VCO output) of AM
(MW, LW) band.

be input are 0.5 to 25 MHz (0.3 Vp-p). Because on-chip AC
amplifier is provided, cut out DC component with capacitor.
