Pin name
Input pin for the modulation signal.
Input the signal as indicated in the table below.
Input pin for the CD changer data.
Input pin for the BATT signal.
Input the signal as indicated in the table below.
In no-clock mode (initial setting diode NOCLK = 1) or a mode in
which the clock is not counted during power off (initial setting diode
CTOFF = 1), the power consumption is reduced during power off.
Input pin for the ACC signal.
Input the signal as indicated in the table below.
In no-clock mode (initial setting diode NOCLK = 1) or a mode in
which the clock is not counted during power off (initial setting diode
CTOFF = 1), the power consumption is reduced during power off.
The input of a high-level signal indicates that the front panel has
been detached.
Remote-controller signal input pin.
RDS clock input pin. To this pin, input the clock signal from the
RDS signal detector section.
Because the PD178016GC-051 does not detect bit
synchronization based on the width of a clock signal, the input
clock signal must be as accurate as possible.
Input pin for RDS data. To this pin, input the data signal from the
RDS signal detector section.
Data is read at the falling edge of an RDS clock pulse.
Regulator pin for CPU power supply.
Connect this pin to ground via a 0.1- F capacitor.
