W682510/W682310
7.2.2. PCMR1
The PCM signal input for channel 1 when in the parallel mode. D/A conversion is performed on the
serial PCM signal input to this pin. The FSR signal, synchronous with the serial PCM signal, and the
BCLK signal, processes the code. Then the analog output is output from the RO1 pin. The data rate of
the PCM signal is equal to the frequency of the BCLK signal.
The PCM signal is shifted in on the falling edge of the BCLK signal. It is latched into the internal 8-bit
register. The start of the PCM data (MSB) is synchronized with the rising edge of FSR. In the serial
mode, this pin is not used and should be connected to GND (0V).
7.2.3. PCMR2
PCM signal input for channel 2 when the parallel mode is selected. D/A conversion is performed with
the serial PCM signal input to this pin, the FSR signal, synchronous with the serial PCM signal, and
the BCLK signal, and then the analog output is output from the RO2 pin. The data rate of the PCM
signal is equal to the frequency of the BCLK signal. The PCM signal is shifted at the falling edge of the
BCLK signal and latched into the internal register when shifted by eight bits. The start of the PCM data
(MSB) is identified at the rising edge of FSR. In the serial mode this pin is used for the two channel
multiplexed PCM signal input.

7.3.1. V
DD
The power supply for the analog and digital parts of the W682510 must be 5V +/- 10% and 2.7V to
3.8V for the W682310. This supply voltage is connected to the V
DD
pin. The V
DD
pin needs to be
decoupled to ground through a 0.1
μ
F ceramic capacitor. A power supply for an analog circuit in the
system to which the device is applied should be used. A bypass capacitor of 0.1 μF to 1 μF with good
high-frequency characteristics (Low ESR) and a capacitor of 10 μF to 20 μF should be connected
between this pin and the V
SSA
pin if needed.
7.3.2. V
SSA
Ground for the analog signal circuits. This ground is separate from the digital signal ground. The V
SSA
pin must be connected to the V
SSD
pin on the printed circuit board to make a common ground.
However, it’s advised to connect the PCB traces of these pins at the main supply hookup of the PCB
and run the V
SSA
and V
SSD
traces separately to the device.
7.3.3. V
SSD
Ground for the digital signal circuits. This ground is separate from the analog signal ground. The V
SSD
pin must be connected to the V
SSA
pin on the printed circuit board to make a common ground.
However, it’s advised to connect the PCB traces of these pins at the main supply hookup of the PCB
and run the V
SSA
and V
SSD
traces separately to the device
