can be achieved. If the transmit power amplifier is not in use, it can be powered down by connecting
PAI to V
The power supply for the analog and digital parts of the W681513 must be 5V +/- 10%. This supply
voltage is connected to the V
ceramic capacitor.
The analog ground reference voltage is available for external reference at the V
needs to be decoupled to V
The PCM interface is controlled by pins BCLKR, FSR, BCLKT & FST. The input data is received
through the PCMR pin and the output data is transmitted through the PCMT pin. The modes of
operation of the interface are shown in Table 7.3.
The Long Frame Sync or Short Frame Sync interface mode can be selected by connecting the
BCLKR or BCLKT pin to a 2.000 MHz clock and connecting the FSR or FST pin to the 8 kHz frame
sync. The device synchronizes the data word for the PCM interface and the CODEC sample rate on
the positive edge of the Frame Sync signal. It recognizes a Long Frame Sync when the FST pin is
