7.3. POWER MANAGEMENT
7.3.1. Analog and Digital Supply
The power supply for the analog and digital parts of the W681511 must be 5V +/- 10%. This supply
voltage is connected to the VDD pin. The VDD pin needs to be decoupled to ground through a 0.1 μF
ceramic capacitor.
7.3.2. Analog Ground Reference Voltage Outpt
The analog ground reference voltage is available for external reference at the VAG pin. This voltage
needs to be decoupled to VSS through a 0.01 μF ceramic capacitor.
7.4. PCM Interface
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.

Table 7.3 PCM Interface mode selections
7.4.1. Long Frame Sync
The Long Frame Sync or Short Frame Sync interface mode can be selected by connecting the
BCLKR or BCLKT pin to a 64 kHz to 4.096 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 held high for two consecutive falling edges of the bit-clock at the BCLKT pin. The length
of the Frame Sync pulse can vary from frame to frame, as long as the positive frame sync edge
occurs every 125
μsec. During data transmission in the Long Frame Sync mode, the transmit data pin
PCMT will become low impedance when the Frame Sync signal FST is high or when the 8 bit data
word is being transmitted. The transmit data pin PCMT will become high impedance when the Frame
Sync signal FST becomes low while the data is transmitted or when half of the LSB is transmitted. The
internal decision logic will determine whether the next frame sync is a long or a short frame sync,
based on the previous frame sync pulse. To avoid bus collisions, the PCMT pin will be high
impedance for two frame sync cycles after every power down state. More detailed timing information
can be found in the interface timing section.
