W681310
7.3.1. Analog and Digital Supply
The power supply for the analog and digital parts of the W681310 must be 2.7V to 5.25V. This supply
voltage is connected to the V
DD
pin. The V
DD
pin needs to be decoupled to ground through a 0.1
渭F
ceramic capacitor.
7.3.2. Analog Ground Reference Bypass
The system has an internal precision voltage reference which generates the V
DD
/2 mid-supply analog
ground voltage. This voltage needs to be decoupled to V
SS
at the V
REF
pin through a 0.1
渭F
ceramic
capacitor.
7.3.3. Analog Ground Reference Voltage Outpt
The analog ground reference voltage is available for external reference at the V
AG
pin. This voltage
needs to be decoupled to V
SS
through a 0.01
渭F
ceramic capacitor. The analog ground reference
voltage is generated from the voltage on the V
REF
pin and is also used for the internal signal processing.
7.4. PCM I
NTERFACE
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.
