2.2.1.1.2. PCM Audio
PCM audio interface to the host uses the following signals:
In Slave mode, input frequencies up to 16MHz supported. In master mode, the TI1283
can generate any clock frequency between 64KHz and 4.096MHz.

o BT_PCM_IN
o BT_PCM_SYNC
o BT_PCM_CLK
The BT Audio Codec has a fully dedicated programmable serial port
o Two voice channels
o Supports Master/slave modes
o u-law, a-law, linear and transparent coding schemes
o Long and short frames
o Different data sizes, order and positions
o UDI profile
o High rate PCM
2.2.2. Power Class
148603 supports up to Power Class 1.5 Operation.
2.2.3. 148603 BT RF Paths
The 148603 design will be the first internal module to integrate a PTA and selection
diversity antenna structure over the same RF paths. Due to the development cycle and
schedule, at the time of the release of the module‟s engineering design, this timing was
not fully understood. Consequently, the 148603 team designed in a provision that
would allow the BT RF to be available through a separate RF port. Should this
population option need to be used, external matching and filtering would be required
and support from the 148603 module team should be sought when implementing this
option.
 IMPORTANT NOTE: A tradeoff performance evaluation is currently being
conducted to demonstrate the ability to break-out the BT RF from the WL1283 to
the 148603 Module pins, bypassing the FEM and disabling PTA.
