3.4 PCM
Pulse Code Modulation (PCM) is a standard method used to digitize audio
(particularly voice) patterns for transmission over digital communication
channels. Through its PCM interface, this module has hardware support for
continual transmission and reception of PCM data, so reducing processor
overhead for wireless headset applications. This module offers a bi-directional
digital audio interface that route directly into the baseband layer of the on-chip
firmware. It dose not pass through the HCI protocol layer.
Hardware allows the data to be sent to and received from a SCO connection
This module interfaces directly to PCM audio devices including the following :
- Qualcomm MSM 3000 series and MSM 5000 series CDMA baseband devices
- OKI MSM7705 for channel A-law and u-law CODEC
- Motorola MC145481 8-bit A-law and u-law CODEC
- Motorola MC145483 13-bit linear CODEC
- STW 5093 and 5094 14-bit linear CODECs
3.4.1 PCM Configuration
The PCM configuration is set using two PS keys, PSKEY_PCM_CONFIG32 and
PSKEY_PCM_LOW_JITTER_CONFIG. The default for long frame sync and interface master generating
256KHz PCM_CLK with no tristating of PCM_OUT.
