3.6 S tereo Audio Interfac e
The main features of the interface are:
Stereo and mono analogue input for voice band and audio band
Stereo and mono analogue output for voice band and audio band
Support for stereo digital audio bus standards such as I2S
Support for IEC-60958 standard stereo digital audio bus standards i.e.
S/PDIF and AES3/EBU
Support for PCM interfaces including PCM master CODECs that require
an external system clock
3.7 PCM CODEC Interfac e
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
