F1C28 Bluetooth Module has a digital audio interface that can be configured as a PCM or I²S support.
3.4.1 PCM Configuration
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
F1Q28 has a digital audio interface that can be configured as a PCM port.
The audio PCM interface on the F1Q28 supports:
■ Continuous transmission and reception of PCM encoded audio data over Bluetooth.
■ Processor overhead reduction through hardware support for continual transmission and reception of PCM data
■ A bidirectional digital audio interface that routes directly into the baseband layer of the firmware. It does not pass through the HCI
protocol layer.
■ Hardware on the F1Q28 for sending data to and from a SCO connection.
■ Up to 3 SCO connections on the PCM interface at any one time.
■ PCM interface master, generating PCM_SYNC and PCM_CLK.
■ PCM interface slave, accepting externally generated PCM_SYNC and PCM_CLK.
■ Various clock formats including:
■ Long Frame Sync
■ Short Frame Sync
■ GCI timing environments
■ 13-bit or 16-bit linear, 8-bit µ-law or A-law commanded sample formats.
■ Receives and transmits on any selection of 3 of the first 4 slots following PCM_SYNC.
