Bluetooth Transmit Data Module
Shanghai Ehong Technologies Inc
It supports 13-bit or 16-bit linear, 8-bit µ-law or A-law companied sample formats at 8k
samples/s and can receive and transmit on any selection of three of the first four slots following
PCM_SYNC.
The module interfaces directly to PCM audio devices including the following:
 Qualcomm MSM 3000 series and MSM 5000 series CDMA baseband devices
 OKI MSM7705 four channels A-law and µ-law CODEC
 Motorola MC145481 8-bit A-law and µ-law CODEC
 Motorola MC145483 13-bit linear CODEC
 STW 5093 and 5094 14-bit linear CODECs
 The module is also compatible with the Motorola SSI™ interface.
