11. PCM Interface
Pulse Code Modulation (PCM) is a standard method used to digitize human voice
patterns for transmission over digital communication channel. Through its PCM
interface, MD-7EM has hardware support for continual transmission reception of PCM
data, thus reducing processor overhead for wireless application. MD-7EM offers a Bi-
directional digital audio interface that route directly into the baseband layer of the
Module firmware. It does not pass through the HCI protocol layer.
Hardware on MD-7EM allows the data to be sent to the received from a SCO
connection.
MD-7EM can be configured as PCM interface Master generating an output clock of
128, 256 or 512KHz. When configured as PCM interface slave it can operated with
input clock up to 2048KHz. MD-7EM is compatible with a variety of clock formats,
including Long Frame Sync, Short Frame Sync and GCI timing environments.
It supports 13-bit or 16-bit liner, 8-bit u-law or A-law companied sample formats at
8K samples/s and can receive and transmit on any selection of the first four slots
following PCM_SYNC.
