HUAWEI LGA Module PCM Audio Design Guide

Introduction

Introduction
The purpose of this document is to describe some hardware specification which is
useful to develop a product with Huawei LGA module supporting PCM (Pulse-Coded
Modulation). This document is intended for customers who are integrators and about
to implement their applications by using Huawei LGA module.
Huawei LGA module supports the PCM, which can be used for the module to
transmit and receive digital audio data, and uses the PCM interface as part of the
audio front end; therefore an external codec is easily allowed to be used instead of
the internal codec. For example, through the PCM you could connect Huawei LGA
module to a Bluetooth device.
Huawei LGA module has one PCM port. Please refer to the hardware guide of the
module that you are in use to know the pin number of the PCM port.
