TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
This guide explains how to make a dial up connection with Linux.
This document describes how electrostatic discharge (ESD) occurs, how to conduct ESD tests, how interfering signals resulted from ESD are coupled to circuits of electronic devices, and what rules need to be followed during ESD design for Huawei LGA modules. Following these rules can provide users with good ESD performance during applications of Huawei LGA modules.
This document describes the rules and precautions of designing Printed Circuit Board (PCB) interconnection for the HUAWEI LGA module. By observing the rules, users can ensure the performance of this module in use and reduce costs effectively.
This guide instructs the kernel driver integration development for Huawei Modules based on Embedded Linux & Android operating system. It is intended for the driver developers of the products based on Embedded Linux & Android OS.
This document provides instructions for storage, packing, SMT assembly, and rework of the HUAWEI LGA module, and serves as a guide to secondary assembly of the HUAWEI LGA module. Meanwhile, this document provides PCB design guide for module assembly requirements of producibility and maintainability
The HUAWEI LGA module has two types of packaging:
PCB145-3030M: 145 pin LGA with a dimension of 30 mm × 30 mm
PCB114-3020M: 114 pin LGA with a dimension of 30 mm × 20 mm
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 HUAWEI customers who are integrators and about to implement their applications by using our module.
The HUAWEI LGA module supports the PCM, which can be used for the module to transmit and receive digital audio data. Linear and μ-law codecs are supported. The HUAWEI LGA module uses the PCM interface as part of the audio front end; it easily allows for an external codec to be used instead of the internal codec. As an example, through the PCM you could connect a HUAWEI LGA module to a Bluetooth device.
The 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 ports.
Communications through universal asynchronous receiver/transmitter (UART) serial ports is convenient and reliable. UART serial ports are widely adopted in Huawei modules. This design guide describes the serial port specifications of Huawei modules and provides recommended design schemes for peripheral circuits. When designing UART serial ports for Huawei modules, customers can refer to this document.
Most of Huawei modules provide 8-wire serial ports with flow control. These 8-wire serial ports can also be used as 2-wire or 4-wire serial ports.
Datasheet for Huawei MC509. This document includes an overview of MC509 and it's features. For more detailed technical information, see the Huawei MC509 Hardware Guide.
This document provides information about the major functions, supported services, system architecture, and technical references of HUAWEI MC509 CDMA LGA Module.
This document describes the AT command interface specification that is supported by Huawei terminal product MC509&MC509-a module. This document describes certain AT commands (implemented by terminal devices) of international standards such as TIA/EIA/IS-707-A.3,GSM 07.07, GSM 07.05, and International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) V.250 according to the requirements of terminal devices. In addition, this document describes the proprietary AT command interfaces that are implemented by terminal devices.
This document does not describe the interfaces that have been defined by standards or implemented by the mobile terminal (MT) but are not required by the MC509&MC509-a. The description of AT command interfaces covers only the data packets of interfaces and the methods and processes for the terminal equipment (TE) and the MT to use interfaces, excluding the contents that are not directly related to interfaces. In addition, this document describes only the AT command interfaces falling within the range of Rm interfaces between the TE and MT, excluding the AT command interfaces falling within the range of Um interfaces between the MT and interworking function (IWF).
