Overview

The SigSD4-SODIMM audio module provide small-form factor 4-channel 16-bit sigma-delta analog I/O solution compatible with the SigC54xx and SigC67xx PC104 boards. By providing dedicated analog I/O in the SODIMM form-factor, a completely modular approach can be utilized for the DSP component in telecom infrastructure applications. Analog I/O data can be routed directly to multiple DSP devices via high-speed TDM serial bitstream, and thus increase system performance and efficiency. The modular approach also creates flexibility in configuring the number of analog I/O channels vs. DSP processors, and allowing customer upgrades to more voice or audio channels. Below are some features of the SigSD4-SODIMM audio module:

Module Descriptions

The SigSD4 module contain (2) CS4218 16-bit sigma-delta codec devices. Each codec device is a monolithic stereo (2-channel) A/D and D/A converter, with built-in anti-alias input filters and reconstruction output filters. All channels are sampled simultaneously.

The SigSD4 audio module provide a selection of sampling rates (including 8 kHz speech rate), input gain, and output attenuation under software control. See Specifications section below for details.

When used with SigC54xx and SigC67xx board, the SigSD4 audio module is fully supported by the following off-the-shelf software development packages:

The DirectDSP sofware includes support for popular host programming environments, including MATLAB®, C/C++ (MSVC and Borland), Visual Basic, and LabVIEW. See Software Support below for more information.
