Overview
The TMS320C54V90GGU, produced by Texas Instruments, is a highly integrated Digital Signal Processor (DSP) designed to implement full-featured, high-performance modem technology. This device is intended for use in embedded systems and similar applications, providing a complete modem solution using only two chips: the TMS320C54V90 DSP and the Si3016 line-side DAA. The modem supports various data modulation standards, including V.90, V.34, V.32bis, and others, and offers advanced features such as V.42/V.42bis compression, AT commands interpretation, and caller ID. It utilizes the latest silicon DAA technology, which eliminates the need for a transformer, resulting in lower cost, lower power consumption, and a smaller footprint.
