Overview
The TMS320C54V90BPGE is a highly integrated Digital Signal Processor (DSP) from Texas Instruments, designed to implement full-featured, high-performance modem technology. This DSP is intended for use in embedded systems and similar applications. It forms a complete modem solution using only two chips: the TMS320C54V90 DSP and the Si3016 line-side DAA. The modem can connect to a host system either serially (RS-232 functionality) or as an 8-bit peripheral to the processor in a host system. It utilizes standard DSP architecture and proprietary firmware to handle modem signal processing, V.42/V.42bis compression, and AT commands interpretation for modem control functions.
