open-in-new Find other Digital signal processors (DSPs)


The TMS320C54V90 is used to implement a full-featured, high-performance modem technology, intended for use in embedded systems and similar applications. This highly integrated solution implements a complete modem using only two chips: the TMS320C54V90 DSP with on-chip RAM and ROM, and the Si3016 line-side DAA.

The modem can connect to a host system serially (RS-232 functionality), or as an 8-bit peripheral to the processor in a host system. The TMS320C54V90 uses a standard Digital Signal Processor (DSP) and proprietary firmware to perform all the modem signal processing, the V.42/V.42bis compression, and AT commands interpretation for modem control functions.

The TMS320C54V90 also uses the latest silicon DAA technology. This technology does not require a transformer and results in lower cost, lower power, and a smaller area for the DAA function.

For serial interface applications, an integrated UART implements the serial interface with no additional hardware.
