description
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.
