LOW VOLTAGE MODEM PLATFORM BASED ON TMS320LC56

This application report presents a modem reference design based on the TMS320LC56 DSP. The advanced peripherals of this device provide the features necessary for integration into complex systems optimizing access times and minimizing external logic. A software analysis at the beginning shows that the computing power of the LC56 is sufficient to support even the highest standards of voice and data transmission. The 3.3V technology of this DSP also makes it possible to integrate this solution in systems such as portable computers where low power consumption is the prime consideration. The combination of 5V with 3.3V devices is also discussed in this report. Onboard line interface, UART, large memory and expansion connectors bring a high degree of flexibility to this design, building a generic evaluation platform.
