The SK70725 has all the DSP required for A/D conversion, echo cancellation, data scrambling and adaptive equalization as well as transceiver activation state-machine control. The SK70721 includes D/A and A/D converters, filters, and transmit line drivers. This chipset supports data rates from 272 to 1168 kbps.
