A communications controller includes a physical interface and an internal transmit and receive circuit. The physical interface has a port for connection to a communication medium, an input, and an output, and operates to receive a first sequence of data bits from the input and to transmit the first sequence of data bits to the port, and to receive a second sequence of data bits from the port and to conduct said second sequence of data bits to the output. The internal transmit and receive circuit is coupled to the physical interface, and has an internal architecture to conduct a first plurality of symbols at a first rate in a low frequency mode and a second plurality of symbols at a second rate in a low latency mode, wherein the first plurality is greater in number than the second plurality, and the second rate is higher than the first rate. |
