US 10,484,046 B1 · Systems and methods for a twisted pair transceiver with correlation detection

Abstract

The systems and methods for a twisted pair transceiver with correlation detection includes a transceiver system operating on a cable. The transceiver system includes a receiver to obtain one or more data samples related to one or more encoded data symbols. The transceiver system further includes a first correlation filter to generate a first correlation output based on the one or more data samples, and a second correlation filter to generate a second correlation output based on the one or more data samples. The transceiver system further includes a detector. The detector compares the first correlation output with the second correlation output, generates an output data bit based on a comparison result, and sends the output data bit for data decoding.

Dependent claims

A method for transmitting data on an Ethernet link between a first device compatible with a first Ethernet transmission protocol and a second device compatible with a second Ethernet transmission protocol, the method comprising:

selecting a third baud rate to be a common factor of both a first baud rate specified in the first Ethernet transmission protocol and a second baud rate specified in the second Ethernet transmission protocol;
receiving, at the first device and from the second device, one or more encoded data symbols at the third baud rate;
determining a clock division factor based on the first baud rate and the third baud rate;
sampling, at the first device, the one or more encoded data symbols using a divided clock signal based on the clock division factor;
and
generating, from the sampling, a number of samples representing at least one data symbol, wherein the number equals a result of the first baud rate divided by the common factor.
