Retimer data communication modules

A data communication device comprising:

• a host receive section for receiving incoming host data from a host device, the host receive section including a plurality of host receive lanes;
• a host transmit section for transmitting outgoing host data to the host device, the host transmit section including a plurality of host transmit lanes and a host cross point section;
• a line receive section for receiving incoming line data from a line device, the line receive section including a plurality of line receive lanes;
• a line transmit section for transmitting outing line data to the line device, the line transmit section including a plurality of line transmit lanes and a line cross point section;
• and
• a link monitor section coupled to the host transmit section and the line receive section;
• wherein the line receive section comprises:
• an analog front end (AFE) configured to process line data in a pulse-amplitude modulation (PAM) format, the AFE comprising an equalizer;
• and
• a digital-signal processing (DSP) module configured to process the line data, the DSP module comprising a feedforward equalization module and a slicer.

A high-speed communication system comprising:

• a plurality of communication lanes;
• a transceiver being configured to process and transmit host data received from the plurality of communication lanes, the transceiver comprises:
• a host receive section for receiving incoming the host data;
• a host transmit section for transmitting outgoing host data to a host device, the host transmit section including a plurality of host transmit lanes and a host cross point section;
• a line receive section for receiving incoming line data from a line device, the line receive section including a plurality of line receive lanes;
• a line transmit section for transmitting outing line data to the line device;
• and
• a link monitor section coupled to the host transmit section and the line receive section;
• a management interface module coupled to the link monitor section;
• wherein the line receive section comprises:
• an analog front end (AFE) configured to process line data in a pulse-amplitude modulation (PAM) format, the AFE comprising an equalizer and a variable gain amplifier;
• a phase-lock loop module for generating a clock signal;
• and
• a digital-signal processing (DSP) module configured to process the line data.
