  • US Patent:
    7545899, Jun 9, 2009
  • Filed:
    Mar 31, 2004
  • Appl. No.:
    10/813235
  • Inventors:
    Abbas Amirichimeh - Irvine CA, US
    Howard Baumer - Laguna Hills CA, US
    John Louie - Huntington Beach CA, US
    Vasudevan Parthasarathy - Irvine CA, US

  • Assignee:
    Broadcom Corporation - Irvine CA
  • International Classification:
    H04L 7/00
    H04L 25/40
  • US Classification:
    375358, 375371
  • Abstract:
    Systems and methods for synchronizing a receive clock signal phase with a transmit clock signal phase are presented. A system includes a receiving channel and a transmitting channel, wherein the transmitting channel synchronizes a transmit clock signal phase with a receive clock signal phase based on receive clock signal phase data. A method includes storing a previous receive clock signal phase of a receiving channel and identifying a current receive clock signal phase of the receiving channel. The method further includes determining a phase difference between the previous receive clock signal phase and the current receive clock signal phase, and identifying a direction of the phase difference. The method further includes adjusting a previous transmit clock signal phase of the transmitting channel to a current transmit clock signal phase of the transmitting channel based on the phase difference and direction.

  • US Classification:
    375219, 375220, 375356
  • Abstract:
    A transceiver system is disclosed that includes a plurality of transceiver chips. Each transceiver chip includes one or more SERDES cores. Each SERDES core includes one or more SERDES lanes. Each SERDES lane includes a receive channel and a transmit channel. The transmit channel of each SERDES lane is phase-locked with a corresponding receive channel. The transceiver system has the capability of phase-locking a transmit clock signal phase of a transmitting component with a receive clock signal phase of a receiving component that is a part of a different SERDES lane, a different SERDES core, a different substrate, or even a different board. Each SERDES core receives and transmits data to and from external components connected to the SERDES core, such as hard disk drives. A method of transferring data from a first external component coupled to a receive channel to a second external component coupled to a transmit channel is also disclosed.

  • International Classification:
    H04L 13/10
  • US Classification:
    370304
  • Abstract:
    A cross link multiplexer bus comprising a plurality of cross link multiplexers and a plurality of interconnects. The plurality of cross link multiplexers has a destination port configured to receive a signal and an origin port configured to produce the signal. The plurality of interconnects has a set of interconnects coupled between a pair of adjacent cross link multiplexers. Preferably, the destination port is in a first cross link multiplexer, the origin port is in a second cross link multiplexer, and the first cross link multiplexer is configured to convey the signal toward the second cross link multiplexer in more than one direction. In an embodiment, the signal is capable of being represented as a series of characters, and a character is capable of being represented as a number of bits. Preferably, the plurality of cross link multiplexers includes a delay buffer to delay conveyance of a first bit so that it remains substantially synchronized with a second bit. Preferably, the set of interconnects includes a first interconnect to convey the first bit and a second interconnect to convey the second bit.
