Abstract
Some embodiments of the invention provide a biased tracking loop that may include encoded information. Embodiments may comprise a training pattern, utilized in a non-interfering way that allows for clock recovery, embedded information transmission and/or header alignment. Therefore, embodiments may comprise a tracking loop training pattern that comprises data.
Claims23
A method for a biased clock recovery tracking loop comprising:
- receiving header information in a training sequence;
- receiving control information in the training sequence;
- receiving a clock training pattern in the training sequence;
- and
- decoding data encoded in the control information while deriving a clock from the training sequence.
An apparatus comprising a machine-readable medium containing instructions that, when executed, cause a machine to:
- receive header information in a training sequence;
- receive control information in the training sequence;
- receive a clock training pattern in the training sequence, the clock training pattern to be used clock recovery;
- and
- decode data encoded in the control information and derive a from the training sequence.
An apparatus comprising:
- a link to receive a training sequence containing encoded information;
- and
- a circuit coupled with the link, the circuit to recover clocking information from the training sequence with a biased clock recovery tracking loop.
A host controller comprising:
- a link to send a training sequence containing encoded information;
- and
- a circuit coupled with the link, the circuit to provide clocking information in a training sequence.
A system comprising:
- a general purpose processor;
- and
- a host controller coupled with the general purpose processor, the host controller comprising:
- a link to send a training sequence containing encoded information;
- and
- a circuit coupled with the link, the circuit to provide clocking information in a training sequence.
