  • Publication number: 20040208180
    Abstract: A system and method are provided to support auto-negotiation between at least two communication devices among standards having different data rates. Base page configuration information and next page configuration information are exchanged between the at least two communication devices at a first data rate over a single serial channel. Ability matching is performed by the at least two communication devices using the base page and next page configuration information. A communication link is established between the at least two communication devices over the single serial channel at a negotiated first data rate, or over multiple parallel serial channels at a negotiated second effective data rate, depending on at least a result of the ability matching.

  • Patent number: 6292912
    Abstract: A disk drive has a normal mode of operation and a built-in self-test (BIST) mode of operation for producing a sequence of channel metrics {&Ggr;n}. The disk drive includes a recording surface having a plurality of bit cells and a transducer for reading the plurality of bit cells to produce a noise-corrupted read signal. The disk drive further includes means responsive to the noise-corrupted read signal for generating a sequence of observed samples {yn}, the sequence of observed samples {yn} forming a sequence of observed-sample subsequences {Yn}. An expected sample generator operates during the BIST mode of operation to provide a sequence of expected samples {wn}, the sequence of expected samples forming a sequence of expected-sample subsequences {Wn}. A channel metrics &Ggr;n computation system computes a sequence of channel metrics {&Ggr;n}.

  • Patent number: 5861766
    Abstract: A frequency synthesizer has multiple modes of operation including a relatively short-duration frequency seek mode and a relatively long-duration normal mode. The synthesizer responds to a reference frequency signal and produces a periodic signal at a frequency that is a rational number times the frequency of the reference frequency signal. The synthesizer comprises a VCO, a feedforward state machine, a feedback state machine, a phase comparator, controllable gain circuitry between the phase comparator and the VCO, and logic circuitry that coordinates the operation of the feedforward and feedback state machines during the seek mode.
