  • Distributed delay-locked-based clock and data recovery systems
    Patent number: 7456670
    Abstract: A clock and data recovery system using a distributed variable delay line is provided. The clock and data recovery system can use a delay-locked loop methodology to align a local clock with an incoming data stream. The variable delay line can include a transmission line coupled with a plurality of variable capacitors responsive to a control voltage. The variable delay line can also have a ladder configuration of multiple LC subcircuits each having a variable impedance responsive to a control voltage.
    Type: Grant
    Filed: May 11, 2006
    Date of Patent: November 25, 2008
    Assignee: The Regents of the University of California
