Patent number: 7738498Abstract: A system including a memory (storing a set of data records), a digital phase-locked loop (PLL) and digital circuitry. Each of the data records is allocated to one packet stream in a set of packet streams. The digital circuitry is configured to: invoke a read operation from the memory in response to a received stream indicator and received channel indicator corresponding to a current timestamp-bearing packet; generate an output timestamp for the current packet equal to an expected timestamp provided by the memory as part of the read operation; and generate error data based on argument data including a received input timestamp, a received slot delay value, a previous source frequency estimate and an expected timestamp provided as part of the read operation. The digital PLL is configured to compute an updated source frequency estimate based on information including the error data and the previous source frequency estimate.Type: GrantFiled: August 9, 2005Date of Patent: June 15, 2010Assignee: Oracle America, Inc.Inventors: James J. Yu, Andrew C. Yang

Patent number: 7333468Abstract: A packet stream multiplexer may include one or more control loops (e.g., digital phase locked loops) for tracking the source clock frequency associated with a packet stream. A first control loop may slowly drive an error between a received timestamp and an estimated timestamp to zero. A second control loop may more quickly drive a first derivative of the error to zero. The second control loop may include a set of digital filters ordered according to tracking speed. The output of the slowest filter is initially selected for updating the source clock frequency estimate. As time progresses, the faster filters are selected in succession. The estimated source clock frequency is used to restamp packets of the packet stream as they are sent out onto an output channel.Type: GrantFiled: May 16, 2005Date of Patent: February 19, 2008Assignee: Sun Microsystems, Inc.Inventors: Sebastian Turullols, Aly E.

Patent number: 4857973Abstract: The invention comprises a Schottky barrier type infrared photodetector which is monolithically integrated on a silicon waveguide. A Schottky barrier contact is positioned directly on a silicon waveguide to absorb grazing incidence optical signals passing through the waveguide. The Schottky contact is operated in the avalanche or reverse bias mode to generate a useable electrical signal.Type: GrantFiled: May 14, 1987Date of Patent: August 15, 1989Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Andrew C.

Patent number: 4714314Abstract: A mode dependent, optical time delay system for electrical signals having a highly multi-mode optical fiber having a step index profile in optical alignment with an optical source which is capable of converting an incoming electrical signal into an optical signal. By incorporating within the system a number of different components to alter or control the mode angles of the incoming optical signal, the resultant optical output signal is time delayed as it propagates through the optical fiber. This optical output signal is thereafter converted into an electrical output signal which is also time delayed in direct relation to the mode angle of the optical signal propagating through the optical fiber.Type: GrantFiled: February 6, 1985Date of Patent: December 22, 1987Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Andrew C. Yang, Richard Payne, Richard A. Soref
