Patent Number Title Of Patent Date Issued
8014480 Zero-delay serial communications circuitry for serial interconnects September 6, 2011
Circuitry and methods for supporting serial communications over serial interconnects between circuit modules are provided. A data recovery circuit receives incoming serial data from the serial interconnect path with zero delay. The data recovery circuit includes a data sampler that s
7843275 Frequency synthesizer circuitry employing delay line November 30, 2010
Frequency synthesizer circuitry employs a delay line. A reference clock signal propagates through successive stages of the delay line, and the currents drawn by output buffers of all of the stages are added at a common node. The common node current is converted to a voltage, which is
7633322 Digital loop circuit for programmable logic device December 15, 2009
A digital loop circuit--i.e., a phase-locked loop ("PLL") or delay-locked loop ("DLL")--having a simplified digital loop filter, is particularly well-suited for a programmable logic device ("PLD"). The loop filter may be a memory (e.g., a shift register) which counts the early/late or
