20070253515 - Clock regeneration circuit technical field: Clock synchronization resistance is improved against selectivity fading without degrading the stability of clock phase synchronization control. Clock phase detector 7, which forms part of a clock reproduction PLL, is preceded by orthogonal component equalizer 6 for removing only orthogonal component interference wave not affecting the clock regeneration, thereby assuring... Agent: Mcginn Intellectual Property Law Group, PLLC

20070253516 - Jitter correction method and circuit: In a jitter correction method and circuit, combination data combined by adding, to referenced data, an end bit of data 1 clock prior to and a head bit of data 1 clock subsequent to the referenced data is sequentially generated. Each bit of the combination data is sequentially referred. When... Agent: Bingham Mccutchen LLP

20070253517 - Method and apparatus for integral state initialization and quality of lock monitoring in a clock and data recovery system: Methods and apparatus are provided for improving the performance of second order CDR systems. The integral state of the CDR system is initialized to a value that is based on an expected frequency profile that may be known a priori for certain applications. One or more quality of lock (QOL)...
