  • Patent number: 8321717
    Abstract: A system and method for dynamic frequency adjustment for interoperability of differential clock recovery, including one or more of the following: a frequency generator for receiving a frequency reference clock signal and generating a plurality of frequency signals by operating on the frequency reference clock signal, the plurality of frequencies signals being output from the frequency generator and each having a different frequency; a flexible distributor for receiving the plurality of frequency signals from the frequency generator and selecting ones of said plurality of frequency signals and transmitting said selected ones of said plurality of frequency signals; and a plurality of differential units, each for receiving one of said selected ones of said plurality of frequency signals, each for applying a differential signal to said selected ones of said plurality of frequency signals, and each for adding time stamps to the selected ones of said plurality of frequency signals and outputting respective time sta

  • Patent number: 7929574
    Abstract: A clock distribution mechanism for circuit emulation applications, and related method, including one or more of the following: a plurality of digitally controlled oscillators, each of the plurality of digitally controlled oscillators receiving one or more Ethernet packets and generating a recovered clock from the one or more Ethernet packets; a multiplexer for receiving the recovered clocks generated by the plurality of digitally controlled oscillators, selecting a one of the recovered clocks generated by the plurality of digitally controlled oscillators, and outputting the selected one of the recovered clocks; a normalizer that receives a frequency of the selected one of the recovered clocks and generates a normalized frequency output based on the received frequency of the selected one of the recovered clocks and outputs the normalized frequency output; a clock source selector for receiving a plurality of input clock sources, one of the input clock sources being the normalized frequency output of the normali
