  • Clock data recovery circuit
    Patent number: 9413518
    Abstract: Systems and methods for stabilizing clock data recovery (CDR) by filtering the abrupt phase shift associated with data pattern transition in the input signal. The CDR circuit includes a data pattern detector coupled to a data pattern filter. The data pattern detector is capable of detecting the data patterns of the input signal. Accordingly, the data pattern filter can selectively generate a filter indication indicating to freeze or suppress the CDR phase caused by data pattern transition. The filter indication can be incorporated to a phase error signal, a gain function, and/or the control voltage driving the VCO.
