  • Apparatus and method to measure timing margin in clock and data recovery system utilizing a jitter stressor
    Patent number: 8751880
    Abstract: A method and a system for accurately calculating the timing margin in a clock and data recovery system (CDR) is provided that utilizes a singular path environment of hardware. The method entails adding an amount of jitter within the CDR to change the receiver phase. The amount of jitter is incrementally increased until a threshold level of bit errors occur. Based on the amount of jitter needed to cause the threshold level of bit errors, timing margin can be calculated.
