The detector uses two moving-average filters of different tap lengths that receive a gain-controlled signal from within the CDR. Output signals from the moving average filters are processed to determine a half-wave time period for each output signal by measuring the number clock cycles occurring between transitions of each output signal. The number of clock cycles of the longest half-wave period is compared to multiple values representing frequency limits of various frequency bands to determine which frequency band to classify jitter the gain-controlled signal. The determined frequency band is used to select from a look-up table a set of gain values for use in the CDR. | 04-16-2015 |
