Summary
| Description |
English: The second CDR is designed for a larger tolerance, but is slave to the clock of the first .
Its larger tolerance is obtained widening the range of the phase comparator: 1. the use of the elastic buffer eliminates the LEO tolerance limitation for CDR2, because it samples pulses that have been already regenerated ; 2. the range of the phase comparator (or of the shift register, whichever is smaller) becomes the limit to high frequency jitter tolerance in CDR2 The characteristic cut-off frequency of CDR2 is set lower than CDR1, as much as required for de-jittering the output of CDR1. |
