BUILT-IN TEST SCHEME FOR A JITTER TOLERANCE TEST OF A CLOCK AND DATA RECOVERY UNIT

摘要

A jitter test system for a clock and data recovery unit (CRU) is comprised of a data generating apparatus, apparatus for clocking the data generating apparatus with a jittered clock, apparatus for applying a stream of data generated by the data generating apparatus that has been jittered by the jittered clock to an input of the CRU, and apparatus for detecting a bit error rate of a data signal output from the CRU.
