This paper describes a measurement of high-frequency jitter contributed by a clock-and-data recovery circuit. The contributed jitter is expressed with deterministic and random jitter terms and is given for a specific bit sequence. The measurement is illustrated on two multichannel CMOS serializer/deserializer chips applicable to 10-G Ethernet, 10-G Fibre Channel, and InfiniBand at per-channel rates of 2.5 and 3.125 GBaud.
