Description:
The Discovery Semiconductors Inc. reference-free 1:1 Clock & Data Recovery (CDR) unit, included in the Lab Buddy, conveniently interfaces with the Bit Error Rate (BER) test equipment and provides a Receive, Reshape, & Retime (3R) solution, which is especially important for transmission experiments.
This state-of-the-art instrument contains several features to enhance its flexibility. The CDR has been configured for variable data rate operation ranging from 24.8 Gb/s to 28.3 Gb/s. The CDR can be operated at sub-rates of /2, /4, /8 & /16 over the full rate operating range listed above. Additionally, the CDR can be utilized as a Clock Multiplying Unit (CMU) where a sub-rate clock can be multiplied up to 24.8 GHz to 28.3 GHz. Additional features include adjustable input equalization, adjustable clock & data output amplitude, selectable recovered clock output rate ranging from full rate to /128 in binary steps. The CDR provides Loss of Signal (LOS) & Loss of Lock (LOL) indicators.
