Multi-Rate CDR with DML Driver 32-Pin QFN

The GN242 are new clock and data recovery (CDR) retimers designed to support the implementation of 100Gb Ethernet and OTU4 optical modules. They are designed to handle 25Gb/s data streams within next-generation 100Gb/s pluggable fiber-optic modules, line cards and direct-attach copper cables.

• Enable OIF CEI-28G-VSR retimed interfaces by compensating for losses in the data transmission and resetting the jitter budget
• Optimized for best jitter performance at lowest power
• Designed specifically for the next-generation 100GbE CFP2 module form-factor
• Allow for the serialize and deserializer to be positioned outside of the CFP2 module enabling a simpler, lower power and lower cost solution
• Enable higher module density and faster serial bit rates
• GN242 provides excellent output jitter performance for optimal interfacing to laser drivers, RF amplifiers or Mach-Zehnder modulator drivers
• In the receive chain, the GN242 removes jitter from the recovered optical signal, providing ample margin for line card receivers to recover the high-speed data stream from the module
