Discovery Semiconductors adds 25G CDR to Lab Buddy via Gennum chips

Discovery Semiconductors, Inc. says it has integrated Gennum Corp.’s 25G clock data recovery (CDR) technology into its 25-Gbaud Lab Buddy product line for upcoming 100-Gbps datacom and telecom applications.

Discovery Semiconductors, Inc. says it has integrated Gennum Corp.’s 25G clock data recovery (CDR) technology into its 25-Gbaud Lab Buddy product line for upcoming 100-Gbps datacom and telecom applications.

The CDR is frequency agile (operating from 24.8 through 28.3 Gbps), jitter tolerant, and has a user programmable output swing from 200 mV to 1200 mV, according to Discovery Semiconductors. The optical receiver can cover a wavelength range from 800 nm to 1650 nm for singlemode or multimode fiber applications.

Typical applications include active optical cables for Fibre Channel and InfiniBand, as well as testing components and transponders used in telecom and datacom.

Said Abhay Joshi, president and CEO of Discovery Semiconductors, “The marrying of a world-class optical receiver and CDR in Discovery’s Lab Buddy aims to optimize test time by simplifying measurements and improving productivity. This is accomplished through the combination of the O/E and CDR functions by providing both the optical receiver’s linear output, as well as the recovered clock and data outputs simultaneously to your scope or BERA.”

"We developed our 25G CDRs for next-generation 100GbE-LR4, ER4 and OTU4 optical modules," added Ed Frlan, senior system architect in Gennum's Mixed Signal & Optical Products Division. "We are very pleased that Discovery Semiconductors has selected the GN2426 CDR for its 25G Lab Buddy instrumentation."

Discovery will run a live demonstration of the 25G CDR Lab Buddy at next month’s OFC/NFOEC conference in Los Angeles, CA, booth #2501.
