Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the GN2106, a fully integrated quad CDR and EML driver for high performance 100G module applications. The GN2106 is built on Semtech’s industry leading GN2104 quad CDR and adds to Semtech’s full line of quad IC products for 100G modules, including GN1085 quad TIA, GN1185 quad DML driver and GN3485 quad ROSA.

The GN2106 is based on a monolithic design with the CDRs and EML drivers integrated on a single die to help deliver the lower cost structure required to support emerging CFP4 and QSFP28 applications. Leveraging advanced process technology, the single die GN2106 delivers low power and high performance, as well as the high output swings required to drive 25G EML lasers.

“By leveraging our proven CDR technology, we are the first to market with a fully integrated EML driver solution, providing excellent driver performance meeting the jitter and power demands of 100G modules,” said Gary Beauchamp, executive vice president and general manager, Signal Integrity Product Group for Semtech Corporation. “Monolithic integration of the drivers and CDRs provides our customers with the best performance and best overall value, enabling our customers to quickly develop module products to support the fast growing 100G market.”

“Next generation hyperscale datacenters will have large numbers of 100Gbps links at a single site,” said Dale Murray, Principal Analyst, LightCounting Market Research. “The cost of 100Gbps optical modules is critical in these high-volume applications. Monolithic integration of CDR and drivers is a good example of how component vendors are helping overcome the cost challenges.”

The GN2106 will be featured in a live demonstration, showcasing the low power and superior jitter performance, along with Semtech’s new GN3485 100G ROSA at Semtech’s OFC booth from March 24 to March 26.
