The 44th installment of the European Conference on Optical Communication (ECOC) Exhibition recently concluded in Rome, Italy. At the conference, Semtech featured several products for the critical hyper-scale data center and 5G wireless markets. The technologies demonstrated by Semtech from its diverse portfolio of Optical solutions include the ClearEdge® CDR platform for low-cost 25G SFP28 modules that will be an essential component of the 5G infrastructure build out. Additionally, Semtech demonstrated its new line of Tri-Edge CDRs and FiberEdge™ linear Physical Media Dependent (PMD) devices that will help drive current Cloud data center build outs.
China is poised to start the largest wireless infrastructure project in history with the build out of its 5G network. A key component of this effort are the 25G eCRPI front haul links that will be used to connect millions of remote radio heads (RRUs). The GN2146 ClearEdge CDR for eCPRI announced at ECOC 2018 is just one of the mission critical technologies that Semtech has developed to enable 5G. The bi-directional ClearEdge CDR, GN2146, includes an integrated EML/MZM driver and leverages Semtech’s industry leading technology to enable <1.5W max power for SFP28 ER modules with differentiated features like Adaptive CTLE and integrated Bias-T network.
Hyper-scale data centers are at the beginning of a significant technology inflection point with the move from switches with NRZ-based IO to new devices with PAM4 IO. These new switches also double radix size from 6.4T to 12.8T with additional ports putting ever greater pressure on providers to manage power and cost per port.
The GN2558 and GN2559 Tri-Edge CDRs fulfill both of these requirements. The devices feature low power analog receivers that operate at a fraction of the power of traditional DSP-based solutions. Additionally, the devices include both PHY and PMD components thereby saving significant cost over individual components. The GN2559 integrates Semtech’s quad Tri-Edge PAM4 CDRs with Semtech’s market leading linear TIA technology while the GN2558 integrates a high performance linear driver with the quad PAM4 CDRs.
During the conference, Semtech also announced initial production of two devices: its quad ClearEdge CDR with an integrated vertical-cavity surface-emitting laser (VCSEL) laser driver (GN2108S), and its quad ClearEdge CDR with an integrated TIA (GN2109S). The integrated circuits (ICs) offer a very small die size of 3.02 mm by 2.04 mm with 1.36W of combined typical power to enable <2W optical modules.
Semtech is one of the leading global IC suppliers with over a billion Optical ICs shipped worldwide.
