Semtech Releases 50Gbps Tri-Edge™ CDR Integrated Circuit (IC) Solution


Semtech Corporation (Nasdaq: SMTC), a leading global supplier of high performance analog and mixed-signal semiconductors and advanced algorithms, today announced production of its Tri-Edge™ GN2256. The GN2256 is a bidirectional analog PAM4 CDR with an integrated differential driver offering ultra-low latency, low power and use of low cost 25Gbps bandwidth optics to operate at 50Gbps PAM4.

As 5G deployment continues to increase around the globe, different architectures based on geographic region and carrier preferences are needed to enable expansion in all areas. A key segment for 50Gbps PAM4 deployments will be WDM (Wavelength Division Multiplexing), that send and receive multiple signals using differing wavelengths on a single fiber. The GN2256 has a proprietary driver architecture that is suitable to enable such 50Gbps WDM optical solutions using EML and future silicon photonics MZM optics. The GN2256 combines Semtech’s proprietary analog Tri-Edge technology with enhanced laser driver compensation to enable IEEE and Open Eye MSA compliant optical modules over industrial temperature ranges.
