Semtech Announces Production of Tri-Edge™ PAM4 CDR Chipset to Support 100G Data Center Fiber Links

The new CDR chipset is based on the industry-leading 200G and 400G GN2558 and GN2559 Tri-Edge chipsets.

Extensions can help achieve lower power consumption, lower latency and lower costs for multimode fiber links up to 100 meters

January 5, 2022 - Semtech Corporation (NASDAQ: SMTC), a global leading supplier of high-performance analog and mixed-signal semiconductors and advanced algorithms, announced that its latest Tri-Edge™ CDR chipsets, GN2538 and GN2539, have been fully mass-produced to help the next generation of data centers achieve multimode fiber interconnection. The GN2538 is a dual-channel 50G PAM4 CDR with an integrated VCSEL driver; while the GN2539 is a dual-channel 50G PAM4 CDR with an integrated linear transimpedance amplifier (TIA). As the latest members of the mature Tri-Edge CDR platform, the low power consumption and easy deployment advantages of the GN2538 and GN2539 chipsets can help major data centers upgrade their internal interconnection levels and improve overall performance.

As more industries and consumers turn to online activities such as streaming, social media, e-commerce and telemedicine, the demand for information is growing, which has accelerated the change in data center requirements. The COVID-19 pandemic has further accelerated the trend of data usage, and as more companies conduct business online, the availability of data and computing has received unprecedented attention. Semtech's Tri-Edge SR CDR solution achieves low power consumption and low latency performance, enabling seamless data transmission as data rates continue to grow, while providing lower power consumption, helping to reduce the impact of data centers on the environment.

“Our customers have thoroughly tested these solutions and confirmed their interoperability with 100G ports of commercial Ethernet switches used in major data centers,” said Julius Yam, Data Center Product Marketing Manager for Semtech’s Signal Integration Products Group. “The integration provided by the analog PAM4 GN2538 and GN2539 chipsets reduces costs while delivering the ideal low power and low latency performance required for high performance computing (HPC), artificial intelligence (AI) and cloud data center networks. The chipsets are also fully compliant with the Open Eye MSA standard for 50G per lane multimode fiber.”

The GN2538 integrated laser driver includes proprietary VCSEL compensation to enable a wide range of VCSEL selection, fully adaptive input equalization, and easy startup to simplify system setup. The GN2539 integrated linear TIA provides excellent receiver performance and reliable adaptability, and includes configurable output de-emphasis for a robust and compatible electrical interface.
