Semtech’s Tri-Edge™ GN2255 is the industry’s first analog IC solution enabling ultra-low latency, less than 1.5W module power, and performance for up to 10km reach for 50Gbps PAM4 SFP56 optical modules. Based on the proven Tri-Edge CDR platform qualified in data center applications, the new solution delivers the cost effectiveness, small footprint, low power, ultra-low latency, and performance demanded by 5G front haul applications. The new Tri-Edge GN2255 enables 50Gbps PAM4 links that will double the bandwidth of currently deployed 25Gbps NRZ front haul links. Semtech’s introduction of the Tri-Edge 5G wireless IC will help support new 5G applications, including edge computing, enhanced mobile broadband and device streaming, and fixed wireless access (i.e., home Internet).

今年早些时候,评估工程 (EE) 与 Semtech 信号完整性产品事业部高级营销经理 Raza Khan 进行了交谈,讨论了行业趋势和新 Tri-Edge 5G 无线产品。
立即阅读在 2018 年进行了大量演示和 alpha 模块测试之后,双密度版本的四通道小型可插拔 (QFSP) 多源协议 (MSA) 模块标准有望成为新线卡的规则。QSFP-DD 热潮的隐含意义不是模块本身的物理特性,而是转向先进信令方法的趋势。十年前,QSFP28 的问世预示着使用 NRZ 信令的 25Gbps 电通道即将占据主导地位。如今,QSFP-DD 及其更庞大的表亲 —— 八进制 SFP 或 OSFP ,都使用 PAM4 信令。其用得最多的是 50Gbps 通道。但 QSFP-DD 足够灵活,可以在各种实施中使用八通道接口:25G x 8 用于 200Gbit 以太网,50G x 8 用于 400Gbit 以太网,可能还有一些早期的 100G x 8 用于预标准 800Gbit 以太网。
立即阅读Slow but steady advances were made in 2018 in on-board optical links for chip-to-chip and chip-to-module interfaces. The integrated-optics revolution, anticipated three years ago when the Consortium for On-Board Optics (COBO), of which Semtech is an associate member, was launched, has been replaced by a realization that only slow migration from traditional pluggable modules will serve the data center, whether within a single line card or server blade, or between cards and racks. Even as recent as a year ago, COBO members began rethinking and changing their tune to stress coexistence of pluggable MSA modules and the embedded on-board modules chosen by COBO as a de facto standard.
