GX4002
GX4002 是一款低功耗、高速 2 x 2 交叉点开关,具有强大的信号调理电路,用于通过背板驱动和接收高速信号。在所有通道均可运行的情况下,此器件的功耗低至 600mW(典型值)。可以关闭芯片的未使用部分,以进一步降低功耗。
GX4002 的信号调理功能包括每个输入的时钟和数据恢复 (CDR)、可编程均衡和每个输出的可编程去加重。输入均衡器通过在使用长 PCB 迹线的应用中打开输入数据眼图来消除 ISI 抖动(通常由 PCB 迹线损耗引起)。集成的 CDR“重置”抖动预算,有效消除传输过程中可能发生的信号失真。
输出预加重功能可增强输出信号的高频成分,从而使数据眼图在通过 PCB 迹线和连接器的长互连后保持打开状态。
GX4002 配置有集成模数转换器,可通过串行接口,提供有关电源电压和芯片温度的数字诊断信息。
GX4002 器件采用小外形 5mm × 5mm 32 引脚高频 QFN 封装,带有裸焊盘。
GX4002 为无铅器件,包封复合物中不含有卤系阻燃剂。此部件和所有同类子部件均符合 RoHS 要求。

From smartphones and laptops, to ATMs and online shopping, data is constantly in flight. As consumer technology and industry innovations advance, global data creation is projected to grow to 175 zettabytes (ZB) by 2025. Nearly 53ZB of that data will be consumed in real time—the data equivalent of streaming 583 billion 4K videos at once—which will strain current network infrastructure.
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years ago when the Consortium for On-Board Optics (COBO), of which Semtech is an associate member, was launched, has been replaced by a realization that only slow migration from traditional pluggable modules will serve the data center, whether within a single line card or server blade, or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.
