领先全球思佳讯差分晶体振荡器适用于人工智能

领先全球思佳讯差分晶体振荡器适用于人工智能，加州欧文。--Skyworks解决方案公司。(纳斯达克代码:SWKS)，今天宣布其Si5332系列高性能时钟发生器的演进，支持向PCI Express第6代(PCIe 6.0)的行业过渡。根据PCI-SIG的说法，包括人工智能、机器学习和边缘计算在内的新应用正在推动数据中心计算、交换和存储平台对更高性能和更高带宽互连的需求1。来自的Si5332产品系列Skyworks支持PCIe 6.0，同时保持向后兼容旧的PCIe标准。

“PCIe 6.0是数据中心的未来，而且Skyworks帮助IC供应商在过渡到最新的PCIe标准时充满信心地进行设计。”詹姆士·威尔森，副总裁兼计时产品总经理Skyworks。“凭借我们数十年来为高速串行互连应用提供高性能、低抖动石英晶体振荡器解决方案的专业经验，我们已经证明我们的Si5332系列能够为最新的PCIe 6.0应用提供参考时序。”

PCIe 6.0将数据速率提高到64GT/s，带宽高达256Gbps，有效地将PCIe 5.0的性能提高了一倍。这一对PCIe标准的最新升级确保了数据中心应用中使用的高速互连不会成为瓶颈，并补充了行业向400G和800G以太网的过渡。与使用NRZ信令的前几代PCIe标准不同，PCIe 6.0使用PAM4调制将两个比特组合成具有四个幅度级别的单个符号。这种方法将传输速度提高了一倍，但通过用三个较小的数据眼代替一个较大的数据眼，降低了眼图的质量。使用低抖动PCIe参考时钟可以最大化PAM4数据眼图张开度，并最小化误码率，这对于更快的传输速度是必要的。

Si5332差分晶体振荡器的任意频率时钟合成、低抖动操作和对PCIe 6.0的支持使其非常适合用单个IC取代固定功能振荡器、时钟和缓冲器。设备功能Skyworks专有多合成铥小数分频器技术，提供任意频率合成和出色的抖动性能。Si5332提供6路、8路和12路输出选项，支持集成格式/电平转换、LVPECL、LVDS、HCSL和LVCMOS以及1.8-3.3V VDDO工作电压。结合对PCIe 6.0的支持，Si5332非常适合用作数据中心的片上时钟树，用高度集成的高性能解决方案取代多个时序元件。器件样片现已上市。

Skyworks将在消费电子展10850号展位展出，地点在拉斯维加斯从2023年1月5日至8日.

IRVINE, Calif.--(BUSINESS WIRE)--Dec. 15, 2022-- Skyworks Solutions, Inc. (Nasdaq: SWKS), today announced the evolution of its Si5332 family of high-performance clock generators, supporting the industry transition to PCI Express Generation 6 (PCIe 6.0). According to PCI-SIG, new applications including artificial intelligence, machine learning and edge computing are driving the need for higher performance and increased bandwidth interconnects for compute, switching and storage platforms in data centers1. The Si5332 product family from Skyworks supports PCIe 6.0 while maintaining backwards compatibility with older PCIe standards.

“PCIe 6.0 is the future of the data center, and Skyworks is helping IC suppliers design with confidence when they make the transition to the latest PCIe standard,” said James Wilson, vice president and general manager of timing products at Skyworks. “Drawing from our decades of expertise in providing high-performance, low-jitter timing solutions for high-speed serial interconnect applications, we have qualified our Si5332 family to provide reference timing for the newest PCIe 6.0 applications.”

PCIe 6.0 increases data rates to 64GT/s and enables bandwidths as high as 256Gbps, effectively doubling the performance of PCIe 5.0. This latest upgrade to the PCIe standard ensures the high-speed interconnects used in data center applications do not become a bottleneck and complements the industry’s transition to 400G and 800G Ethernet. Unlike prior generations of the PCIe standard that used NRZ signalling, PCIe 6.0 uses PAM4 modulation to combine two bits into a single symbol with four amplitude levels. This approach doubles the transfer speed but degrades the eye diagram by replacing a single, large data eye with three smaller data eyes. Using a low jitter PCIe reference clock maximizes the PAM4 data eye opening and minimizes bit-error rate, which is necessary for faster transfer speeds.

The Si5332’s any-frequency clock synthesis, low jitter operation and support for PCIe 6.0 makes it ideally suited to replace fixed function oscillators, clocks and buffers with a single IC. The device features Skyworks proprietary MultiSynthTM fractional divider technology, which provides any-frequency synthesis and excellent jitter performance. The Si5332 is available in 6, 8 and 12-output options, with support for integrated format/level translation, LVPECL, LVDS, HCSL and LVCMOS, and 1.8-3.3V VDDO operation. When combined with support for PCIe 6.0, the Si5332 is well suited to operate as a data center clock-tree-on-a-chip, replacing multiple timing components with a highly integrated, high-performance solution. Device samples are available now.

In addition to this Si5332 product announcement, Skyworks is pleased to announce PCIe 6.0 support in its PCIe Jitter Tool. Long regarded as the industry standard for measuring PCIe clocks and evaluating compliance to PCIe jitter specs, the PCIe Jitter Tool now allows users to take accurate jitter measurements on PCIe 6.0 reference clocks.

Skyworks will be exhibiting at the Consumer Electronics Show Booth No. 10850, taking place in Las Vegas from Jan. 5-8, 2023.
