Skyworks Introduces Best-in-Class Jitter Attenuating Clocks to Address High-Speed Communications’ Timing Requirements  New Si536x Product Family Delivers Ultra-High Performance 55 fs RMS for 400/800G networks
Skyworks Solutions, Inc. (Nasdaq: SWKS) today launched its latest portfolio of jitter attenuators for high-speed networking, communications and data center equipment forming the backbone of today’s internet infrastructure. These new products are designed to meet the performance requirements of high-speed networks deployed to carry 5G traffic and support new applications like AI and edge computing. The new Si536x product family complements Skyworks’ current Si539x jitter attenuating clocks to suit the specific timing needs of designers and vendors.
Increasing demand for data bandwidth is driving the need for 400G/600G/800G+ Ethernet links using high-speed 56G/112G/224G PAM-4 SerDes and coherent optical technologies for internet infrastructure and data center environments. The Dell’Oro Group forecasts that these data rates currently comprise half of the total Ethernet data center, with 800G expected to dominate by 2025.1 These high-speed systems require multiple clocks at different frequencies, signaling formats and voltage levels with ultra-low jitter.
To address this need, the Si536x product family provides frequency flexibility and clock tree on-a-chip integration in a compact clock IC solution with up to 18 clock outputs featuring <55 fs RMS jitter, enabling optimal transceiver performance. The increased jitter margin also helps de-risk product development and accelerate time to market for networking equipment vendors.
“Skyworks’ latest product family continues the company’s long-standing history of developing innovative timing solutions, featuring its ultra-low jitter DSPLL® architecture with MultiSynth™ ‘any-frequency’ clock synthesis,” said James Wilson, vice president and general manager of timing products at Skyworks. “These products address the next generation of high-speed communications’ designs, allowing our customers to take advantage of the highest performance, lowest jitter clocks available.”
Skyworks’ Si536x family offers the following features and benefits:
Up to 18 outputs with any combination of frequencies up to 2.75GHz and a wide range of selectable output formats, including LVPECL, LVDS, CML, HCSL and LVCMOS. These output thresholds are also customizable to support chipsets that have non-standard formats.
Seamless input clock management with exceptional input reference clock switching performance, including internal and external hitless switching modes of operation, supporting 35 ps and 75 ps phase transients respectively.
Full suite of clock quality metrics and alarms providing full visibility to clock fault monitoring.
Best-in-class < -90dB power supply rejection, enabling designers to reduce noise filtering components leading to a more cost-efficient solution and simplified bill of materials.
In-circuit reconfigurability enabling output frequency changes on the fly system downtime.

遥遥领先Skyworks品牌推出一流的抖动衰减时钟

Skyworks推出一流的抖动衰减时钟，以满足高速通信的计时要求，新的Si536x石英晶振产品系列为400/800G网络提供超高性能55 fs RMS
Skyworks解决方案公司。(Nasdaq: SWKS)今天推出了最新的抖动衰减器产品组合，用于构成当今互联网基础设施主干的高速网络、通信和数据中心设备。这些新产品旨在满足为承载5G流量而部署的高速网络的性能要求，并支持人工智能和边缘计算等新应用。新的Si536x贴片晶振产品系列补充了Skyworks当前的Si539x抖动衰减时钟可满足设计人员和供应商的特定时序需求。
不断增长的数据带宽需求推动了互联网基础设施和数据中心环境对使用高速56G/112G/224G PAM-4 SerDes和相干光技术的400G/600G/800G+以太网链路的需求。Dell'Oro Group预测，这些数据速率目前占整个以太网数据中心的一半，预计到2025年800G将占主导地位。1这些高速系统要求不同频率、信号格式和电压电平的多个时钟具有超低抖动。
为了满足这一需求，有源晶振Si536x产品系列在紧凑型时钟IC解决方案中提供频率灵活性和时钟树片内集成，最多可提供18路时钟输出，抖动小于55 fs RMS，实现最佳收发器性能。抖动裕量的增加还有助于降低产品开发风险，加快网络设备供应商的上市时间。
“Skyworks的最新产品系列延续了该公司开发创新定时解决方案的悠久历史，其特色是超低抖动DSPLL架构和MultiSynth任意频率’时钟合成，”表示詹姆士·威尔森，副总裁兼计时产品总经理Skyworks。“这些产品针对下一代高速通信设计，允许我们的客户利用最高性能、最低抖动的时钟。"
Skyworks的Si536x系列石英晶体振荡器提供以下功能和优势:
多达18路输出，频率组合最高可达2.75GHz，输出格式可选，包括LVPECL、LVDS、CML、HCSL和LVCMOS。这些输出阈值也可以定制，以支持非标准格式的芯片组。
无缝输入时钟管理，具有出色的输入参考时钟切换性能，包括内部和外部无中断切换工作模式，分别支持35 ps和75 ps相位瞬变。
全套时钟质量指标和警报，提供时钟故障监控的全面可见性。
同类最佳的<-90dB电源抑制，使设计人员能够减少噪声滤波元件，从而实现更具成本效益的解决方案和简化的物料清单。
在线可重构性，使输出频率能够在系统停机时动态变化。
