Clock and Timing by Skyworks

A comprehensive portfolio of oscillators, clock buffers, clock generators, PCI Express (PCIe) clocks, jitter attenuators and SyncE/IEEE 1588 network synchronizers with PTP software.

Clock and Timing

Skyworks offers a broad portfolio of timing products that enable hardware designers to simplify clock generation, clock distribution, jitter attenuation and network synchronization. These products combine best-in-class jitter performance and frequency flexibility, enabling customers to easily architect optimized clock tree solutions. Custom samples are available in 1-2 weeks, easing design and reducing time-to-market.

Clock Generator

Crystal Oscillators

Skyworks offers the industry’s lowest jitter, most frequency flexible, most highly integrated clock generators. Leveraging Skyworks’ proven MultiSynth technology, a single clock generator can replace an entire clock tree of multiple oscillators, buffers, clock generators, and muxes, simplifying design and accelerating time to market. Skyworks’ comprehensive clock generator portfolio offers optimized solutions for communications, data center, industrial and consumer applications.

Jitter Attenuating Clocks

Jitter Attenuating Clocks

Skyworks offers the industry’s lowest jitter, most frequency flexible and integrated jitter attenuating clock generators for Wireless, Wireline , and Data Center equipment. Leveraging Skyworks’ proven DSPLL® and MultiSynth technology, a single jitter attenuating clock can synchronize to a wide range of different clocks, filter jitter, and provide any combination of output frequencies, including JESDB2024B/C support. Skyworks offers an extensive range of jitter attenuating clocks to solve the most complex timing challenges in 4G/5G Radio, 100G+ packet optical transport and Ethernet designs.

Crystal Oscillators XO & VCXO

Crystal Oscillators

Skyworks offers a comprehensive portfolio of high performance, low jitter XOs and VCXOs. Skyworks’ new Si54x and Si56x Ultra SeriesTM family of high performance XOs and VCXOs delivers ultra-low jitter and frequency flexibility.

crystal oscillators example

Skyworks’ new Si56x Ultra Series™ family of high performance VCXOs deliver exceptional jitter performance and 5x tighter control voltage linearity than competing solutions, maximizing design margin while simplifying development. All devices are highly customizable, with samples of any XO and VCXO available with 1-2 week lead times.

NetSyncTM Network Synchronizers with AccuTimeTM IEEE 1588 Software

NetSyncTM Network Synchronizers with AccuTimeTM IEEE 1588 Software

Skyworks offers the industry’s most highly integrated clocking solutions for Wireless and Wireline equipment, including 5G radio access networks replacing three devices with a single NetSyncTM network synchronizer IC simplifying the overall BOM. Leveraging Skyworks’ proven fifth-generation DSPLL and MultiSynth technology, a single NetSyncTM clock supports Synchronous Ethernet (SyncE)-compliant wander filtering, 1PPS/PP2S inputs, and software adjustment of output frequency and phase for IEEE 1588 applications, with support for CPRI/eCPRI JESD204B/C. These devices offer ultra-low jitter, ultra-low phase noise output clocks, eliminating the need for a follow-on jitter attenuator device. With up to 3 DSPLLs and flexible MultiSynth placement this unique architecture can reduce complexity and size while achieving low power consumption.

NetSyncTM clocks can be combined with Skyworks’ AccuTimeTM software to provide a fully standards compliant IEEE 1588 Precision Time Protocol (PTP) solution operating in full timing support (FTS), partial timing support (PTS), assisted partial timing support (APTS), and PTP-unaware networks. Alternatively, NetSyncTM clocks can be used with just the servo portion of AccuTime alongside an existing PTP stack implementation to achieve superior performance without increased software effort, or just the NetSyncTM device can be used with third-party PTP software.
