Insights

Timing IC Product Strategist

New BAW-based programmable clocks aim to cut BOM and deliver ultra-low jitter for high-speed wireline, wireless and data-center links.

These devices combine Skyworks' BAW resonator with DSPLL and MultiSynth architectures to provide very low jitter and phase noise across broad frequency ranges, removing external quartz/XO/VCXO references and enabling multi-channel outputs from a single chip. The key technical claims—17 femtoseconds jitter for 224G PAM4 SerDes and CPRI phase noise of -142 dBc/Hz at 100 kHz offset—address tight timing budgets in 800G–1.6T optical links, DCI, and 5G/6G radio synchronization.

Dependencies and risks are clear and product-specific: system-level benefit depends on actual silicon performance in target designs, interoperability with existing transceivers and PHYs, and thermal/power behavior in deployed environments. The products support a 60% lower typical power claim versus "traditional solutions" and a -40 to +95°C range, which matter for base stations and non-temperature-controlled equipment but require validation in real designs.

Concrete items to watch include customer evaluation outcomes using the SKY63103-EVB and SKY69101-EVB kits, time-to-design-win in optical and radio OEMs, and volume production uptake following the announced availability on Nov. 06, 2025. Expect meaningful signals within the next 3–12 months as samples move into system testing and design cycles.

Breakthrough Timing Solutions Deliver Ultra-Low Jitter for 224G PAM4 SerDes and Class C/D Compliance for IEEE 1588 Synchronization

IRVINE, Calif., Nov. 06, 2025 (GLOBE NEWSWIRE) -- Skyworks Solutions, Inc. (Nasdaq: SWKS), an innovator of high-performance analog and mixed-signal semiconductors connecting people, places and things, today announced a new family of ultra-low jitter programmable clocks designed to meet the increasing demands of next-gen connectivity. The SKY63101/02/03 Jitter Attenuating Clocks and SKY69001/02/101 NetSync™ Clocks leverage Skyworks’ proven DSPLL® and MultiSynth™ timing architecture and Skyworks’ advanced Bulk Acoustic Wave (BAW) technology to deliver breakthrough performance in low-jitter timing applications.

Together these new clocks redefine the benchmark for wireline, wireless, and data center timing solutions. The SKY63101/02/03 clocks provide industry-leading Synchronous Ethernet clock jitter of just 17 femtoseconds for 224G PAM4 SerDes, making them suitable for wireline and data center applications such as 800G/1.2T/1.6T optical networking and Data Center Interconnect (DCI) optical links. 

The SKY69001/02/101 clocks deliver best-in-class CPRI clock phase noise of -142 dBc/Hz at 100 kHz offset and support for IEEE 1588 Class C/D synchronization leveraging Skyworks AccuTime™ 1588 software, making them well-suited for wireless applications such as 5G and next-generation 6G massive MIMO radios. 

“Skyworks is committed to being an innovation leader in the timing industry,” said James Wilson, vice president and general manager at Skyworks. “By combining our advanced BAW technology with industry-leading DSPLL and MultiSynth timing architectures, these devices represent a significant leap forward in performance, reliability and integration. We are excited to bring these groundbreaking products to the market and support the evolving needs of 5G/6G networks, wireline and data center communications.” 

Skyworks is a recognized leader in BAW technology, known for manufacturing high-volume BAW GHz filters across consumer, IoT and infrastructure applications. Skyworks’ expertise in BAW technology has been instrumental in advancing 5G and Wi-Fi radio front-end solutions, leveraging silicon-based fabrication processes to ensure high performance and reliability in these critical applications.

At the heart of every Skyworks BAW filter is a multi-GHz, high Q-factor, low phase noise BAW micro-resonator. Skyworks’ newest timing products leverage this BAW frequency reference to eliminate the need for external quartz crystal, XO and VCXO references, minimizing bill of materials (BOM) count and complexity while improving clock jitter and overall system reliability.

The SKY69001/02/101 and SKY63101/02/02 family of products feature exceptional multi-channel noise isolation and on-chip power supply noise rejection, enabling a single device to generate multiple, non-related frequencies without compromising jitter, phase noise and spurious performance.

The SKY69001/02/101 and SKY63101/02/02 products share a common footprint and application programming interface (API), making it easy for designers to transition between using a jitter attenuating clock and a network synchronizer depending on system-level timing requirements. The SKY63101/02/03 and SKY69001/02/101 clocks are factory and field-programmable using integrated flash memory, enabling the devices to boot up with a preconfigured frequency plan and support easy in-field reconfigurability. These features enable system designers to develop a single hardware solution and tailor the solution for each application fully in software.

The SKY69001/02/101 and SKY63101/02/02 family of products have also been optimized to work in challenging environmental conditions. All these new devices support a -40 to +95°C ambient temperature range, making them ideal for non-temperature-controlled applications like wireless base stations. Typical power consumption is 1.2W, more than 60% lower than traditional solutions.
