Ultra-low jitter clock buffers

31 October 2025 Telecoms, Datacoms, Wireless, IoT

Skyworks Solutions recently unveiled the SKY53510/80/40 family of clock fanout buffers designed to meet the stringent timing demands of next-generation high-speed infrastructure.

With the rollout of PCIe Gen 7 and the continued expansion of AI, cloud computing, and 5G/6G networks, timing precision has become a critical enabler of performance. The SKY53510/80/40 family offers a scalable, low-jitter clock buffer solution that simplifies design and enhances signal integrity across a wide range of platforms. For system architects and hardware designers, this means faster time to market, reduced engineering overhead, and the ability to future-proof designs for emerging standards like PCIe Gen 7 and 6G wireless.

The SKY53510/80/40 family features a 3:1 input multiplexer (including crystal input), one single-ended output, and up to 10 differential outputs. Offered in compact thermally enhanced QFN packages (7 x 7 mm (10 outputs), 6 x 6 mm (8 outputs), and 5 x 5 mm (4 outputs)), these devices are pin-compatible with industry-standard layouts for easy integration and multi-sourcing.

These devices support input clock slew rates down to 0,75 V/ns and output levels of 1,8 V, 2,5 V, and 3,3 V, enabling robust PCB designs with minimal signal integrity challenges such as reflection, crosstalk, and ground bounce.
