New SKY53510/80/40 Family of Clock Fanout Buffers are Purpose-Built for Data Centers, Wireless Networks, and PCIe Gen 7 Applications

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—7x7mm (10 outputs), 6x6mm (8 outputs), and 5x5mm (4 outputs)—these devices are pin-compatible with industry-standard layouts for easy integration and multi-sourcing.

“Skyworks is pushing the boundaries of clock tree signal integrity,” said James Wilson, vice president and general manager of Mixed Signal Solutions at Skyworks. “Our new SKY53510/80/40 buffer family offers unmatched jitter performance and format flexibility—empowering designers to meet the demands of today’s most advanced communication and computing platforms.”

Designed for High-Speed Applications

SKY53510/80/40 buffers are well suited for:

• PCIe Gen 3 through Gen 7
• 56G/112G/224G SerDes
• 5G/6G mMIMO radio systems
• SyncE and broadcast video
• Medical imaging and aerospace/defense

These devices support input clock slew rates down to 0.75V/ns and output levels of 1.8V, 2.5V, and 3.3V—enabling robust PCB designs with minimal signal integrity challenges such as reflection, crosstalk, and ground bounce.

Key Features

The SKY53510/80/40 features include:

• Ultra-low additive RMS phase jitter: 35 fs at 156.25 MHz, 3 fs at 100 MHz (PCIe Gen 7)
• Universal format translation: LVPECL, LVCMOS, LVDS, HCSL, CML, SSTL, HSTL, and AC-coupled single-ended inputs; selectable LVPECL, LVDS, HCSL, or tristate outputs
• Low power operation: Separate core/output voltage supplies (1.8V, 2.5V, 3.3V)
• Integrated LDOs: >70 dBc PSRR for noisy environments
• Wide temperature range: -40°C to +95°C ambient (-40°C to +105°C board)
• Low noise floor: -166 dBc/Hz for SyncE 156.25 MHz applications

The devices are ideally suited for pairing with Skyworks’ Si551x Network Synchronizers, SKY63104/5/6 family of Jitter Attenuating Clocks and SKY62101 Ultra-low Jitter Clock Generators to deliver complete clock tree solutions that meet the demanding requirements of next-generation 6G wireless infrastructure, 800G/1600G networking infrastructure, and AI data center applications that utilize 112G/224 PAM4 SerDes technology.
