Grand New Release! Saisi Ultra-Low Jitter Differential Crystals Empower High-Speed Interconnection of AI Servers and Optical Modules

The explosive growth of AI computing power fuels comprehensive technological upgrades of computing infrastructure. Next-gen AI servers and 800G/1.6T optical modules impose stricter requirements on timing accuracy. Saisi officially launches a new lineup of ultra-low jitter differential crystals, delivering high-performance timing solutions for high-speed interconnection of AI servers and optical modules.

1. High-Speed Interconnection: Clock Jitter Becomes Core Bottleneck

AI servers are advancing into a new stage of scale-out, scale-up and scale-across development. Exponentially surging massive data interaction between GPUs, cabinets and data centers drives rapid iteration of optical modules toward 800G, 1.6T and higher speeds. Goldman Sachs estimates the global optical module market will reach 37 billion US dollars by 2027, with 800G/1.6T high-speed optical modules dominating the market. Technological upgrading in high-speed interconnection has entered a critical phase.

As core components supplying high-precision clock signals and frequency control for optical modules and AI servers, crystals directly determine the upper limit of system operation performance. Acting as the heartbeat of systems during high-speed data transmission, clock jitter refers to minor deviations of clock edges from ideal timing. Such deviations get amplified continuously on 112G/224G SerDes and higher-speed interconnection links, hindering accurate signal identification at receiving ends and undermining system reliability and performance. Reducing clock jitter builds clearer and more stable channels for data transmission. Elevating jitter precision from picosecond to femtosecond level is pivotal to unlocking next-generation high-speed interconnection systems.

2. New Launch: Saisi Ultra-Low Jitter Differential Crystals

Leveraging profound technological expertise in high-frequency and ultra-low jitter clock synchronization, Saisi unveils new ultra-low jitter differential crystals to offer premium timing solutions for AI servers and optical modules.

Femtosecond-level Precision: Ordinary crystals feature 1-3ps jitter, while Saisi cuts the typical phase jitter of differential crystals to 44fs@156.25MHz (1fs=0.001ps), achieving a remarkable performance leap. The breakthrough specification fully meets stringent timing demands of 400G/800G/1.6T optical modules and next-gen AI server interconnection.

Strong Anti-interference Capability: Traditional timing solutions suffer electromagnetic interference and degraded signal integrity during long-distance transmission amid high-density, high-power consumption electromagnetic environments of AI servers. Boasting outstanding anti-interference performance and low phase noise, Saisi differential crystals maintain pure and stable clock signals in long-distance transmission and harsh electromagnetic scenarios, securing system signal integrity fundamentally.

Diversified Package Sizes: To adapt to tight space constraints of optical modules and AI accelerator cards, multiple mainstream SMD packages are available, including 2.5×2.0mm, 3.2×2.5mm, 5.0×3.2mm and 7.0×5.0mm. Miniature packages like 2520 and 3225 retain 44fs ultra-low jitter while reserving ample space for heat dissipation and layout, ideal for high-integration designs.

Full Compatibility: The product series covers a wide frequency range from 25MHz to 625MHz, covering mainstream frequencies such as 156.25MHz and 312.5MHz for optical modules and servers. It supports multiple differential output modes including LVPECL, LVDS and HCSL, operates at 1.8V to 3.3V, and adopts low-power design. It can be seamlessly integrated into diverse systems to boost integration efficiency and overall energy efficiency.

3. Empower the Future: Accelerate Evolution of AI and All-optical Interconnection

Driven by computing power revolution and massive data flow, the precision and stability of clock signals stand as core competitiveness for next-generation AI and communication infrastructure. As AI large-scale models grow to trillion-parameter scale and data center bandwidth keeps expanding, industrial timing requirements will keep rising.

Saisi ultra-low jitter differential crystals serve as reliable timing cores for current 800G/1.6T high-speed interconnection, and cater to technical evolution demands of 3.2T and higher speeds in advance. Its femtosecond precision, robust anti-interference and high integration perfectly fit future development trends of high-density, low-power and high-reliability data centers.

Going forward, Saisi will continuously break boundaries in timing technology. With extreme precision and dependable performance, we will collaborate with industry partners to embrace the new era of intelligent interconnected everything.
