Begins Mass Production of Differential Clock Crystal Oscillators, Enabling Low Noise, Low Power Solutions for AI Server Data Communication
Kyocera Corporation announced the launch of the "X Series" differential clock oscillators, which achieve industry-leading *1 30 fs (femtosecond) low phase jitter and low noise. Mass production began in January 2026. In response to growing demand created by the widespread adoption of generative AI and the ongoing expansion of the AI server market, the company plans to increase production capacity to 2 million units per month from June. This strategic initiative will enable Kyocera to effectively address the evolving needs of this rapidly expanding sector.
*1 For differential clock crystal oscillators at a frequency of 312.5MHz and 3.3V
Development Background
In light of the expanding 5G network infrastructure and the increasing prevalence of AI data centers, there has been a notable surge in demand for enhanced data communication capabilities in network equipment and servers. In high-speed communication, noise and timing misalignment can result in bit errors. Consequently, there is an increasing demand for highly precise differential clock crystal oscillators with "low phase jitter characteristics," meaning extremely small timing deviations in the signal. The "X Series," newly commercialized by Kyocera, is a differential clock crystal oscillator that achieves industry-leading*1 low noise with a phase jitter of 30 fs.

Features
Achieves Industry-Leading 30 fs Low Phase Jitter
Achieving a 30fs phase jitter required a blend of high-quality crystals and advanced ICs. The Kyocera X Series has achieved this industry-leading level through the integration of proprietary semiconductor photolithography, a compact design approach with the plasma CVM fabrication method, and high-performance ICs. Compared to conventional products running at the same frequency, the X Series reduces phase jitter by about 25%, thereby significantly reducing errors in high-speed communication.
Significantly Reduced Power Consumption by Approximately 42% Compared to Conventional Products
By incorporating a new differential-output oscillator IC, Kyocera has greatly reduced power consumption, enabling notable energy savings in AI servers and other high-performance computing equipment. For the 156.25 MHz (LV-PECL output) configuration, the X Series consumes 29 mA, a 42% reduction compared to the 50mA typical of conventional products.
Suitable For a Wide Range of Ultra-Small Sizes From 2016 to 3225
X Series clock oscillators also adopt Kyocera's unique platform structure, which combines a fixed head unit (consisting of a quartz crystal and an IC) with a metal-wired bottom base, enabling support for a wide range of sizes from ultra-small 2016 to 3225.
Applications
AI servers, optical transceivers, storage applications, automotive ADAS equipment
