AI servers are high-performance servers specifically designed to execute computation-intensive tasks such as artificial intelligence (AI), machine learning (ML), and deep learning (DL). They can learn how to efficiently operate servers by collecting, analyzing, and simulating data, and can also adjust server performance according to different applications and user requests, thereby providing better server performance. AI server hardware requires stable clock signals as a benchmark to ensure computational accuracy and stability, and crystal oscillators are one of the key components providing such benchmark signals.

Regarding AI servers:

As the engine of computing power, the growth in computing power demand will lead to a rapid increase in the demand for AI servers.

Common crystal oscillator frequencies used in AI servers include:

32.768kHz: Mainly used in Real-Time Clock (RTC) modules for time management in computer systems. It is recommended to use Interquip's 9CAA32768 (3215 package, 32.768KHz), SMLF-1610 (32.768KHz), and other low-frequency tuning fork crystals.

14.318MHz: Mainly used for clock signals in graphics cards and other video-related devices. It is recommended to use Interquip's 5YAA14318 (14.318MHz) surface-mount crystal oscillator.

24MHz, 25MHz, 26MHz: Mainly used for clock signals in motherboard chipsets, CPUs, and other devices. It is recommended to use Interquip's SMCE-2016 (16MHz~96MHz) custom frequency surface-mount crystal oscillator.

In computing servers, the stability and accuracy of clock signals are particularly critical as they affect the computational performance and stability of the entire system. Crystal oscillators (quartz crystal resonators and oscillators) can provide precise clock signals, hence their widespread application in computing servers.

Regarding optical modules:

Optical modules are optoelectronic devices that perform optical-to-electrical and electrical-to-optical conversion. The transmitting end of the optical module converts electrical signals into optical signals, and the receiving end converts optical signals back into electrical signals. The transmitting end OLT and receiving end ONU equipment of optical modules require extensive use of crystal oscillators. In optical modules, the light waves generated by lasers need to have stable frequencies and wavelengths, which necessitates the use of quartz crystal resonators as frequency control components to precisely lock the laser's frequency within a specified range.

For example, in 10G-PON ONU optical modem routers, LVPECL/LVDS differential output crystal oscillators with frequencies such as 125MHz, 155.52MHz, and 156.25MHz are often used. Moreover, the operating temperature requirements for crystal oscillators are very high, typically requiring at least -40℃ to +105℃.
