Recently, with the significant increase in demand for artificial intelligence servers, the optical module market has shown strong growth momentum. It is predicted that the use of optical modules for AI servers will begin to significantly increase from the second half of 2023 and is expected to achieve a year-on-year growth rate of over 100% by 2024. It is worth noting that the AI server optical module needs to be used in conjunction with a high-end differential oscillator, which has a unit price about 10-20 times higher than that of ordinary servers or consumer electronics oscillators, but the corresponding gross profit margin is also higher, reaching more than 50-60%.、

The role of crystal oscillators in AI servers

An AI server is a high-performance computer specifically designed to handle tasks related to artificial intelligence. It has powerful computing and storage capabilities, and can quickly process large amounts of data and complex algorithms. Compared to traditional computing devices, AI servers have higher computing efficiency and lower energy consumption.

To ensure the synchronization timing and high-speed computing requirements of AI server system components, oscillators are an indispensable component responsible for providing reference clock signals and high-speed differential clock signals. With the continuous expansion of the global AI server market, oscillators, as the core components of AI servers, will usher in a new stage of development.

From a cost structure analysis, oscillators play a key role in AI servers, with their market size accounting for approximately 3-5% of the total cost of AI servers. According to predictions from various research institutions, the global AI server market is expected to reach a size of $62-97 billion by 2025.

In AI servers, crystal oscillators, as a key electronic component, play an important role in providing timing and frequency references for various electronic circuits or systems, ensuring the stability and performance of the server. In application scenarios, the CPU, memory, GPU, and other components of the server require stable clock signals to drive their operation, network interfaces require stable clock signals to ensure accurate data transmission and operation, storage controllers require stable clock signals to ensure that various components of the server run synchronously at a predetermined frequency, and power management requires precise clock signals to control the on/off time of the power supply, reduce energy consumption, and improve energy efficiency.

Common frequency points for AI servers: 25MHz, 50MHz, 100MHz, 125MHz, 156.25MHz. Epson recommends the differential programmable crystal oscillator SG3225VEN suitable for AI servers.
