With the continuous development and widespread application of ChatGPT technology, the AI server market in our country is growing at a rapid rate (it is estimated that by 2023, our national server market will expand to 30.8 billion US dollars). This strong market trend has further driven a significant increase in AI server shipments, which has also triggered a rapidly growing demand for key components such as crystal oscillators.

Currently, oscillators used in AI servers are mainly differential oscillators. This is mainly due to its advantages compared to the single-ended output oscillators. Differential oscillators can generate high-quality differential clock signals, have excellent resistance to common-mode interference and noise, and can provide large-amplitude and high-frequency clock signals, especially suitable for driving long lines.

These characteristics enable differential oscillators to better meet the stringent requirements for stable and high-performance operation of AI servers. Therefore, using differential oscillators as their reference clock signal source is a very reasonable choice.

In the contrast between differential output and single-ended output, all circuits require a complete current loop to function properly. For a single-ended circuit, the signal is transmitted to the receiver through a single wire, and the signal is the level difference between the ground and the transmission in a wire.

The disadvantage of this approach is that the whole circuits linked will be affected if there is noise on the ground. Differential signaling uses two wires or PCB traces. The second wire or trace provides a return path for the current, while 180 degrees phase difference exists between the signal on the wire (the complementary signal) and the true signal. The differential signal loop is specially designed for this circuit, effectively reducing the risk of interference.

The YXC differential oscillator series recommended for AI servers is YSO230LR. Commonly used frequencies include 50MHz, 125MHz, and 156.25MHz.

The YSO230LR series is a differential output oscillator with the following product parameters and advantages:

Wide frequency range from 13.5MHz to 200MHz, meeting the common frequencies need for AI servers.

High precision and stability, the frequency difference is controlled at ±30ppm within the full temperature range.

Support differential signal (LVDS/LVPCECL/HCSL) output and have strong anti-interference ability.

Low jitter, typically 0.1ps .

Adapt to the industrial temperature range and meet the usage requirements of -40~85℃.

Various package sizes are available, including 7050/5032/3225/2520. The 3225/2520 package is recommended to save PCB space more effectively. The features of this series make YXC differential oscillator an ideal choice for AI server design.
