JWT 312.500MHz Differential Oscillator Launches

With the explosive growth of AI large models, data center infrastructure is undergoing an industrial evolution from 800G to 1.6T and even 3.2T rates. JWT achieved a breakthrough in independently developing the 312.5MHz differential oscillator, becoming one of the few manufacturers capable of supplying ultra-high frequency differential crystal oscillators.

Today, let’s analyze the features of this 312.5MHz differential crystal oscillator launched by JWT.

1. Ultra-Low Phase Jitter

Currently, the typical phase jitter (12KHz～20MHz) of the oscillator across the full temperature range can reach 35fs.

2.Full Temperature Range ±20PPM Frequency Stability

This product achieves a frequency stability of ±20ppm over the entire temperature range, ensuring the frequency doesn’t drift under any operating conditions.

3.Strong Anti-Interference

Supports LVDS/LVPECL output, providing better common-mode noise rejection, resulting in purer and more stable signals in complex environments.

4. Miniaturization: Suitable for High-Density Integration

The space reserved for the crystal oscillator on the circuit board is extremely limited, making the 2.0×1.6mm miniature package essential. This compact size helps free up valuable space for other components on the cramped optical module circuit board.

JWT has been committed to the independent research and development of lithography technology.

We have achieved success not only with the 312.5MHz high-frequency fundamental solution but also with low-frequency solutions such as the 32.768kHz oscillator.

Facing the upcoming demand for 625MHz ultra-high frequencies in the 3.2T era, we will continue our independent R&D efforts as always  to drive the development of crystal oscillators toward even greater frequency stability.
