Advanced features and application areas of Epson SPXO crystal oscillator SG2520EGN/SG2520VGN

    In the era of continuous technological advancement, crystal oscillators are indispensable components in electronic circuits, and their performance has a direct impact on the stability and efficiency of various devices. Especially high-frequency and low jitter crystal oscillators are crucial for the new generation of communication technology and high-speed data processing. EPSON's SG2520EGN and SG2520VGN crystal oscillators have become the focus of attention for electronic engineers due to their excellent technical specifications and compact design. Below, we will delve into the characteristics and applications of these two crystal oscillators.

一、 Product feature analysis

1. Frequency and size

SG2520EGN: This crystal oscillator has a frequency of 156.250MHz and is packaged in a miniaturized 2520 (size 2.5x2.0x0.84mm), which is beneficial for saving circuit board space and improving integration. SG2520VGN: Similar to SG2520EGN, the frequency is also 156.250MHz, but the output type is LVDS. This differential output mode helps minimize the impact of noise. The frequency tolerance is ± 50ppm, which can provide accurate and stable clock signals to ensure the normal operation of the equipment and the accuracy of data transmission.

2. Low jitter characteristics

These crystal oscillators have ultra-low phase jitter (up to 50fs), which means that the periodic changes in a very short period of time are very small. This performance is crucial for high-precision applications, such as in servers, data centers, and high-speed DA/AD converters.

3. Working temperature and stability

These devices can operate stably within a temperature range of -40 to+85 ° C, with a frequency tolerance of ± 50ppm. The high temperature drift and high stability make it suitable for use in harsh environments, ensuring the reliability and data accuracy of the equipment.

4. Power supply voltage and power consumption

The power supply voltage range is 2.375 to 2.625 V, and the power consumption current is ≤ 60.0 mA. The lower power supply voltage and power consumption make these two crystal oscillators perform excellently in portable devices with high energy-saving requirements and battery powered applications.

二、 Application Fields

1. Communication network

Due to the fast, broadband, and noise minimizing transmission environment required by high-speed networks such as 6G, SG2520EGN and SG2520VGN are highly suitable as reference clock oscillators in 5G and 6G communication networks due to their high frequency and low jitter characteristics, supporting 400G optical module communication.

2. Optical module

The implementation of the Internet of Things and ADAS has led to a significant increase in data traffic, requiring crystal oscillators to have low jitter and high stability. The SG2520 series can significantly improve the performance of optical modules in these applications.

3. Automotive Electronics

Advanced Driver Assistance Systems (ADAS) in modern cars require high-performance sensors and timing components. The SG2520 series crystal oscillator is widely used in various vehicle applications ranging from engine management systems to autonomous driving technology due to its compact design and superior electrical characteristics.

4. Measuring instruments

Precision measuring instruments require precise time benchmarks to ensure the accuracy of data. These crystal oscillators are an ideal choice for both precise synchronization required for industrial automation and fine control of laboratory instruments.

By understanding the technical characteristics and application scenarios of EPSON SG2520EGN and SG2520VGN crystal oscillators, professional engineers can more accurately select and use these two excellent crystal oscillator products, thereby promoting the development and optimization of related technological projects.
