Yangxing Technology's TCXO/OCXO clock solutions enable high-precision synchronization of 5G base stations.

As 5G networks transition from large-scale deployment to precision performance enhancement, base station systems now demand significantly higher frequency accuracy, time synchronization stability, and long-term operational reliability from reference clock sources. Crystal oscillators have become critical foundational components determining the performance limits of 5G networks. Leveraging decades of expertise in clock frequency devices, YXC Yangxing Technology has developed a comprehensive 5G base station clock solution encompassing both TCXO and OCXO series technologies. 

I. Core Clock Performance Requirements for 5G Base Stations

1. Requirements for frequency stability under high-frequency bands and high-order modulation

5G networks extensively utilize mid-to-high frequency bands and adopt advanced modulation techniques like 256QAM, which significantly enhance data rates and capacity while also making the system more sensitive to short-term stability of local oscillator frequencies and phase noise.

Minor frequency shifts will directly affect:

• Modulation accuracy (EVM)

• Demodulation bit error rate (BER)

• System Capacity and Edge Performance

Therefore, reference clocks at all levels within 5G base stations must exhibit high stability and low noise output characteristics.

2. Time Synchronization Requirements for TDD and Cooperative Communication

In 5G TDD networks, time synchronization errors between base stations must be strictly controlled within an extremely narrow range to prevent uplink and downlink signal interference. Meanwhile, technologies such as CoMP, carrier aggregation, and multi-base station collaborative communication require multiple base stations to maintain high synchronization across both time and frequency dimensions, further increasing the demand for system clock synchronization precision.

3. Requirements for clock reliability under long-term operation and complex environments

5G base stations are typically deployed in outdoor or complex data center environments, requiring crystal oscillators to maintain stable operation over extended periods within the temperature range of-40°C to +85°C, while demonstrating excellent aging characteristics and consistent performance.

II. Application of YXC Temperature-Tuned Crystal Oscillator YSO510TP Series in 5G Base Stations
