• Why OCXO?

  • Ultra-low jitter (20 fs RMS) ensures precise signal generation and analysis.

  • Stable frequency under temperature variations guarantees measurement repeatability.

3. Military & Aerospace (COTS Applications)

• Function: Used in secure communication systems, GPS receivers, and electronic warfare (EW) systems.

• Why OCXO?

  • Resistant to environmental stress (e.g., vibration, shock, and extreme temperatures).

  • Low phase noise prevents signal degradation in encrypted communications

4. Telecommunications & Network Synchronization

• Function: Ensures clock synchronization in 5G base stations and optical transport networks (OTN).

• Why OCXO?

  • Minimizes timing errors in high-speed data transmission.

  • Long-term stability (±50 ppb) reduces the need for frequent recalibration.

5. High-End Computing & Data Centers

• Function: Provides timing for FPGA/ASIC clock distribution.

• Why OCXO?
