Emerald Platform™ Stratum 3E OCXOs (oven controlled oscillators) and DCXOs (digitally controlled OCXOs) are engineered to solve the long standing challenges of legacy quartz OCXOs which are sensitive to environmental conditions, require protective components, and are difficult to procure and use. Emerald OCXOs are designed to provide better dynamic performance, unmatched ease-of-use, the smallest size, and shorter lead times.
Stratum 3E OCXOs
High-precision Emerald OCXOs offer ±5 to ±8 ppb stability and 1 to 220 MHz frequency in the industry's smallest OCXO footprint at 9 x 7 mm. These devices are ideal for emerging 5G and IEEE 1588 synchronization applications that require robust system performance.
- 10 times better dynamic stability (50 ppt/°C ΔF/ΔT), resistant to airflow and thermal shock
- Unmatched ease-of-use, eliminates restrictions on PCB placement, no mechanical shields needed
- Programmable platform enables shorter lead time
- On-chip power supply noise filtering, eliminates dedicated LDO
- No activity dips or micro jumps

Stratum 3E DCOCXOs
High-precision Emerald DCOCXOs (digitally controlled OCXOs) offer ±5 to ±8 ppb stability, 1 to 220 MHz frequency, and the industry's smallest 9 x 7 mm footprint. These devices can be used to replace legacy quartz VCOCXOs in emerging 5G and IEEE 1588 synchronization applications while improving overall system performance and robustness.
