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.
第3E层OCXOs
高精度祖母绿OCXOs提供±5至±8 ppb的稳定性，1至220兆赫的频率，以及三个标准OCXO脚印除了最小的9 x 7毫米的脚印。在新兴的5G和IEEE1588同步应用中，这些设备可以作为传统石英OCXO的替代品，同时提高系统的整体性能和健壮性。
- 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
- 可编程平台可缩短交付周期
- On-chip power supply noise filtering, eliminates dedicated LDO
- No activity dips or micro jumps

Stratum 3E DCOCXOs
高精度祖母绿DCOCXOs（数字控制OCXOs）提供±5至±8 ppb的稳定性、1至220 MHz的频率和业界最小的9 x 7 mm的占地面积。这些设备可用于取代新兴5G和IEEE 1588同步应用中的传统石英VCOCXO，同时提高整体系统性能和鲁棒性。
- I2C digital frequency tuning eliminates board noise
- 10倍的动态稳定性（150 ppt/°CΔF/ΔT），抗气流和热冲击
- Unmatched ease-of-use, eliminates restrictions on PCB placement, no mechanical shields needed
- 可编程平台可缩短交付周期
- On-chip power supply noise filtering, eliminates dedicated LDO
- No activity dips or micro jumps
