High-precision Emerald DCOCXOs (digitally controlled OCXOs) offer ±5 to ±8 ppb stability, 1 to 60 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.

• I2C digital frequency tuning eliminates board noise.
• 10 times better dynamic stability (40 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.
