SiTime Precision MHz Super-TCXOs
SiTime MEMS precision oscillators deliver the most stable timing under stressors like airflow, rapid temperature change, shock, vibration, poor power supply, and EMI.
SiTime MEMS precision oscillators deliver the most stable timing under environmental stressors – airflow, rapid temperature change, shock, vibration, poor power supply, and EMI – in a small, robust package. These devices can be programmed to any combination of frequency, stability, voltage, and pull range within a wide range of parameters, eliminating the long lead times, customization costs, and reliability concerns associated with quartz TCXOs and OCXOs.
Super-TCXOs
Elite Platform® and Elite X™ Super-TCXOs are precision timing solutions with exceptional dynamic performance and rich features. These devices solve deep-rooted timing problems for telecom, networking, edge synchronization, and precision GNSS systems. By combining tight-stability with the robust package of a ceramic TCXO, SiTime Super-TCXOs replace legacy quartz OCXOs while increasing reliability, lowering power, and reducing size.
Features
- Tight stability (±0.01 ppm to ±2.5 ppm), 1 to 220 MHz
- Better dynamic stability than quartz (±0.5 ppb/°C ΔF/ΔT), resistant to airflow and thermal shock
- -40°C to 105°C operation uniquely enables fan-less outdoor equipment
- Lower power consumption (110 mW, 2.5V) for battery-operated edge equipment
- I2C digital frequency tuning eliminates external DAC and sensitivity to board noise
- On-chip power supply noise filtering eliminates dedicated LDO
Automotive TCXOs
SiTime’s AEC-Q100 automotive TCXOs are based on the Elite Platform™ and are engineered to deliver higher dynamic performance, reliability and robustness, making them ideal for autonomous driving systems. These 1 to 220 MHz precision devices with tight stability (±0.1 ppm to ±2.5 ppm) over AEC-Q100 Grade-2 temperature from -40°C to 105°C, solve deep-rooted timing problems in harsh automotive environments.
Features
- 30x better dynamic stability (1 ppb/°C ΔF/ΔT) than quartz, resistant to airflow and thermal shock
- AEC-Q100 Grade-2 -40°C to 105°C operation for high-temp environments
- Industry best G-sensitivity of 0.1 ppb/g
- Better shock resistance at 10,000g, vibration resistance at 70g
- Higher reliability at over 1 billion hours MTBF (< 1 FIT)
