1至150 MHz,扩频,扩展温度(-55°C至125°C)

Endura™SIT9045扩频振荡器设计用于恶劣环境,是高可靠性航空航天和防御应用的理想选择。该基于MEMS的SSXO在0.1 ppb /时具有超低的加速度灵敏度/g以及高达125°C的高温操作。

This device reduces EMI (up to 30 dB) by offering two techniques: spread spectrum clocking and rise/fall time adjustment of the clock signal, ensuring emissions compliance with maximum flexibility and minimum engineering effort. The SiT9045 is available in three industry-standard packages to replace quartz products without any board design changes.

The SiT9045 conforms to MIL-PRF-55310, MIL-STD-883, and AEC-Q100 specifications.
