SiT1418数据手册SiTime中文资料规格书

描述 Description

The XCalibur™ SiT1418 active resonator is a drop-in replacement for high temperature quartz crystal resonators. As an active MEMS device, the SiT1418 eliminates issues related to crystal resonators, such as cold startup under all conditions, crystal motional series resistance (ESR) compensation, negative resistance testing, and the need for tuning capacitors. One XCalibur active resonator can drive up to two clock inputs. Compared to traditional crystal resonators, XCalibur resonators have better reliability and better immunity to shock, vibration, and EMI. The SiT1418 provides industry-best 0.1 ppb/g vibration sensitivity, 10,000 g shock and 70 g vibration resistance. This device also features a wide frequency range, excellent stability, and short lead times for industrial, medical, automotive, avionics, and other high-temperature applications.
