SiT1421中文资料High frequency, -55°C to 125°C, Active Resonator Drop-In Replacement for 4-pin SMD XTAL数据手册SiTime规格书

描述 Description

The XCalibur™ SiT1421 active resonator is a drop-in replacement for 4-pin SMD quartz crystal resonators with wide temperature operation. Compared to traditional crystal resonators, XCalibur resonators have better reliability and better immunity to shock, vibration, and EMI. This resonator provides industry-best 0.1 ppb/g vibration sensitivity, 10,000 g shock and 70 g vibration resistance. As an active MEMS device, the SiT1421 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. This device also features a wide frequency range, excellent stability, and short lead times for a range of high temperature applications.
