Low Power Active Resonator Drop-In Replacement for 4-pin SMD XTAL
LoginThe XCalibur™ SiT1409 active resonator is a drop-in replacement for high frequency 4-pin SMD quartz crystal resonators. As an active MEMS device, the SiT1409 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 SiT1409 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 a range of applications.
