High Frequency, High Temperature Active Resonator Drop-In Replacement for 4-pin SMD XTAL

Login

The XCalibur™ SiT1419 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 SiT1419 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 applications.
