The MEMS resonator replaces a quartz crystal, so the part is inherently more shock- and vibration-tolerant than a traditional XO — useful in industrial or mobile equipment where the board sees mechanical stress. ## Supply range and enable function Runs from 2.25 V to 3.6 V, covering the common 2.5 V and 3.3 V logic rails without a separate LDO. The Enable/Disable pin lets a system controller gate the clock — useful for power-saving in multi-rail designs or for disabling the oscillator during boundary-scan testing. ## Industrial temperature and package fit Rated -40°C to 85°C, so it works in outdoor telecom cabinets, factory-floor controllers, and engine-bay-adjacent electronics without a temperature grade downgrade.","metaTitle":"DSC1124BI5-148.5000T MEMS XO, HCSL, 148.5 MHz, Active","metaDescription":"Microchip DSC1124BI5-148.5000T: MEMS XO, HCSL output, 148.5 MHz, ±10 ppm, -40°C to 85°C, 6-SMD.
