The MEMS resonator replaces the quartz crystal, eliminating cold-start frequency drift and improving shock/vibration tolerance — a real advantage on a factory floor or in an engine bay where a crystal can crack or start slow. ## Package and board-fit checklist Housed in a 6-VDFN package measuring 5.00mm x 3.20mm with a seated height of 0.90mm. Surface-mount, tape-and-reel delivery. The enable/disable pin lets you gate the output for power savings — the disable current max is 22 mA versus 35 mA active. No special layout tricks: standard decoupling cap near the supply pin, keep the output trace short to the load.","metaTitle":"DSC1121BI1-020.0000T MEMS Oscillator 20 MHz CMOS - Microchip","metaDescription":"Active XO (Standard) MEMS oscillator, 20 MHz CMOS output, enable/disable, -40°C to 85°C, 2.25-3.6V supply.
