The enable/disable function (E/D) lets the output be tri-stated for power-down or test modes, controlled by a logic-level pin. This is useful in multi-clock systems where the oscillator can be gated off during sleep states without removing the supply rail. ## Military temperature grade and MEMS reliability For a 20 MHz clock, that translates to ±500 Hz maximum deviation — tight enough for most MCU and FPGA clock inputs without external trimming. Housed in a 6-VDFN package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm. This is a current-design-eligible part from Microchip.","metaTitle":"DSC1121BM2-020.0000 MEMS XO 20 MHz CMOS - Microchip","metaDescription":"Active MEMS oscillator, 20 MHz CMOS output, 2.25-3.6V supply, -55 to +125°C.
