The wide voltage range simplifies use across multi-rail designs without a separate regulator for the oscillator. Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The no-lead construction requires a solder-paste stencil with aperture matching the pad geometry.","metaTitle":"DSC1121CM1-027.0000T MEMS Oscillator – 27 MHz, AEC-Q100","metaDescription":"Microchip DSC1121CM1-027.0000T: 27 MHz MEMS XO, CMOS output, AEC-Q100, -55°C to 125°C.
