The 6-SMD no-lead package (3.20mm x 2.50mm, 0.90mm seated height) is a standard footprint shared across the DSC1121 family, so a single PCB layout can accommodate frequency variants without a board spin.","metaTitle":"DSC1121CM1-030.0000 MEMS XO – 30 MHz CMOS, Active","metaDescription":"Microchip DSC1121CM1-030.0000: 30 MHz MEMS oscillator, CMOS output, ±50 ppm stability, 2.25-3.6V supply, -55 to 125°C.
