The ±25 ppm frequency stability holds across the full temperature and voltage range, so a 3.3333 MHz serial clock stays within 83 Hz of nominal at 125°C — tight enough for most UART and CAN transceiver timing. ## Package, footprint, and board mounting Housed in a 6-SMD, no-lead package measuring 2.50mm x 2.00mm with a seated height of 0.90mm. The 6-pad land pattern fits a standard 2.0 x 2.5 mm oscillator footprint — no via-in-pad required, but the small pad area means a solder stencil with 0.12 mm thickness and 1:1 aperture-to-pad ratio is recommended for consistent fillet formation.","metaTitle":"DSC1121DM2-003.3333 MEMS XO – 3.3333 MHz, AEC-Q100","metaDescription":"Microchip DSC1121DM2-003.3333: 3.3333 MHz MEMS XO, CMOS output, ±25 ppm stability, AEC-Q100, -55°C to 125°C.
