The 2.25V to 3.6V supply range lets it run directly from a 2.5V or 3.3V rail without an intermediate regulator. ## Frequency stability and enable/disable control Absolute Pull Range is ±50 ppm, which sets the frequency accuracy over the full temperature and voltage range — tighter than commodity ±100 ppm oscillators, so serial protocols like RS-485 or CAN maintain bit timing margin across the -55°C to 125°C span. Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that suits space-constrained PCBs in handheld or embedded modules. The DSC1121 series remains a current design-in choice for new timing trees.","metaTitle":"DSC1121CM1-005.5296 MEMS XO – 5.5296 MHz, CMOS, Active","metaDescription":"Microchip DSC1121CM1-005.5296: MEMS-based standard XO, 5.5296 MHz CMOS output, 2.25V–3.6V supply, -55°C to 125°C.
