The MEMS resonator means no quartz crystal to age or shock-misalign; it is a sealed silicon die inside the 6-VDFN package. Runs off a 2.25V to 3.6V supply, so it works on a 2.5V or 3.3V rail without a separate regulator. If your system sees under-hood heat or a cold start, this grade has margin. ## Sourcing and lifecycle — active, quoted to order ## Package and board-fit — 6-VDFN with exposed pad 6-VDFN package, 7.00 mm x 5.00 mm body, 0.90 mm seated height. Surface-mount only — no socket option. The 0.90 mm height is low enough for 1U rack-mount card spacing.","metaTitle":"DSC1121AI2-053.1250T – 53.125 MHz MEMS XO, CMOS, Active","metaDescription":"Microchip DSC1121AI2-053.1250T: 53.125 MHz MEMS XO, CMOS output, ±25 ppm, 2.25–3.6V, -40°C to 85°C, 6-VDFN.
