The wide supply range of 2.25V to 3.6V means it runs directly from a 3.3V or 2.5V rail without an extra LDO — the internal regulator handles the MEMS core voltage. Housed in a 20-VFQFN with exposed pad, the 5.00 mm × 3.20 mm footprint is compact enough for space-constrained designs, but the exposed pad requires a thermal via pattern under the package for proper solder-joint reliability and heat sinking. The 0.90 mm height keeps it low-profile for mezzanine card stacking.","metaTitle":"DSC400-1111Q0090KI1 MEMS XO – 4-Output LVCMOS Clock","metaDescription":"Microchip DSC400-1111Q0090KI1: MEMS-based XO, 4 LVCMOS outputs (10/27/148.5/125 MHz), ±50 ppm stability, -40°C to +85°C, 20-VFQFN.
