Supply voltage tolerance is 2.25 V to 3.6 V, so the same BOM line works across 2.5 V and 3.3 V rails without a separate regulator — just confirm the output swing meets the receiver's VIH/VIL at the lower rail. ## Industrial temperature range and MEMS reliability ## Active lifecycle — sourcing through independent distribution No stock-holding claim — every order is quoted to order.","metaTitle":"DSC1121CI1-050.0000 MEMS XO 50 MHz CMOS - Microchip","metaDescription":"Active MEMS oscillator, 50 MHz CMOS output, ±50 ppm stability, -40°C to 85°C, 6-SMD.
