The enable/disable function lets firmware gate unused outputs to save power. The supply voltage spans 2.25 V to 3.6 V, so the oscillator can run from a common 2.5 V or 3.3 V rail without an intermediate LDO. The 0.90 mm seated height keeps it compatible with mezzanine-card stack-ups.","metaTitle":"DSC400-1111Q0091KI1 MEMS XO – 4 Outputs, LVCMOS, Active","metaDescription":"Microchip DSC400-1111Q0091KI1: MEMS-based XO, 4 LVCMOS outputs (12/24/48/14.25 MHz), ±50 ppm stability, -40 to +85°C, 20-VFQFN.
