Output frequencies are factory-programmed to 27 MHz, 50 MHz, 25 MHz, and 12 MHz — a common mix for a processor core clock, a USB interface, a serial transceiver, and a low-speed peripheral bus, all in one device. Supply voltage spans 2.25 V to 3.6 V, so the same part works on a 2.5 V or 3.3 V rail without a separate regulator. ## MEMS resonator versus quartz — the sourcing angle MEMS oscillators have inherently shorter lead times and better shock/vibration tolerance than quartz crystal oscillators, which can be a sourcing advantage when quartz supply tightens. Frequency stability is rated ±25 ppm total over the -20°C to 70°C commercial temperature range — tight enough for 10/100 Ethernet and USB full-speed without a TCXO, but not rated for extended-temperature outdoor or automotive use.","metaTitle":"DSC400-1111Q0081KE2 MEMS Oscillator – Quad LVCMOS Output","metaDescription":"Microchip DSC400-1111Q0081KE2 XO (Standard) MEMS oscillator: quad outputs 27/50/25/12 MHz, LVCMOS, ±25 ppm, 2.25-3.6V, 20-VFQFN.
