The DSC400-0101Q0114KI2T is an active MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two independent LVCMOS output frequencies: 12 MHz and 12.888 MHz. The base resonator is MEMS, which offers faster start-up and better shock/vibration immunity compared to quartz crystal oscillators. ## Frequency stability and temperature range Rated at ±25 ppm frequency stability over the full -40°C to +85°C industrial temperature range — this holds the output clock within 0.3 ppm/°C typical, sufficient for 100BASE-TX Ethernet and USB full-speed without an external VCXO. Housed in a 20-VFQFN exposed pad package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — the exposed pad must be soldered to a thermal land on the PCB; a 0.50 mm pitch stencil aperture and via-in-pad pattern are recommended for reliable solder-joint formation and heat dissipation.","metaTitle":"DSC400-0101Q0114KI2T MEMS XO – 12 MHz & 12.888 MHz, ±25 ppm","metaDescription":"Microchip DSC400-0101Q0114KI2T dual-output MEMS oscillator: 12 MHz + 12.888 MHz, ±25 ppm stability, LVCMOS, 2.25-3.6 V, -40 to +85°C.
