That tight stability keeps the clock edge jitter low enough for 100 Mbps Ethernet PHYs, FPGA transceivers, and high-speed ADCs where a ±25 ppm oscillator would eat into the timing budget. ## Supply range and disable function The supply voltage covers 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without a separate LDO. There is no NRND or EOL notice on this part, so it is safe to design into a new BOM today. ## MEMS vs quartz — field-fit note If your board sees vibration from a fan, pump, or vehicle chassis, the MEMS die is less likely to fracture than a quartz blank. The 6-SMD package is a drop-in footprint for standard 7×5 mm oscillators — check the pad layout against your existing quartz XO land pattern before committing.","metaTitle":"DSC1121AL5-100.0000 – Microchip MEMS XO, 100 MHz, CMOS","metaDescription":"DSC1121AL5-100.0000: Active XO (Standard) from Microchip, 100 MHz CMOS output, ±10 ppm stability, -40°C to 105°C.
