Using a quartz oscillator here means you carry the risk of quartz supply allocation and longer start-up time—the MEMS resonator in this DSC1104BI2-100.0000 eliminates that exposure while delivering the same ±25 ppm stability across -40°C to 85°C. The wide supply range (2.25V to 3.6V) lets you drop this onto either a 2.5V or 3.3V rail without a separate LDO—one less part to qualify. ## HCSL output and termination HCSL is a differential, open-emitter output requiring a pull-up to ground on each leg. The 100 MHz output drives the typical differential termination directly. ## MEMS vs quartz: sourcing reality MEMS oscillators have a shorter, more predictable lead time than quartz because the resonator is a semiconductor fab process, not a crystal blank—no quartz supply constraints. The 6-SMD, No Lead package (5.00mm x 3.20mm, 0.90mm seated height) is a standard footprint shared by many MEMS and quartz XOs; a board designed for a quartz 5.0x3.2mm oscillator will accept this part without layout changes.","metaTitle":"DSC1104BI2-100.0000 Microchip 100 MHz MEMS XO HCSL - Active","metaDescription":"Active Microchip DSC1104BI2-100.0000: 100 MHz MEMS XO, HCSL output, ±25 ppm, -40°C to 85°C, 2.25V-3.6V supply.
