MEMS oscillator for extreme-temperature designs
Unlike quartz oscillators that typically top out at 85°C or 105°C, this MEMS resonator maintains ±25 ppm frequency stability from -55°C to 125°C — a fit for avionics, downhole instrumentation, satellite payloads, and engine-bay electronics where the ambient exceeds standard industrial limits.
The 2.25V to 3.6V supply range lets a single BOM line serve both 2.5V and 3.3V logic domains — no separate regulator or voltage translator needed for the clock rail.
Package, footprint, and tape-and-reel availability
Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2 x 2.5 mm footprint shared by many MEMS and quartz oscillators, simplifying second-source qualification.
The DSC1121 family is an established MEMS oscillator line from Microchip Technology, widely available through independent distribution. No stock-holding claim — sourced per request.
