16 MHz MEMS XO with full military temperature range
The DSC1101DM2-016.0000T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1101 series, delivering a 16 MHz CMOS output with ±25 ppm frequency stability across the full -55°C to 125°C military temperature range. That temperature grade — -55°C to 125°C — is the key differentiator here. Most standard crystal oscillators top out at 85°C or 105°C; this part keeps running in avionics, downhole instrumentation, satellite payloads, or engine-bay electronics where the ambient hits 125°C and the board itself is the heat sink.
The supply range spans 2.25V to 3.6V, covering 2.5V and 3.3V logic rails without an external regulator. Maximum active current is 35 mA at 16 MHz, typical for a MEMS oscillator driving a CMOS load.
6-VDFN package and board-fit note
Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — the 0.098" x 0.079" footprint saves board area compared to a standard 5x7 mm or 3.2x2.5 mm quartz oscillator. The surface-mount package reflows with standard lead-free profiles.
