MEMS oscillator replaces quartz — what changes
The DSC1001DE2-026.0000T is a MEMS-based XO (Standard) producing a 26 MHz CMOS output, not a quartz crystal — the MEMS resonator is the timing element, so there is no load-capacitance matching to worry about, and the part is more resistant to shock and vibration than a quartz can.
AEC-Q100 qualification and automotive fit
Rated AEC-Q100, this oscillator is qualified for automotive-grade stress and reliability — suitable for cabin or chassis-domain modules that need a 26 MHz reference for an MCU or CAN controller, provided the -20°C to 70°C ambient range matches the module's thermal profile.
Operates from 1.8V to 3.3V on a single supply — one part number serves designs that run at 1.8V, 2.5V, or 3.3V, simplifying BOM consolidation across multiple voltage domains. Maximum supply current is 6.3 mA at 26 MHz, which is typical for a MEMS oscillator at this frequency — the CMOS output swings rail-to-rail, so the load capacitance on the output trace adds to the dynamic current draw.
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm max — the small footprint suits space-constrained PCBs, but the no-lead construction means the solder pads are under the body, so the PCB land pattern must match the recommended footprint for proper fillet formation.
