Why choose a MEMS oscillator over quartz
The DSC1001DI2-064.0000 is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 64 MHz CMOS output with ±25 ppm frequency stability. Unlike quartz-based oscillators, MEMS resonators are inherently more resistant to vibration and shock, and they start up faster — no crystal startup margin to budget.
Automotive-grade timing for harsh environments
The 1.8V to 3.3V supply range means it can run directly from a 3.3V MCU rail or a 1.8V core supply without a level translator.
For new designs, this part is available to order; for existing BOM lines, the supply chain is stable through independent distribution.
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm. The 0.098" x 0.079" footprint is common for MEMS oscillators and matches standard 4-pin XO land patterns. Surface-mount assembly with no exposed paddle simplifies reflow profiling.
