The DSC1001DI1-026.0000 is a 26 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output from a 1.8V to 3.3V supply rail. The MEMS base resonator replaces a quartz crystal — no load-capacitance matching needed, and the part resists the shock and temperature cycling that can crack a quartz blank.
Operating from 1.8V to 3.3V, this single oscillator covers both low-voltage SoC cores and 3.3V peripheral buses — one BOM line serves multiple voltage domains. Active current draw is 6.3 mA max at 26 MHz — low enough that a 3.3V LDO feeding the oscillator does not need a heatsink or wide PCB trace.
Product status is Active — no last-time-buy notice, no imminent EOL. Procurement can commit to this BOM line without a forced redesign window.
