What this MEMS oscillator delivers for your clock tree
The DSC1101DE2-024.5760 is a standard XO (Standard) MEMS oscillator from Microchip's DSC1101 series, delivering a 24.576 MHz CMOS output with ±25 ppm absolute pull range. Its MEMS base resonator gives it an edge over quartz in shock resistance and startup time — useful if your board sees vibration or needs the clock stable within a few milliseconds of power-on.
Operating from 2.25V to 3.6V, this oscillator spans the 2.5V and 3.3V logic rails common in MCU and FPGA designs — no extra regulator needed if your rail is within that window. Rated for -20°C to 70°C, it covers commercial and most indoor industrial environments; the 35 mA max supply current is typical for a 24.576 MHz CMOS output at this voltage range.
Package and board layout — 6-VDFN footprint
Housed in a 6-VDFN package measuring 2.50mm x 2.00mm with a seated height of 0.90mm max, it fits tight PCB real estate — the 0.50 mm pitch pads need a clean solder mask defined pad and a via-in-pad if you route the supply on an inner layer.
