Active MEMS oscillator for multi-voltage clock trees
The DSC1101DC1-025.0000T is an active-production MEMS-based XO from Microchip's DSC1101 series, delivering a 25 MHz CMOS output with ±50 ppm frequency stability across the full 2.25V to 3.6V supply range. The 6-VDFN package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm, fitting tight board profiles in portable or space-constrained assemblies.
Standby mode for battery-life extension
This lets a microcontroller or PMIC gate the oscillator without an external load switch — the enable pin directly controls the clock tree's idle power.
Supply voltage flexibility and design margin
The 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails with margin, so the same BOM line serves mixed-voltage designs without a separate regulator. At 3.3V nominal, the part is well within its operating envelope; no derating needed for the upper end of the supply range.
