The DSC1101DE2-100.0000T is a 100 MHz MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a CMOS output from a 2.25V to 3.6V supply rail. The absolute pull range (APR) is ±25 ppm, which defines the tuning range available for frequency adjustment — relevant if this oscillator feeds a PLL that needs to absorb crystal aging or temperature drift.
Package, footprint, and rework considerations
Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this is a compact surface-mount oscillator that reflows with a standard lead-free profile. Orientation is marked by a pin-1 chamfer on the package corner — a quick visual check before hot air avoids a 180° placement error that shorts supply to ground.
