MEMS clock source for 100 MHz CMOS rails
The DSC1033CC2-100.0000T is a 100 MHz XO (Standard) from Microchip's PureSilicon™ MEMS oscillator family, delivering a CMOS output with ±25 ppm frequency stability across 0°C to 70°C. It runs on a 3.3V supply and draws 10 mA max from the rail — the MEMS resonator consumes less current than a comparable quartz crystal oscillator at the same frequency, which matters for power-constrained boards.
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3225 footprint that places cleanly without tombstoning risk. No MSL rating is listed on the evidence, but MEMS oscillators typically ship at MSL 1 — no bake required before reflow. Check the reel label to confirm before loading the feeder.
