MEMS oscillator for 44 MHz CMOS clock trees
The DSC1001CI5-044.0000 is a 44 MHz XO (Standard) built on a MEMS resonator with CMOS output — it replaces a quartz crystal plus load caps with a single 4-SMD no-lead package that starts up without external tuning.

Package footprint and board layout
The 3.20 mm × 2.50 mm body with a 0.90 mm seated height fits the compact 4-SMD no-lead footprint — standard for 2.5 × 3.2 mm oscillators — and the surface-mount termination allows reflow soldering without through-hole clearance on the opposite side.
