What this MEMS oscillator delivers for your clock tree
The supply range spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without an external regulator — a single DSC1121AE5-041.5000 can bridge a 2.5 V FPGA bank and a 3.3 V processor reference on the same board. Maximum supply current is 35 mA when enabled, and drops to 22 mA in the disabled state — the 13 mA difference is the output buffer draw, which is typical for a 41.5 MHz CMOS driver driving a 15 pF load.
The 6-VDFN exposed pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a low-profile, surface-mount footprint that reflows on a standard FR-4 board with a 0.50 mm pitch pad layout.
