The DSC1123BL2-125.0000 is a 125 MHz MEMS-based XO with LVDS output, built for applications that need a clean differential clock across -40°C to 105°C — the full AEC-Q100 Grade 1 band. Supply voltage spans 2.25V to 3.63V, so it runs from a 2.5V or 3.3V rail without an external regulator, and the Enable/Disable pin lets the system gate the clock for power savings — the disabled supply current drops to 22 mA max from 32 mA max.

Package dimensions and layout note
The 6-SMD, No Lead package measures 5.00 mm × 3.20 mm with a seated height of 0.90 mm max — a standard 5.0×3.2 mm footprint shared by many MEMS and quartz oscillators, so a PCB already routed for that outline accepts this part without a layout change.
