The DSC1001DI2-125.0000T is a 125 MHz MEMS-based XO with CMOS output, rated over -40 to 85°C with ±25 ppm frequency stability. Supply voltage spans 1.8V to 3.3V, so the same BOM line works across a 3.3V main rail or a 1.8V I/O bank without a level translator.
Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm max. The 0.098" x 0.079" footprint matches the standard 2.5 x 2.0 mm MEMS oscillator land pattern — no via-in-pad needed, but the four pads (VDD, GND, OUT, OE/STANDBY) should be routed with short traces to keep the 125 MHz edge clean.
