The DSC1001BI1-100.0000 is a 100 MHz MEMS-based XO (Standard) with CMOS output, rated across -40°C to 85°C and ±50 ppm frequency stability. It is suited for under-hood and chassis-domain electronics where the ambient temperature can hit 85°C and the supply rail may vary from 1.8V to 3.3V.
The supply voltage range of 1.8V to 3.3V covers the three most common digital rails — 1.8V for low-power cores, 2.5V for I/O banks, and 3.3V for legacy logic. Maximum supply current is 8.7 mA — low enough for battery-powered modules.
The 4-SMD, No Lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The no-lead footprint has four castellations on the bottom — the two outer pads are supply and ground, the inner two are output and enable. The 0.50 mm pad pitch requires a standard 4-layer PCB stack-up for fan-out; a two-layer board can route the signals if the ground plane is continuous under the package.
