The DSC1001BL2-027.0000T is a 27 MHz MEMS-based XO (Standard) with CMOS output, rated across -40°C to 105°C — the full industrial-plus-automotive temperature band. Supply voltage spans 1.8 V to 3.3 V, so a single BOM line covers 1.8 V-core MCUs and 3.3 V-peripheral rails without a separate level translator on the clock tree. Frequency stability is ±25 ppm — tight enough for CAN FD, Ethernet, and USB full-speed clocking without external trimming.
Housed in a 4-SMD, No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm — the same footprint as standard quartz oscillators, so a board designed for a quartz XO accepts this MEMS part without layout changes.
