Automotive-grade MEMS timing
This is a MEMS-based XO (Standard) from the DSC1001 series, delivering a 4 MHz CMOS output with ±20 ppm frequency stability across its full -40°C to 85°C range. The AEC-Q100 rating confirms qualification for automotive applications — the part is tested to the temperature, reliability, and PPAP requirements expected in under-hood or cabin electronics. The 1.7V to 3.6V supply range covers 1.8V, 2.5V, and 3.3V logic rails, so a single oscillator can serve multiple voltage domains on the board without an external regulator.
Standby power and package footprint
Active current is 8 mA max at 4 MHz. The 4-VDFN package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits dense automotive ECU layouts.
