The DSC1001CE1-004.8500T is a 4.85 MHz XO (Standard) oscillator built on a MEMS resonator, delivering CMOS output with ±50 ppm frequency stability across its -20°C to 70°C operating range. AEC-Q100 rated — this part meets the stress and reliability qualification for automotive ICs, though the commercial temperature grade limits its ambient to cabin or climate-controlled zones, not under-hood. Supply voltage spans 1.7V to 3.6V, covering 1.8V, 2.5V, and 3.3V logic rails without an external regulator.
MEMS resonator and standby function
Maximum active supply current is 8 mA at 4.85 MHz, keeping the thermal footprint low in the 4-VDFN package.
Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint for space-constrained automotive ECU or sensor modules. Surface-mount assembly; the 4-pin VDFN layout requires standard reflow profiling with no special via-in-pad or thermal pad considerations.
