The DSC1003BE2-027.0000T is a 27 MHz MEMS-based XO (Standard) oscillator from Microchip Technology, delivering a CMOS output with ±25 ppm frequency stability across its -20°C to 70°C operating range. AEC-Q100 qualification means this part meets automotive-grade reliability testing — suitable for cabin electronics, infotainment clusters, or ADAS reference clocks where the ambient stays within the commercial temperature band.
Supply voltage and standby function
Housed in a 4-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — a standard footprint that matches many 5x3.2 mm oscillator pads. Surface-mount assembly with the 4-pad layout; no special via-in-pad or thermal relief required for this low-current device (7.4 mA max supply,).
