The DSC6003HI2B-745K000T is an active-production XO (Standard) MEMS oscillator from Microchip's DSC60XXB series, qualified to AEC-Q100 for automotive applications. It delivers a 745 kHz CMOS output with ±25 ppm frequency stability across the -40°C to +85°C industrial temperature range — suitable for under-hood or cabin electronics where quartz alternatives may drift or fail under vibration.
Supply voltage flexibility and package footprint
Operates from a single 1.8V to 3.3V supply rail, covering common automotive logic levels without an external regulator. Housed in a 4-VFLGA package measuring 1.60 mm x 1.20 mm with a seated height of 0.89 mm — the small footprint suits space-constrained ECU or sensor module layouts, though the LGA land pattern requires careful solder-paste stencil design to avoid bridging.
