The DSC6003HI1B-745K000T is a MEMS-based XO (Standard) from Microchip's DSC60XXB series, delivering a 745 kHz CMOS output with ±50 ppm frequency stability across the full -40°C to +85°C range. AEC-Q100 qualification makes it suitable for automotive cabin and chassis-domain electronics where quartz oscillators may fail under shock or vibration — the MEMS resonator inherently withstands higher g-forces and offers faster startup. The 1.71V to 3.63V supply range lets it run directly off a 1.8V or 3.3V rail without a secondary LDO, simplifying the power tree in space-constrained designs.
Package, footprint, and board-level fit
Housed in a 4-VFLGA package measuring 1.60 mm × 1.20 mm with a seated height of 0.89 mm, the compact footprint suits miniaturized modules but demands a well-controlled solder-paste stencil and X-ray inspection to detect voiding under the exposed pad.
