MEMS oscillator for automotive clock trees
The DSC6001JA2B-025.0000T is a 25 MHz MEMS-based XO (Standard) from Microchip's DSC60XXB series, delivering a CMOS output across a 1.8V to 3.3V supply range. Rated for -40°C to 125°C and AEC-Q100 qualified, it fits directly into automotive Grade 1 applications — engine control units, transmission modules, and chassis-domain ECUs where quartz oscillators risk frequency shift under vibration. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal, which can exhibit start-up frequency errors under mechanical stress — a known failure mode in automotive and industrial environments.
Supply voltage and frequency stability
Operating from 1.8V to 3.3V, the oscillator can be powered from a single 1.8V or 3.3V rail without a level translator — a single BOM line serves both voltage domains. Frequency stability is ±25 ppm over the full temperature range and lifetime — tight enough for CAN, LIN, and USB full-speed interfaces without requiring a higher-grade ±10 ppm part. Typical supply current is 1.3 mA, lower than many quartz-based equivalents — relevant for battery-backed or always-on modules where every microamp matters.
Enable/Disable and package footprint
The enable/disable function lets the system power down the oscillator when the clock is not needed — reduces idle current in multi-rail designs or sleep-mode ECUs. Housed in a 4-VLGA package measuring 2.50mm x 2.00mm with a seated height of 0.89mm, the footprint is smaller than a typical 4-pin SMD crystal can, saving board space in densely packed automotive modules.
