MEMS oscillator for automotive clock trees
The DSC6001JI2B-024.0000 is a 24 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC60XXB series, qualified to AEC-Q100 for automotive applications. The MEMS resonator is inherently more resistant to shock and vibration than a quartz crystal, making it a fit for under-hood and chassis-mounted ECUs where mechanical stress is a concern. Output is CMOS, which directly drives the clock input of most MCUs, FPGAs, and SoCs without external level translation. The Enable/Disable function lets the output be tri-stated for power gating or clock muxing, saving a buffer or FET on the BOM. Supply voltage spans 1.71V to 3.63V, covering both 1.8V and 3.3V logic rails from a single part — useful in mixed-voltage designs where a single oscillator must feed multiple domains.
AEC-Q100 qualification and temperature grade
Rated AEC-Q100, the DSC6001JI2B-024.0000 is qualified for automotive-grade reliability stress and temperature cycling. Sourced through independent distribution — quoted to order against the BOM quantity.
Package and board-level fit
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm. The small footprint saves board space compared to a quartz oscillator in a 5x3.2 mm or larger package. Frequency stability is ±25 ppm over the full temperature range, which is tight enough for USB full-speed (12 Mbps) and CAN bus without external trimming. Typical supply current is 1.3 mA at 24 MHz — low enough for battery-backed real-time clock references in automotive body controllers.
