It replaces quartz-based oscillators with a silicon MEMS resonator that resists vibration and shock better than a crystal — useful in engine-bay or chassis-mounted ECUs. AEC-Q100 qualification and a -40°C to +105°C operating range mean this part is rated for automotive temperature Grade 1 environments — under-hood, transmission control, or ADAS sensor modules where the ambient temp hits 105°C and the board sees 2000+ thermal cycles. The supply voltage spans 1.71V to 3.63V, so the same oscillator can clock a 1.8V MCU core, a 2.5V FPGA bank, or a 3.3V PHY without a separate LDO — one BOM line covers multiple rails.
Package, footprint, and board layout
Housed in a 4-VFLGA package measuring 2.00mm x 1.60mm with a seated height of 0.89mm, this oscillator fits tight PCB real estate.
The base product number is DSC6001; the suffix ML2B-040.0000 encodes the 40 MHz frequency, ±25 ppm stability, and the -40°C to +105°C temperature grade.
