Why choose a MEMS XO over a quartz crystal for this 4.096 MHz slot
For an ECU or sensor module that sees 105°C under-hood and 20 g vibration on the engine block, a quartz crystal can fracture or drift; the MEMS resonator keeps the 4.096 MHz output locked to ±20 ppm across the full -40°C to 105°C range.
That means it is still a valid design-in choice for new automotive or industrial builds, and the supply chain is stable through authorized channels.
Supply voltage flexibility and enable/disable function
The 1.71V to 3.63V supply range covers 1.8V, 2.5V, and 3.3V logic rails without an external level translator — useful when the same oscillator feeds a 3.3V MCU and a 1.8V CAN transceiver.
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm. Surface-mount reflow follows the JEDEC profile for the package; no moisture sensitivity level concern for standard MSL handling.
