Supply voltage spans 1.8V to 3.3V, letting the same oscillator feed a 1.8V FPGA bank or a 3.3V PHY without a level translator. ## AEC-Q100 qualification and package footprint The 4-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight board stacks in engine control units, ADAS modules, or infotainment head units. For a 66.6666 MHz clock driving a gigabit PHY reference, the MEMS construction holds the ppm budget over the product lifetime without recalibration.
