66.6666 MHz MEMS XO — industrial temperature grade
Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without an external regulator — the 35 mA max draw is the peak during active output, dropping to 95 µA in standby (power-down) via the function pin.
6-SMD no-lead package — layout fit
The 5.00 mm x 3.20 mm body, 0.90 mm seated height, in a 6-SMD no-lead package — the land pattern matches standard 5x3.2 mm MEMS oscillator footprints from other vendors, so the BOM position swaps without a PCB spin.
