Supply voltage spans 2.25V to 3.63V, so the same BOM line works with a 2.5V or 3.3V rail without a separate regulator.
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard footprint that matches many quartz oscillator pads, simplifying a drop-in swap.
It outputs LVDS (Low-Voltage Differential Signaling), a differential signal standard that provides good noise immunity for routing the 40 MHz clock across a PCB.
The 7.00 mm x 5.00 mm 6-SMD footprint matches many quartz oscillator packages, and the LVDS output is common for high-speed clocks, so a direct replacement is possible if the board's supply and enable logic are compatible.
