Operating from a 1.8V to 3.3V supply, this oscillator can be powered directly from a 1.8 V core rail or a 3.3 V I/O rail without an external regulator — a single BOM line covers both voltage domains. Active supply current is 7.2 mA max at 40 MHz — the CMOS output swings rail-to-rail, so the load capacitance at the receiver pin sets the actual dynamic current; the 7.2 mA figure assumes a standard 15 pF load.
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the footprint matches the industry-standard 3.2 x 2.5 mm oscillator land pattern — no board spin needed if you are migrating from a quartz XO in the same package.
