Supply voltage spans 2.25V to 3.6V, so the same part serves 2.5V and 3.3V logic rails without a separate regulator.
Housed in a 6-SMD no-lead package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Maximum current draw is 22 mA at full load, which keeps the thermal footprint low even in dense PCB layouts near sensitive analog or RF sections.
It is a standard XO (Standard) with CMOS output at 27 MHz.
