The 2.25V to 3.6V supply range means this oscillator runs directly from a 2.5V or 3.3V rail without an external regulator — a clean fit for mixed-voltage digital cores and FPGA clock trees.
Housed in a 6-VDFN package with an exposed pad (7.00 mm x 5.00 mm, 0.90 mm seated height), the thermal pad should be soldered to a ground-plane copper pour for heat sinking and mechanical stability.
The output frequency is 53.125 MHz, specified as a CMOS-level clock signal.
It operates from a 2.25V to 3.6V supply, so it is compatible with both 2.5V and 3.3V CMOS logic rails without a level translator.
Yes, it includes an Enable/Disable pin. When disabled, the maximum supply current drops from 35 mA to 22 mA.
