Runs from any rail between 2.25V and 3.6V, so a single 2.5V or 3.3V supply is sufficient—no extra LDO needed.
The 5.00mm x 3.20mm 20-VFQFN with exposed pad (0.90mm height) requires a thermal pad on the PCB for heat sinking. The 0.50mm pitch pads demand careful fan-out on a 4-layer board; two-layer designs can break out the outer rows but may struggle with signal integrity at 100 MHz.
±25 ppm across the full -20 to 70°C operating range. That is tight enough for 1000BASE-T Ethernet and most FPGA reference clocks without external VCXO or temperature compensation.
Yes, the function is Enable/Disable. Pulling the pin low tri-states the outputs, which helps with power sequencing or test isolation.
