1. In PLL Bypass mode (PLL_BYPASS = HIGH), output will support frequencies down to 0Hz (divider chain is a fully static design).
2. See Figures 6 and 7 for output loads.
3. Input and outputs LVCMOS mode
4. Inserted feedback loop delay < 7ns
5. Measured with fOUT = 100MHz, fVCO = 400MHz, input and output interface set to LVCMOS.
