NOTES:
1. For all LVCMOS compatible inputs.
2. For LVCMOS compatible output SE_CLK.
3. For LVCMOS compatible output LOCK.
4. While still satisfying V_OL max and V_OH min.
5. IO_VDD refers to the power supply that supplies the particular pin in question. D_VDD supplies pins 10-21. IN_VDD supplies CLKIN_SE.
SE_VDD supplies CLKOUT_SE.
