- CLK, CLKN
If unused, the clock signals should be biased to LVDS low or high for CLK and LVDS high or low for CLKN respectively. - LVDS Inputs (I0, I0N…I9, I9N, IOR, IORN, DAI, DAIN) If unused, the LVDS inputs should be biased to LVDS low for the positive signal of the pair and LVDS high for the negative signal of the pair. They can also be left open. - LVDS Outputs (A0, A0N…A9, A9N, AOR/DRAN, AORN/DRA, B0, B0N…B9, B9N, BOR/DRBN, BORN/DRB, C0, C0N…C9, C9N, COR/DRCN, CORN/DRC, D0, D0N…D9, D9N, DOR/DRDN, DORN/DRD, DR, DRN, DAO, DAON) The unused LVDS outputs can be left open. - DIODE If unused, the DIODE signal should be connected to ground. - DACTRL If unused, the DACTRL can be left open or connected to VCCD/2. - CLKDACTRL If unused, the CLKDACTRL should be connected to VCCD/2. |
