Note 1: GORB tied to Vcc or floating : Binary output data format. GORB tied to GND : Gray output data format
Note2: The common mode level of the output buffers is 1.2V below the positive digital supply.
For ECL compatibility the positive digital supply must be set at 0V (ground).
For LVDS compatibility (output common mode at +1.2V) the positive digital supply must be set at 2.4V.
If the subsequent LVDS circuitry can withstand a lower level for input common mode, it is recommended to lower the positive digital
supply level in the name proportion in order to spare power dissipation.
