Pin Description
(CBGA68 package)
Note:
1. 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 the input common mode, it is recommended to lower the
positive digital supply level in the same proportion in order to spare power dissipation
