Advance Information
+ 3.3 V + 5%. Power supply pair for the CLAD PLL circuitry.
+ 3.3 V + 5%. Power supply pairs for the digital circuitry.
To insure 5 V tolerance in mixed + 5 V / + 3.3 V systems, this input must
be connected to + 5 V. If all logic input signals are 3.3 V levels, then this
pin may be connected to the 3.3 V supply.
No-connect pins are reserved for future device compatibility and should
be left unconnected.
