Description
Yes, you must connect all Stratix® II GX transceiver power pins, regardless of transceiver functionality. You do not need to make separate power planes for these VCCH pins. Since these power pins will not be supporting any dynamic currents, power plane decoupling capacitors are not necessary.
In order to save the recommended separate power supply for VCCH, you can tie VCCH pins to VCCR (1.2V) power supply.
