Other important features of the Stratix GX transceivers are the power
down and reset capabilities, the external voltage reference and bias
circuitry, and hot swapping.
Individual Power-Down & Reset for the Transmitter & Receiver
Stratix GX transceivers offer a power saving advantage with their ability
to shut off functions that are not needed. The device can individually
reset the receiver and transmitter blocks and the PLLs. The Stratix GX
device can either globally power down and reset the transmitter and
receiver channels or do each channel separately.
