arriaII GX Transceiver (SDI)

I'm planning to use EP2AGX65.EP2AGX65 has 8 Transceiver channel(use for SDI).
Channel names(pin name) are from GXB_x0x to GXB_x7x(X=p,n).Banks are QL0 and QL1
Refclk names(pin name) are REFCLK0x,REFCLK1x,REFCLK4x and REFCLK5x.
I think 2 Transceiver bloks(GXB) is here.
First block include GXB_x0x to GXB_x3x.
Second block include GXB_x4x to GXB_x7x.
But I don't understand allocation of REFCLK well.
First block include REFCLK0,1.
Second block include REFCLK4,5.
Is it right?
I want to use SDI refclk 148.5MHz and 148.35MHz.
And I assign 148.35MHz to refclk0.
I assign 148.5MHz to refclk1.
Can the respective transceivers(8 channels) use refclk0 or refclk1?
Can 1 transceiver choose refclk0 or refclk1?
