We are using Arria 10 with 480K LEs in F34 package device which also has 12 fractional PLLs. Eight of these fPLLs are located in standard transceiver banks, but four fPLLs are located outside of any transceiver bank.
Is it possible to use the out-of-bank fractional PLLs for HSSI transmitter clocking? Is there any clock network capable of delivering the high speed clock across the side of the device? Is it possible to use xN clock network for this purpose (does it have sufficient span)?
