JESD204b -- How Many Device Clocks

I am specifying an FPGA module that implements an JESD204b interface with an Arria 10 device.  I have 4 each ADC devices that have 2 serial data lanes each (16 lanes total).   The transceiver blocks on the FPGA come 6 per block.  The puzzle is:

1.  How many transceiver blocks will I need to use ?

2.  Will I need to run an individual JESD204b Device Clock from the device-clock/sysref management circuit to every blocks clock reference pin or can one device clock be distributed  on the "xN" internal Arria 10 clock network ( or some other method)?

3.  Maximum Serializer/Deserializer frequency is expected to be below 6 Gbps.
