Wire-bond packages only support up to 624 Mbps until characterization shows otherwise.
See
There is a multiplexer here to select the PLL clock source. If a PLL uses this multiplexer to clock channels outside of
its bank quadrant (e.g., if PLL 2 clocks PLL 1’s channel region), those clocked channels support up to 840 Mbps.

Fast PLL SERDES Channel Support
The Quartus II MegaWizard Plug-In Manager only allows you to
implement up to 20 receiver or 20 transmitter channels for each fast PLL.
These channels operate at up to 840 Mbps. For more information on
implementing more than 20 channels, see
receiver and transmitter channels are interleaved such that each I/O bank
on the left and right side of the device has one receiver channel and one
transmitter channel per row.
