The receiver PLLs and CRUs are capable of supporting up to 3.1875 Gbps.
The input clock frequency for –5 and –6 speed grade devices is limited to
650 MHz if you use the REFCLKB pin or 325 MHz if you use the other
clock routing resources. The maximum input clock frequency for –7 speed
grade devices is 312.5 MHz if you use the REFCLKB pin or 156.25 MHz
with the other clock routing resources. An optional RX_LOCKED port
(active low signal) is available to indicate whether the PLL is locked to the
reference clock. The receiver PLL has a programmable loop bandwidth,
which can be set to low, medium, or high. The loop bandwidth parameter
can be statically set by the Quartus II software.

the parameters listed are statically programmable in the Quartus II
software.
