The multipurpose PLLs and general-purpose PLLs located on the left side of the
device generate the clocks required for the transceiver operation. The following
sections describe the Cyclone IV GX transceiver clocking architecture:

When used for transceiver, the left PLLs synthesize the input reference clock to
generate the required clocks for the transceiver channels.
show the sources of input reference clocks for PLLs used in the transceiver operation.
Clock output from PLLs in the FPGA core cannot feed into PLLs used by the
transceiver as input reference clock.

Notes to
(1) The REFCLK0 and REFCLK1 pins are dual-purpose CLK, REFCLK, or DIFFCLK pins that reside in banks 3A and
(2) Using any clock input pins other than the designated REFCLK pins as shown here to drive the MPLLs may have
