Clocking/Interface Options
The following describes the Clocking/Interface options available in Cyclone IV GX
devices. The core clocking setup describes the transceiver core clocks that are the
write and read clocks of the Transmit Phase Compensation FIFO and the Receive
Phase Compensation FIFO, respectively. Core clocking is classified as transmitter core
clocking and receiver core clocking.
The following are the input control signals:
