2.3.3.1. Quartus II Software-Selected Receiver Datapath Interface Clock

Quartus II software automatically picks the appropriate clock from the FPGA fabric to clock the receiver datapath interface.
Figure 78. 6-Gbps Receiver Datapath Interface Clocking for Non-Bonded ChannelsThe figure shows receiver datapath interface of two 6-Gbps transceiver non-bonded channels clocked by their respective receiver PCS clocks, which are forwarded to the FPGA fabric.


Figure 79. Arria V GT/ST 10-Gbps Receiver Datapath Interface Clocking for Non-Bonded ChannelsThe figure shows Arria V GT/ST receiver datapath interface of two 10-Gbps transceiver non-bonded channels clocked by their respective receiver CDR recovered PMA clocks, which are forwarded to the FPGA fabric.


Figure 80. 6-Gbps Receiver Datapath Interface Clocking for Three Bonded ChannelsThe figure shows the 6-Gbps receiver datapath interface of three bonded channels clocked by the rx_clkout[0] clock. The rx_clkout[0] clock is derived from the central clock divider of channel 1 or 4 in a transceiver bank.
