4.2.1.3. Other Input Clocks

In variations that target a device for which the transceivers are configured with the ALTGX megafunction, and not with a Transceiver PHY IP core, the transceiver's calibration-block clock is called cal_blk_clk.

In Arria® V, Cyclone® V, and Stratix® V devices, the transceiver has an additional clock, phy_mgmt_clk, which clocks the software interface to the transceiver. In Intel® Arria® 10 and Intel® Cyclone® 10 GX devices, the transceiver has an input clock bus tx_bonding_clocks_ch N. These clocks should be driven by the external TX transceiver PLL. Intel® Arria® 10 and Intel® Cyclone® 10 GX variations also have an option interface, the Intel® Arria® 10 and Intel® Cyclone® 10 GX Native PHY dynamic reconfiguration interface, which includes a clock signal for each transceiver channel.
