1.2.6. Clocking Scheme

The main reference clock for the design example is device_clk. This clock must be supplied from an external source. The device_clk is the reference clock for the core PLL, ATX PLL and the TX/RX transceiver PHY. The core PLL generates the link_clk and frame_clk from device_clk. The link_clk clocks the JESD204B IP core link layer and link interface of the transport layer. The frame_clk clocks the transport layer, test pattern generator and checker modules, and any downstream modules. An external source supplies a clock called the mgmt_clk to clock the Avalon® memory-mapped interfaces of Platform Designer components.
