4.2. IP Port List
The following table lists the ports for the IP; all ports are 1-bit wide.
Port Name | Direction | Description |
---|---|---|
i_refclk | Input | Reference clock input port. Must be assigned to device reference clock pin. This port can be connected to the local or regional reference clock pins, or the reference clock pins from the HVIO bank, described in the System PLL with HVIO Reference Clock section. Refer to the device pinout documentation for the available pins. If this port connects to differential pins, you must connect the positive signal of the differential pair to this input port. |
i_refclk_ready | Input | Reference clock ready indicator port. This port is available only when user selects a non- PCIe* mode. Refer to the PCIe* IP user guide for more information about the PCIe* mode. This port indicates when the reference clock becomes available for the first time. |
o_pll_lock | Output | System PLL lock output port. System PLL lock status port which indicates if system PLL is locked to incoming reference clock. |
o_syspll_c0 | Output | System PLL clock output c0 port. This must be connected to system PLL clock input of protocol IP. |
