2.3.2.1. Clock and Reset Interface Signals

Table 15.  Clock and Reset Interface Signals
Signal Name Direction Width Description
ref_clk Input 1 Reference clock for the PLL. The reference clock must be synchronous with group_strobe_in to ensure the dqs_enable signal is in-sync with group_strobe_in.
reset_n Input 1 Resets the interface. This is only for power-up reset. Reset of the PHY can only be achieved by enabling dynamic reconfiguration and writing to the TrainReset bit.
interface_locked Output 1 The interface_locked signal from PHY Lite for Parallel Interfaces Intel Agilex® 7 FPGA IP to the core logic. This signal indicates that the PLL and PHY circuitry are locked.

Data transfer should starts after the assertion of this signal.

rzq Input 1 This pin is visible if an I/O standard with on-chip termination (OCT) is selected in the IP parameter editor.
core_clk_out Output 1 Use this core clock in the core-to-periphery transfer of soft logic data and control signals.

The core_clk_out frequency depends on the interface frequency and clock rate of user logic parameter.
