Clock	Description
s_axi_aclk	The AXI clock is used for table management. The AXI management interface has a completely asynchronous relationship with the lookup interface.
key_clk	AXI4-Stream clock for Lookup Request/Response interfaces.
ram_clk	The ram_clk is optional. It provides an option to clock the internal RAM and match logic on a separate high frequency clock. In most cases this saves logic and memory resources. Guideline: key_clk <= 300 MHz, use ram_clk up to 600 MHz key_clk > 300 MHz, ram_clk is not used
