4.2.1. Avalon System Clock

The Avalon system clock, sys_clk, is an input to the RapidIO II IP core that drives the Transport and Logical layer modules and most of the Physical layer module.
Note: You must drive the sys_clk clock from the same source from which you drive the tx_pll_refclk input clock.
