- | The Cora Z7 provides a 50 MHz clock to the Zynq PS_CLK input, which is used to generate the clocks for each of the Processing System (PS) subsystems. The 50 MHz input allows the processor to operate at a maximum frequency of 650 MHz and the DDR3 memory controller to operate at a maximum of 525 MHz (1050 Mbps).
