Zynq - What is the maximum QSPI frequency for (x1,x2,x4,x8) modes?

描述

What is the maximum QSPI (xX) mode frequency?

解决方案

With the feedback clock enabled, the maximum QSPI device frequency is theoretically 100MHz since the max PCAP (processor configuration access port) frequency is rated at 100MHz. This speed might be limited in practice by the configuration speed the flash allows for and the LVCMOS IOstandard used for the configuration lines.
