WebJun 24, 2013 · PLL and clock details are specific to the processor / SoC in question. Block diagrams would show clock tree of SoC input pins leading to various PLLs, then various clocks driven from each PLL (may also have power domains that can be turned on/off), and clocks individually enabled once the "prepare" is done. WebThe displayport protocol runs at a fixed frequency of either 1.62GHz, 2.7GHz, or 5.4GHz. The pixel stream (strm_clk) it carries runs at an arbitrary frequency and is likely to be asynchronous to the link clock (link_clk). The receiver is supposed to recover strm_clk from two numbers M,N, as their ratio, i.e., strm_clk/link_clk = M/N, where N is ...
