1、理解mipi協(xié)議完成mipi信號通道分配后，需要生成勹物理層對接的時序、同步信號：MIPI規(guī)定,傳輸過程中，包內(nèi)是200mV、包間以及包啟動和包結(jié)束時是I.2V,兩種不同的電壓擺幅，需要兩組不同的LVDS驅(qū)動電路在輪流切換工作：為了傳輸過程中各數(shù)裾包之閬的安全可靠過渡，從啟動到數(shù)據(jù)開始傳輸，MIIP1定義了比較長的町雛過渡時間，加起來最少也存600多ns:而且規(guī)定各個時間參數(shù)足可調(diào)的，所以謠要一定等待時間，謠要綴存，我捫用寄存器代替FIFO,每通道128Byte。串行時鐘勺數(shù)據(jù)差分傳輸?shù)倪^渡時間關(guān)系如下：Figure2
