基于DS90UB941AS-Q1和DS90UB948-Q1的高可靠车载视屏传输方案设计要点

Figure 1.  Design Can the Deser device support hot plug by STP (COAX) cable ?
If there is a need to reduce system power consumption, can the Deser device wake up through its interrupt when the Ser side enters power-down mode?

    Hi,

    Hot plugging 941 FPD link is not recommended.

    If hot plug is required, the DES AEQ should be reset after each hot plug to ensure the AEQ is locking to the correct signal coming from 941AS.

     When the SER side is in power-down mode, the SER device cannot transfer any signal, including interrupts, to the DES side.

    BR,
