DS90UB948-Q1: FPD-LINK abnomal data detects

Part Number: DS90UB948-Q1

Hello TI,

    We use DS90UB949 and DS90UB948 chips. 

   When the input signal of UB949 FPD-LINK is abnormal (for example, only FPD-LINK has a set of abnormal signals), can UB948 detect the abnormal signal?

    Hi Jinsheng, 

    The 949 to 948 link has a lock register/pin that verifies the deserializer's PLL is locking to the forward channel data/clock. Also, the Pass pin also identifies some faults or corrupt display timing/data on the link. Additionally there is also a link error counter (register 0x41) that monitors errors in some of the control/overhead bits.

    Regards,
