948 and 949 are used in the project. At present, the LOCK signal of 948 terminal is high, but there is no image out. After the LOCK becomes high, it can be explained that there is no problem with the hardware, is it all a problem of software configuration?

    948 and 949 are used in the project. At present, the LOCK signal of 948 terminal is high, but there is no image, which may be the reason for this. Can any register be detected at 948 terminal to help troubleshoot the problem?

    Hello,

    Has PATGEN been attempted from both the SER and DES side? Can the pattern be seen from the display? For more information regarding pattern generation from FPD-Link III IVI devices, please see the following app note: SNLA132.

    Can you also let me know what video timing parameters are being utilized?

    Best,

    Nikolas
