        LDQ10_and_lpGBT_I2C_issue-EDMS3398222_V1.pdf

        Dear lpGBT users,

        A functional issue has been discovered in the I2C slave implementation in the LDQ10 laser driver ASIC that is part of the VTRx+ module.
        Under a specific I2C bus conditions that my occur during system reset, the LDQ10 can enter an invalid internal state in which it fails to acknowledge I2C transactions.
        This issue has been investigated and a mitigation strategy has been elaborated, as detailed in this EDMS document: https://edms.cern.ch/document/3398222/1.
        Please let us know if you have any further questions or comments.

        Best regards,
        Szymon Kulis / Jan Troska
