    Hi Banupriya,

    Thanks for reaching out. I have reviewed U133 in the schematics and have following inputs:

    1. Supply Decoupling Capacitors are not as required on VIO, VDD , VISOUT and VISOIN pins. The Datasheet has all the necessary details 
      1. Refer Section 11.2, Figure 11-1 for Schematics with required decaps values.
      2. Refer Section 13.2 for layout guidelines for future layout 

    Regards
    Varun
