  • [FAQ] DS90UB941AS-Q1: Access Two Deserializers in Splitter Mode which have the same I2C Address

    Part Number: DS90UB941AS-Q1 When DS90UB941AS-Q1 is connected to two remote deserializers in splitter or independent mode which have the same physical I2C address, how can they be accessed independently via I2C?

  • [FAQ] DS90UB962-Q1: Using Software to identify if deseralizer is 960 or 962

    Part Number: DS90UB962-Q1 Hi Team, I have a build that mixes 960s and 962s due to shortages. One of my cameras that connects to the build needs to dynamically reduce the FPS if it is connected to a 962 because the 3gbps link leads to bandwidth limitations…

  • [FAQ] DS90UB947-Q1: MAPSEL question

    Part Number: DS90UB947-Q1 Hi team My customer Hasco is using our 947 and configure its mode_sel1, here is our question: 1. When our VR6=0V, the 0x4F read back value is 0x40 which means the bit[7] is 0 and that is described to be the SPWG mapping…

  • [FAQ] DS90UB954-Q1: PDB Hard Reset Required?

    Part Number: DS90UB954-Q1 In the 954 datasheet the Power Up Sequencing figures 55 and 56 show a hard reset after the first PDB. Is this a requirement, recommendation, or only there to show if you do a hard reset after power up the required timing(t7…
