Various system use cases require multiple sensor devices with the same fixed I2C target address to be remotely accessible from the same I2C bus at the deserialilzer. The DS90UB954-Q1 provides target ID virtual addressing to differentiate target target addresses when connecting two or more remote devices. Eight pairs of TargetAlias and TargetID registers are allocated for each FPD-Link III Receive port in registers 0x5C through 0x6C. The TargetAlias register allows programming a virtual address which the host controller uses to access the remote device. The TargetID register provides the actual target address for the device on the remote I2C bus. Since eight pairs of registers are available for each port (total of 16 pairs), multiple devices may be directly accessible remotely without need for reprogramming. Multiple TargetAlias can be assigned to the same TargetID as well.
