Figure 31. Maximum Repeater Application
In a repeater application, the I²C interface at each TX and RX is configured to transparently pass I²C
communications upstream or downstream to any I²C device within the system. This includes a mechanism for
assigning alternate IDs (Slave Aliases) to downstream devices in the case of duplicate addresses.
