7.3.14.1 Repeater Configuration

In the repeater application, this document refers to the DS90UB947-Q1 Serializer or as the Transmitter (TX), and refers to the DS90UB948-Q1 as the Receiver (RX). Figure 24 shows the maximum configuration supported for Repeater implementations. Two levels of Repeaters are supported with a maximum of three Transmitters per Receiver.

DS90UB947-Q1 30193310.gifFigure 24. 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.
