8.3.14 Repeater
The supported Repeater application provides a mechanism to extend transmission over multiple links to multiple
display devices.
8.3.14.1 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 25 shows the maximum configuration supported for
Repeater implementations. Two levels of Repeaters are supported with a maximum of three Transmitters per
Receiver.
