7.4.4 Repeater Application
The DS90UB925Q-Q1 and DS90UB926Q-Q1 can be configured to extend data transmission over multiple links
to multiple display devices. Setting the devices into repeater mode provides a mechanism for transmitting to all
receivers in the system.
In a repeater application, in this document, the DS90UB925Q-Q1 is referred to as the Transmitter or transmit port
(TX), and the DS90UB926Q-Q1 is referred to as the Receiver (RX). Figure 20 shows the maximum configuration
supported for Repeater implementations using the DS90UB925Q-Q1 (TX) and DS90UB926Q-Q1 (RX). Two
levels of Repeaters are supported with a maximum of three Transmitters per Receiver.
