Figure 25. 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.

The Repeater requires the following connections between the Receiver and each Transmitter Figure 27.
1. Video Data – Connect all FPD-Link data and clock pairs. Single FPD-Link (D[3:0]) or Dual FPD-Link (D[7:0])
are both possible, provided the Deserializer and all Serializers are configured in the same mode.
