1.5 Typical Application

The following diagram illustrates a typical rear seat entertainment application that utilizes the

DS90UB928Q deserializer and a compatible serializer (DS90UB925Q or DS90UB927Q). The

DS90UB928Q accepts FPD-Link III data transported over an automotive-grade STP cable and

deserializes the data stream into video, audio, and control information intended for a display and other

local peripherals.
