The DS90UB91xQ-Q1 2:1 Multiplexer to Choose Between Two Input chipsets incorporate differential signaling on both the Imagers high-speed forward channel and bidirectional control Embedded Clock With DC-Balanced Coding to channel data paths. The serializer and deserializer Support AC-Coupled Interconnects pair is targeted for connections between imagers and Capable of Driving up to 25 Meters Shielded video processors in an electronic control unit (ECU). Twisted-Pair This chipset is ideally suited for driving video data that requires up to 12-bit pixel depth plus two Receive Equalizer Automatically Adapts for synchronization signals along with bidirectional Changes in Cable Loss control channel bus. Four Dedicated General-Purpose Input/Output There is a multiplexer at the deserializer to choose Pins (GPIO) Available on Both Serializer and between two input imagers. The deserializer can Deserializer have only one active input imager. The primary video LOCK Output Reporting Pin and AT-SPEED BIST transport converts 10- and 12-bit data over a single Diagnosis Feature to Validate Link Integrity high-speed serial stream, along with a separate low 1.8-V, 2.8-V or 3.3-V Compatible Parallel Inputs latency bidirectional control channel transport that 2 accepts control information from an I C port and is on Serializer independent of video blanking period.
