DESCRIPTION
The DS90UB901Q/DS90UB902Q chipset offers a
FPD-Link III interface with a high-speed forward
channel and a bidirectional control channel for data
transmission over a single differential pair. The
Serializer/Deserializer pair is targeted for direct
connections between automotive camera systems
and Host Controller/Electronic Control Unit (ECU).
The primary transport sends 16 bits of image data
over a single high-speed serial stream together with a
low latency bidirectional control channel transport that
supports I²C. Included with the 16-bit payload is a
selectable data integrity option for CRC (Cyclic
Redundancy Check) to monitor transmission link
errors. Using TI’s embedded clock technology allows
transparent full-duplex communication over a single
differential pair, carrying asymmetrical bidirectional
control information without the dependency of video
blanking intervals. This single serial stream simplifies
transferring a wide data bus over PCB traces and
cable by eliminating the skew problems between
parallel data and clock paths. This significantly saves
system cost by narrowing data paths that in turn
reduce PCB layers, cable width, and connector size
and pins.
In addition, the Deserializer inputs provide
equalization control to compensate for loss from the
media over longer distances. Internal DC balanced
encoding/decoding is used to support AC-Coupled
interconnects.
A Serializer standby function provides a low power-
savings mode with a remote wake up capability for
signaling of a remote device.
The Serializer is offered in a 32-pin WQFN (5mm x
5mm) package, and Deserializer is offered in a 40-pin
WQFN (6mm x 6mm) package.
