DS90UB913Q/DS90UB914Q
PRODUCT BRIEF
10-100MHz 10/12-Bit FPD-Link III SER/DES
General Description
Features
The DS90UB913Q/DS90UB914Q 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 DS90UB913Q/914Q chipsets incorporate differential signaling on both the high-speed forward
channel and bidirectional control channel data paths. The Serializer/ Deserializer pair is targeted for connections between
imagers and video processors in an ECU (Electronic Control
Unit). This chipset is ideally suited for driving video data requiring up to 12 bit pixel depth plus two synchronization
signals along with bidirectional control channel bus.
There is a multiplexer at the Deserializer to choose between
two input imagers. The Deserializer can have only one active
input imager. The primary video transport converts 10/12 bit
data over a single high-speed serial stream, along with a separate low latency bidirectional control channel transport that
accepts control information from an I2C port and is independent of video blanking period.
Using TI’s embedded clock technology allows transparent fullduplex communication over a single differential pair, carrying
asymmetrical bidirectional control channel information in both
directions. 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 adaptive
equalization to compensate for loss from the media over
longer distances. Internal DC balanced encoding/decoding is
used to support AC-Coupled interconnects. The Serializer is
offered in a 32-pin LLP package and the Deserializer is offered in a 48-pin LLP package.
