DS90UB925Q
5 - 85 MHz 24-bit Color FPD-Link III Serializer with Bidirectional Control
Channel
General Description
Features
The DS90UB925Q serializer, in conjunction with the
DS90UB926Q deserializer, provides a complete digital inter-
face for concurrent transmission of high-speed video, audio,
and control data for automotive display and image sensing
applications.
Bidirectional control interface channel interface with I2C
●
compatible serial control bus
Supports high definition (720p) digital video format
●

●
RGB888 + VS, HS, DE and I2S audio supported
Supports two 10–bit camera video streams
The chipset is ideally suited for automotive video-display sys-
tems with HD formats and automotive vision systems with
megapixel resolutions. The DS90UB925Q incorporates an
embedded bidirectional control channel and low latency GPIO
controls. This chipset translates a parallel interface into a sin-
gle pair high-speed serialized interface. The serial bus
scheme, FPD-Link III, supports full duplex of high-speed video
data transmission and bidirectional control communication
over a single differential link. Consolidation of video data and
control over a single differential pair reduces the interconnect
size and weight, while also eliminating skew issues and sim-
plifying system design.
5 – 85MHz PCLK supported
Single 3.3V Operation with 1.8V or 3.3V compatible
LVCMOS I/O interface
●
AC-coupled STP Interconnect up to 10 meters

Parallel LVCMOS video inputs
DC-balanced & scrambled Data w/ Embedded Clock
Supports repeater application
Internal pattern generation
Low power modes minimize power dissipation
Automotive grade product: AEC-Q100 Grade 2 qualified
The DS90UB925Q serializer embeds the clock, DC scram-
bles & balances the data payload, and level shifts the signals
to high-speed low voltage differential signaling. Up to 24 data
bits are serialized along the video control signals.
>8kV HBM and ISO 10605 ESD rating
Backward compatible to FPD-Link II
●
Applications
Serial transmission is optimized by a user selectable de-em-
phasis. EMI is minimized by the use of low voltage differential
signaling, data scrambling and randomization and spread
spectrum clocking compatibility.
