DS90UB926Q
5 - 85 MHz 24-bit Color FPD-Link III Deserializer with Bidirectional
Control Channel
General Description
Features
The DS90UB926Q deserializer, in conjunction with the
DS90UB925Q serializer, provides a complete digital interface
for concurrent transmission of high-speed video, audio, and
control data for automotive display and image sensing appli-
cations.
Bidirectional control interface channel interface with I2C
●
compatible serial control bus
Supports high definition (720p) digital video format
●
●
RGB888 + VS, HS, DE and synchronized I2S audio
supported
This chipset translates a parallel RGB Video Interface into a
single pair high-speed serialized interface. The serial bus
scheme, FPD-Link III, supports full duplex of high speed for-
ward data transmission and low speed backchannel commu-
nication over a single differential link. Consolidation of video
data and control over a single differential pair reduces the in-
terconnect size and weight, while also eliminating skew issues
and simplifying system design.
5 to 85 MHz 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 outputs
I2C compatible serial control bus for configuration
DC-balanced & scrambled Data w/ Embedded Clock
The DS90UB926Q deserializer recovers the RGB data, three
video control signals and four synchronized I2S audio signals.
It extracts the clock from a high speed serial stream. An output
LOCK pin provides the link status if the incoming data stream
is locked, without the use of a training sequence or special
SYNC patterns, as well as a reference clock.
Adaptive cable equalization
Supports repeater application
@ SPEED Link BIST Mode and LOCK status pin
Image Enhancement (White Balance and Dithering) and
Internal pattern generation
EMI Minimization (SSCG and EPTO)
The DS90UB926Q deserializer has a 31-bit parallel LVCMOS
output interface to accommodate the RGB, video control, and
audio data.

Low power modes minimize power dissipation
Automotive grade product: AEC-Q100 Grade 2 qualified
An adaptive equalizer optimizes the maximum cable reach.
EMI is minimized by output SSC generation (SSCG) and en-
hanced progressive turn-on (EPTO) features.
>8kV HBM and ISO 10605 ESD rating
Backward compatible to FPD-Link II
