3 Description
The DS90UR907Q-Q1 converts FPD-Link to FPD-
Link II. It translates four LVDS data/control streams
and one LVDS clock pair (FPD-Link) into a high-
speed serialized interface (FPD-Link II) over a single
pair. This serial bus scheme greatly eases system
design by eliminating skew problems between clock
and data, reduces the number of connector pins,
reduces the interconnect size, weight, and cost, and
overall eases PCB layout. In addition, internal DC
balanced encoding is used to support AC-coupled
interconnects.
The DS90UR907Q-Q1 converts, balances and level
shifts four LVDS data/control streams, and embeds
one LVDS clock pair (FPD-Link) to a serial stream
(FPD-Link II). Up to 24 bits of RGB in the FPD-Link
are serialized along with the three video control
signals.
Serial transmission is optimized by a user selectable
de-emphasis and differential output level select
features. EMI is minimized by the use of low voltage
differential signaling and spread spectrum clocking
compatibility.
With fewer wires to the physical interface of the host,
FPD-Link input with LVDS technology is ideal for high
speed, low power and low EMI data transfer.
The device is offered in a 36-pin WQFN package and
is specified over the automotive AEC-Q100 Grade 2
temperature range of –40˚C to 105˚C.
