5 - 65 MHz 24-bit Color FPD-Link to FPD-Link II Converter
General Description
The DS90UR907Q converts FPD-Link to FPD-Link II. It trans-
lates 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, re-
duces 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 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-em-
phasis 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 LLP package and is specified
over the automotive AEC-Q100 Grade 2 temperature range
of -40˚C to +105˚C.
