DESCRIPTION
The DS90UR908Q converts FPD-Link II to FPD Link.
It translates a high-speed serialized interface with an
embedded clock over a single pair (FPD-Link II) to
four LVDS data/control streams and one LVDS clock
pair (FPD-Link). 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 decoding is used to support AC-coupled
interconnects.
The DS90UR908Q converter recovers the data
(RGB) and control signals and extracts the clock from
a serial stream (FPD-Link II). It is able to lock to the
incoming data stream without the use of a training
sequence or special SYNC patterns and does not
require a reference clock. A link status (LOCK) output
signal is provided.
Adjustable input equalization of the serial input
stream provides compensation for transmission
medium losses of the cable and reduces the medium-
induced deterministic jitter. EMI is minimized by the
use of low voltage differential signaling, output
voltage level select feature, and additional output
spread spectrum generation.
With fewer wires to the physical interface of the
display, FPD-Link output with LVDS technology is
ideal for high speed, low power and low EMI data
transfer.
The DS90UR908Q is offered in a 48-pin WQFN
package and is specified over the automotive AEC-
Q100 grade 2 temperature range of -40˚C to +105˚C.
