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 mediuminduced

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 AECQ100

grade 2 temperature range of -40˚C to +105˚C.
