DS99R124Q
5 - 43 MHz 18-bit Color FPD-Link II to FPD-Link Converter
General Description
Features
The DS99R124Q converts FPD-Link II to FPD-Link. It trans-
lates a high-speed serialized interface with an embedded
clock over a single pair (FPD-Link II) to three LVDS data/con-
trol 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 intercon-
nects.
5 – 43 MHz support (140 Mbps to 1.2 Gbps Serial Link)

4-channel (3 data + 1 clock) FPD-Link LVDS outputs
3 low-speed over-sampled LVCMOS outputs
AC Coupled STP Interconnect up to 10 meters in length
Integrated input termination
@ Speed link BIST mode and reporting pin
Optional I2C compatible Serial Control Bus
RGB666 + VS, HS, DE converted from 1 pair
Power down mode minimizes power dissipation
The DS99R124Q 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 pat-
terns and does not require a reference clock. A link status
(LOCK) output signal is provided.
FAST random data lock; no reference clock required
Adjustable input receive equalization
LOCK (real time link status) reporting pin
Low EMI FPD-Link output
SSCG option for lower EMI
Adjustable input equalization of the serial input stream pro-
vides 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 signal-
ing, output state select feature, and additional output spread
spectrum generation.
1.8V or 3.3V compatible I/O interface
Automotive grade product: AEC-Q100 Grade 2 qualified
>8 kV HBM and ISO 10605 ESD Rating

Applications
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.
