The DS90URxxx-Q1 chipset translates a
24-bit parallel bus into a fully transparent data/control FPD-Link II LVDS serial
stream with embedded clock information. This chipset is designed for driving
graphical data to displays requiring 18-bit color depth: RGB666 + HS, VS, DE + three
additional general-purpose data channels. This single serial stream simplifies
transferring a 24-bit bus over PCB traces and cable by eliminating the skew problems
between parallel data and clock paths. The device saves system cost by narrowing
data paths that in turn reduce PCB layers, cable width, and connector size and
pins.
The DS90URxxx-Q1 incorporates FPD-Link
II LVDS signaling on the high-speed I/O. FPD-Link II LVDS provides a low-power and
low-noise environment for reliably transferring data over a serial transmission
path. By optimizing the Serializer output edge rate for the operating frequency
range, EMI is further reduced.
In addition, the device features
pre-emphasis to boost signals over longer distances using lossy cables. Internal
DC-balanced encoding and decoding is used to support AC-coupled interconnects. Using
TI’s proprietary random lock, the parallel data of the Serializer are randomized to
the Deserializer without the need of REFCLK.
