DESCRIPTION
The DS90C185 is a low-power serializer for portable
battery-powered applications that reduces the size of
the RGB interface between the host GPU and the
display.
24-bit RGB plus three video control signals are
serialized and translated to LVDS-compatible levels
and sent as a 4 data + clock (4D+C) reduced-width
LVDS compatible interface. The LVDS Interface is
compatible with FPD-Link (1) deserializers and many
LVDS based displays. These interfaces are
commonly supported in LCD modules with “LVDS” or
FPD-Link / FlatLink single-pixel input interfaces.
Displays up to 1400x1050 at 60 fps are supported
with 24-bpp color depth. 18 bpp may also be
supported by a dedicated mode with a 3D+C output.
Power dissipation is minimized by the full LVCMOS
design and 1.8-V powered core and V_DDIO rails.
The DS90C185 is offered in the small 48-pin WQFN
package and features single 1.8-V supply operation
for minimum power dissipation (50 mW typ).
