Low Power 1.8V FPD-Link (LVDS) Serializer
General Description
The DS90C185 is a Low Power Serializer for portable battery
powered applications that reduces the size of the RGB inter-
face 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 com-
monly supported in LCD modules with “LVDS” or FPD-Link /
FlatLink single-pixel input interfaces.
Displays up to 1400 x 1050 @ 60 fps are supported with
24bpp in color depth. 18bpp may also be supported by a ded-
icated mode with a 3D+C output. Power Dissipation is mini-
mized by the full LVCMOS design and 1.8V powered core and
V_DDIO rails.
The DS90C185 is offered in the small 48 pin QFN package
and features single 1.8V supply operation for minimum power
dissipation (50mW typ).
