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 VDDIO 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).
