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).
