3 Description

The DS90C187 is a low power Serializer for portable

battery powered that reduces the size of the RGB

interface between the host GPU and the Display.

The DS90C187 Serializer is designed to support dual

pixel data transmission between a Host and a Flat

Panel Display at resolutions of up to QXGA

(2048x1536) at 60 Hz. The transmitter converts up to

48 bits (Dual Pixel 24-bit color) of 1.8-V LVCMOS

data into two channels of 4 data + clock (4D+C)

reduced width interface LVDS compatible data

streams.

DS90C187 supports 3 modes of operation.

• In single pixel mode in/out mode, the device can

drive up to SXGA+ (1400x1050) at 60 Hz. In this

mode, the device converts one bank of 24-bit

RGB data to a one channel 4D+C LVDS data

stream.

• In single pixel in / dual pixel out mode, the device

can drive up to WUXGA+ (1920x1440) at 60 Hz.

In this configuration, the device provides single-todual

pixel conversion and converts one bank of

24-bit RGB data into two channels of 4D+C LVDS

streams at half the pixel clock rate.

In dual pixel in / dual pixel out mode, the device can

drive up to QXGA 2048x1536 at 60Hz or up to

QSXGA 2560x2048 at 30Hz. In this mode, the device

converts 2 channels of 24 bit RGB data into 2

channels of 4D+C LVDS streams. For all the modes,

the device supports 18bpp and 24bpp color.
