3 Description

The DS90C189-Q1 is a low power bridge for

automotive applications that reduces the size of the

RGB interface between the host GPU and the Display.

The DS90C189-Q1 Bridge is designed to support

single 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

24 bits (Single 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.

DS90C189-Q1 supports 2 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-to-

dual 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.

For all the modes, the device supports 24bpp color.

The DS90C189-Q1 is offered in a small 64 pin QFN

package and features single 1.8 V supply for minimal

power dissipation.
