DESCRIPTION
The DS90C187 is a Low Power Serializer for portable
battery powered application 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 Host and Flat Panel
Display up to QXGA 2048x1536 at 60Hz resolutions.
The transmitter converts up to 48 bits (Dual Pixel 24
bit color) of 1.8V 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 60Hz. In this mode, the device
converts one bank of 24 bit RGB data to one channel
of 4D+C LVDS data stream. In single pixel in / dual
pixel out mode, the device can drive up to WUXGA+
1920x1440 at 60Hz. 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. 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.
The DS90C187 is offered in a small 92 pin dual row
VQFN package and features single 1.8V supply for
minimal power dissipation.
