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-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 1.8 V supply for minimal power dissipation.
