DS90C187 Overview
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. 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. Typical Application 1.8 V LVCMOS (24 bit RGB + HS/VS/DE) 1.8 V GPU ± Jacinto 6 Single Pixel R[7:0] G[7:0] B[7:0]
