Product Summary

The DS90C387AVJD is a Dual Pixel LVDS Display Interface. It is designed to support dual pixel data transmission between Host and Flat Panel Display up to QXGA resolutions. The transmitter of the DS90C387AVJD converts 48 bits (Dual Pixel 24-bit color) of CMOS/TTL data into 8 LVDS (Low Voltage Differential Signalling) data streams. Control signals (VSYNC, HSYNC, DE and two user-defined signals) are sent during blanking intervals. At a maximum dual pixel rate of 112MHz, LVDS data line speed is 672Mbps, providing a total throughput of 5.38Gbps (672 Megabytes per second). Two other modes of the DS90C387AVJD are also supported. 24-bit color data (single pixel) can be clocked into the transmitter at a maximum rate of 170MHz. In this mode, the transmitter provides single-to-dual pixel conversion, and the output LVDS clock rate is 85MHz maximum. The third mode provides inter-operability with FPD-Link devices.
