DS90CF388 - Dual Pixel LVDS Display Interface

Datasheet Summary

Description

The DS90C387/DS90CF388 transmitter/receiver pair is designed to support dual pixel data transmission between Host and Flat Panel Display up to QXGA resolutions.

The transmitter converts 48 bits (Dual Pixel 24-bit color) of CMOS/TTL data into 8 LVDS (Low Voltage Differential Signalling) data streams.

Features

  • n Complies with OpenLDI specification for digital display interfaces n 32.5 to 112/170MHz clock support n Supports SVGA through QXGA panel resolutions n Drives long, low cost cables n Up to 5.38Gbps bandwidth n Pre-emphasis reduces cable loading effects n DC balance data transmission provided by transmitter reduces ISI distortion n Deskews +/.
  • 1 LVDS data bit time of pair-to-pair skew at receiver inputs; intra-pair skew tolerance of 300ps n Dual pixel architecture supports interface to GU.

DS90C387/DS90CF388 Dual Pixel LVDS Display Interface (LDI)-SVGA/QXGA PRELIMINARY May 2000 DS90C387/DS90CF388 Dual Pixel LVDS Display Interface (LDI)-SVGA/QXGA General Description The DS90C387/DS90CF388 transmitter/receiver pair is designed to support dual pixel data transmission between Host and Flat Panel Display up to QXGA resolutions. The transmitter 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 are also supported.
