Dual RSDS Transmitter, 24/18-bit color, 40-300Mb/s (SVGA/UXGA/full HDTV) LCD & Plasma display

Overview

This RSDS Transmitter interface IP is based on RSDS “Intra-Panel” Interface Specification rev1.0, dated May 2003 that allow the transfer of digital display data between a Timing Control source (TCON) and Column Drivers of a Flat Panel Display.

The transmitter converts up to 24bits DDR CMOS data (single pixel 18bits, single pixel 24bits, dual pixel 18bits, dual pixel 24bits color) into 24 RSDS, (Reduced Swing Differential Signaling) data streams.

At a maximum dual pixel rate of 150Mhz, RSDS data line speed is 300Mbps, providing a total throughput of 7.2Gbps (900MegaBytes per second).

All the data input/output are independent from each other and can be assigned following any partitioning to support all LCD and Plasma display panel system architectures. (RGB, front/back, even/odd, mixed RGB etc…)

Each pixel channel has 2 identical clock outputs. Strength of the RSDS I/Os can be adjusted from 2mA nominal to 4mA in order to support both 100 and 50 ohm termination.

For convenient routing when TCON is mounted on top or bottom of a display panel, a selectable output data mapping is usually available. LSB or MSB of both channels can be forced to High-Z in order to support 6-bit data color.

This IP can interface with both 1.8V or 3.3V core logic, giving more flexibility for the design.

Designed for LCD and PLASMA display panels
