Dual RSDS Transmitter, 30-bit color, 80-400Mb/s (SVGA/Full HDTV@120Hz)

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 30-bit DDR CMOS data (single pixel 24-bit, single pixel 30-bit, dual pixel 24-bit, dual pixel 30-bit color) into 30 RSDS, (Reduced Swing Differential Signaling) data streams.

At a maximum dual pixel rate of 200Mhz, RSDS data line speed is 400Mbps, providing a total throughput of 12Gbps (1.5GygaBytes 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 3 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 termination. Tree extra clock output are also provided.

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 24-bit data color.

This IP can interface with both 1.2V or 3.3V core logic, giving more flexibility for the design.
