AM3352: LVDS connections

Nicky Wang

Part Number: AM3352

I plan to use AM3352 and LVDS transformer/ DS90CR285MTDX/NOPB as LCD display solution,they will operate in RGB888 mode. From AM3352's errata (Literature Number: SPRZ360I), The blue and red color assignments to the LCD data pins are reversed when operating in RGB888 (24bpp) mode compared to RGB565 (16bpp) mode. Please check if LCD signal connection from AM3352 to DS90CR285MTDX in my design is correct?

Hi,

You can use this wiki as reference: processors.wiki.ti.com/.../LCD_connectivity
The proper signals can be seen in the AM335x Errata Usage Note 3.1.1.

Thanks for your feedback. But it seems the pin sequence (DSS_xx<==>RGBn in wiki is different to LCD_DATA[xx]<==>RGBn in Errata ) . For example, DSS_16=R[0] in wiki, but LCD_DATA[21]=R[0] in Errata.

On the processor side you need to use the color assignments as listed in the Errata.

Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
