Hello, I am using DS90CF384AMTD to interconnect LVDS from the controller to a RGB LCD. Have used RxOUT0-27 as RGB+Control signals as shown in the pg#5 of the datasheet (Figure 4. “16 Grayscale” Test Pattern (DS90CF384A)). But we don't see any image in the LCD. I measured proper 50MHz clock art RcCLK, but the RES pin is keep on toggling and all the R,G,B signals also look noisy. (*Note*: LCD controller SW is also not complete, It is configured for a LVDS LCD with different resolution, so it can be a SW issue as well). What are the basic checks I can do to ensure that there's no hardware issue. Please find attached my schematics and suggest. Thanks.
Hi Darryl, Thanks for the response. We followed the pin mapping as per the datasheet pg#5 (refer attached snapshot). Which is completely different from the one mentioned in the app.note you shared. Where did we go wrong? Can you please help us to understand better why/what is different in the datasheet map. Will changing the pin map as per the app.note solve the issue? Thanks.
