DS90UR905Q-Q1: DS90UR905+DS90UR908 work abnormally

Part Number: DS90UR905Q-Q1


Hello,

Our customer  use DS90UR905+DS90UR908, and find that using select IO of FPGA couldn't decode the LVDS data of UR908, the RGB data is all 0XFF and didn't have stable HS,VS and DE signal. But DS90UR907+DS90UR908 he used has no problem.  65Mhz pixel clock, 1024*768@60Hz resolution, the hardware configuration  is as following:

UR905: config[1:0]=00,vodsel=1,RFB=0

UR908:LFMODE=0,MAPSEL=1,config[1:0]=01,VODSEL=0。

Could you please give me some advice? 

Best regards

Kailyn
