Hello,
As below photo and diagram show, the EVM 4422 we just bought seems cannot link with i-chips Vx1 board, whether the cable been connected, the Vby1_HPD always lit on...
Please help to figure out what might cause this failure
Thank you,
Gary Lee
Gary,
Have you confirmed that the timings for the I-Chips product is compatible with the recommended and alternate timings supported by the Vx1 input that are listed in DLP660TE_Vx1_Input_Video_Timings.xls? This file is available in: DLP660TE-FW: DLPC4422 Controller Support Firmware for DLP660TE DMD
Make note that vx1 in DLPLCRDC4422EVM operates at 600MHz.
Here's a summary from the recommended timings:
The excel sheet provides some additional alternatives.
Regards,
Mike
