Tool/software:
Dear Team,
System Overview:
We have attached a block diagram outlining the subsystem architecture. The signal flow is as follows:
- A video signal originates from the Olympus S7000 system.
- This signal is routed through a Blackmagic SDI to HDMI 3G converter via an SDI cable.
- The HDMI output from the converter is then fed into the TMDS141 IC, which is integrated on our FPGA board.
- The board provides two HDMI outputs, each connected to a 4K monitor using HDMI cables. Cable lengths are specified in the attached diagram.
Issue Observed:
We are experiencing intermittent flickering and complete blackouts on both monitors simultaneously across multiple systems. The issue varies between brief flickers and prolonged signal loss.
Questions:
- Is the TMDS141 IC appropriate for handling this type of HDMI signal transmission?
- Are the HDMI cable lengths within the supported range for this IC?
- What could be the primary cause of the flickering and blackout behavior associated with this IC?
We appreciate your guidance in resolving this issue.
