My customer needs to isolate its HDMI (from TX output to Screen/HDMI RX input).
Is there an isolator at ADI which can support HDMI rates and levels?
If not, is there a circuit note or application note available?
The recently released CN-0422 circuit note describes a complete solution for galvanic isolation of the HDMI 1.3a protocol using ADN4654 1.1Gbps LVDS isolators. The circuit note includes details on coupling between TMDS and LVDS signalling, and isolation of the DDC, CDC and HPD signals.
It's also available as an evaluation board, EVAL-CN0422-EBZ for the plug and play addition of galvanic isolation to a HDMI 1.3 interface.
