There is no restriction or limitations on the component. Kindly follow the datasheet to get more information. Are you facing any issue while using this component?
There is no SPDIF Receiver component. And building one from scratch in the UDB is not trivial. So I have the same question. I currently am designing an interface to communicate between 2 PSoC 3's using the SPDIF Transmitter as one component in one, and would like to interface to the other with an SPDIF stream. This way, I can get audio data and protocol data relatively fast through one wire.
