Thanks for your help. But i need a Splitter not a switch. I got an ic MAX3845 which is 2:4 fan out switch and cable driver but the problem is that it can split the input to all the outputs if the input is not HDCP compliant. I need a splitter ic which can split the signal which is HDCP compliant. please suggest me a solution.

Thanks ,

The TMDS442 can be configured as a fan out (just connect both outputs to the same input), but you will not be able to transmit HDCP encoded data to both sinks simultaneously. To do this, the fanout must have a full HDCP engine on each output to encrypt signals to each sink.
