ADN4604 SDI interface

I would like to know if it is possible to connect directly HD-SDI signals (1.5 Gbps) to the ADN4604 inputs and outputs pin and if yes what are the recommended connection schematics.


HD-SDI interface use 75 ohms asymetrical electrical interface while ADN4604 is designed for 100 ohms differential CML signals.

So do we need to add serial resistors? additional termination resistors?

What should we connect to the negative input or output pins (INx and ONx) of the signals? and to the Vtti and Vtto voltage pins?


Our application will use 5m coaxial cables : are the integrated equalisers and drivers good enough to handle this cable length?


Thank you for your help,


Best regards,
