Hi support team.

We would like to adjust 800mV the amplitude of BNC_IO output.

What should be the value of RREF?

We observed 720mV with RREF=680ohm.

Best regards,

Greetings Higa,

You can reduce RREF value however please check eye shape/diagram. Optimum eye shape was achieved with 680-ohm RREF. Suggestion is to not go below 665-ohm RREF value.
