Output signal of channel differential transceiver

baiyujing

Dear Wolfspeed Technicians,

I am a master's student majoring in power electronics. I am studying the evaluation board CGD12HBXMP and its supporting 2-Channel Differential Transceiver CGD12HB00D. In the output signal of CGD12HB00D, the typical value of the high level voltage is 3.4V(as shown in figure1). But in CGD12HBXMP, the minimum value of the input high level voltage is 3.5V(as shown in figure2). How does CGD12HB00D provide the high level to CGD12HBXMP? Is it always working in an overload state? Because I see that the maximum output voltage high level of CGD12HB00D is not given.

Sincere wishes.
