UCC21750: Directly give a differential PWM signal to UCC21750 interlock IN+ and IN- to improve long range noise immunity?

Can I directly give a differential PWM signal to UCC21750 since it has interlock IN+ and IN-? 

For example,  PWM driving signal is from DSP 28379D and then it goes through a differential line driver AM26C31 to get a differential signal. Can I directly use this differential PWM to drive IN+ and IN- of UCC21750 without any differential line receiver(AM26C32)?
