When I used the CDCV304 clock buffer, I find a documentation that discussed unused output pins about Clocking Design in TI 's Web. The number of the documentation is "SNVA745" ,named "Clocking Design Guidelines: Unused Pins". On the page 9 of the document, it says "TI recommends leaving the unused outputs floating without connecting any traces to the output pin". About this point ,I have some questions:
1. why leaving the unused outputs floating without connecting any traces to the output pin? And if I do this, whether it will
generate EMI to my PCB?
2. Can I use a capacitor to connect out put unused pins to ground to reduce the EMI of my PCB?
