ADV7842 oscillator, XTALP / XTALN

Can I use a CMOS 1.8V oscillator on the XTALP pin (B16)? Or does it have to be differential?

I’m looking at Table 100 (unused pins) in the UG-214 manual. It says that B16 and C16 are “always connected to 28.63636 MHz crystal.”

What do I do with C16 (XTALN) if I’m only using B16 (XTALP)?

Thanks.
