Both the input and output are single-ended (LVCMOS/LVTTL in, LVCMOS out); there is no differential pair like LVPECL or LVDS. That simplifies the layout — no termination resistors or bias networks — but it also means the buffer does not reject common-mode noise on the input. Keep the trace short and route it away from switching power rails to avoid coupling into the clock path.
200 MHz. That is the ceiling for the LVCMOS output; the input side is rated for the same frequency. Good for distributing a 100 MHz or 125 MHz reference, but not for gigabit-rate clocks.
