can accept most standard differential input levels. The
LVCMOS_CLK can accept LVCMOS or LVTTL input levels.
The low impedance LVCMOS outputs are designed to drive
50
effective fanout can be increased from 12 to 24 by utilizing
the ability of the outputs to drive two series terminated lines.
The ICS83948I-01 is characterized at 3.3V core/3.3V output.
Guaranteed output and part-to-part skew characteristics make
the ICS83948I-01 ideal for those clock distribution applications
demanding well defined performance and repeatability.

The ratio of R1 and R2 might need to be adjusted to position the V_REF in the center of the input voltage swing.
