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