GENERAL DESCRIPTION

The ICS83940-01 is a low skew, 1-to-18 Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The low impedance LVCMOS outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 18 to 36 by utilizing the ability of the outputs to drive two series terminated lines. The differential clock input is designed to accept any differential input levels including LVPECL.

The ICS83940-01 is characterized at full 3.3V, full 2.5V and mixed 3.3V input and 2.5V output operating supply modes. Guaranteed output and part-to-part skew characteristics make the ICS83940 ideal for those clock distribution applications demanding well defined performance and repeatability.
