The ICS83940 is a low skew, 1-to-18 Fanout Buffer and a member of the H iPerClockSTM HiPerClockSTM family of High Performance Clock Solutions from ICS. The low impedance LVCMOS outputs are designed to drive 50 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.
