Integrated Circuit Systems, Inc. ICS83905 LOW SKEW, 1:6 CRYSTAL INTERFACE-TOLVCMOS / LVTTL FANOUT BUFFER The ICS83905 is a low skew, 1-to-6 LVCMOS / LVTTL Fanout Buffer and a member of the HiPerClockS family of High Performance Clock Solutions from ICS. The low impedance LVCMOS/ LVTTL outputs are designed to drive 50Ω series or parallel terminated transmission lines. The effective fanout can be increased from 6 to 12 by utilizing the ability of the outputs to drive two series terminated lines.
