Overview

LOW SKEW, 1-TO-12 LVCMOS/LVTTL FANOUT BUFFER General Description The ICS8312 is a low skew, 1-to-12 LVCMOS/ ICS LVTTL Fanout Buffer and a member of the HiPerClockS™ HiPerClockS™ family of High Performance Clock Solutions from IDT.
The ICS8312 single-ended clock input accepts 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.
The ICS8312 is characterized at full 3.
