ENERAL

ESCRIPTION

The ICS8312 is a low skew, 1-to-12 LVCMOS /

LVTTL Fanout Buffer and a member of the

HiPerClockS™

HiPerClockS™family of High Performance Clock

Solutions from ICS. The ICS8312 single ended

clock input accepts LVCMOS or LVTTL input lev-

els. 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.

ICS

The ICS8312 is characterized at full 3.3V, 2.5V, and 1.8V,

mixed 3.3V/2.5V, 3.3V/1.8V and 2.5V/1.8V output operating

supply modes. Guaranteed output and part-to-part skew char-

acteristics along with the 1.8V output capabilities makes the

ICS8312 ideal for high performance, single ended applica-

tions that also require a limited output voltage.
