ICS8312
LOW SKEW, 1-TO-12
LVCMOS / LVTTL FANOUT BUFFER
GENERAL DESCRIPTION
ICS
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.
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.
