ICS83940I-01
LOW SKEW, 1-TO-18
LVPECL-TO-LVCMOS / LVTTL FANOUT BUFFER
PRELIMINARY
GENERAL DESCRIPTION
The ICS83940I-01 is a low skew, 1-to-18
LVPECL-to-LVCMOS/LVTTL Fanout Buffer and a
member of the HiPerClockSfamily of High Per-
for mance Clock Solutions from ICS. The
ICS83940I-01 has two selectable clock inputs.
The PCLK, nPCLK pair can accept LVPECL, CML or SSTL
input levels. The single ended clock input accepts LVCMOS
or LVTTL input levels. The low impedance LVCMOS/LVTTL
outputs are designed to drive 50
series or parallel termi-
nated 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 ICS83940I-01 is characterized at full 3.3V, full 2.5V and
mixed 3.3V input and 2.5V output operating supply modes. Guar-
anteed output and part-to-part skew characteristics make the
ICS83940I-01 ideal for those clock distribution applications de-
manding well defined performance and repeatability.
