LOW SKEW, 1-TO-24 DIFFERENTIAL-
TO-LVCMOS/LVTTL FANOUT BUFFER

IDT / ICS LVCMOS/LVTTL FANOUT BUFFER

ICS8344BYI REV. B February 20, 2009
GENERAL DESCRIPTION
The ICS8344I is a low voltage, low skew fanout
buffer and a member of the HiPerClockS fam-
ily of High Performance Clock Solutions from IDT.
The ICS8344I has two selectable clock inputs.
The CLK0, nCLK0 and CLK1, nCLK1 pairs can
accept most standard differential input levels. The ICS8344I
is designed to translate any differential signal levels to
LVCMOS/LVTTL levels. The low impedance LVCMOS/LVTTL
outputs are designed to drive 50
Ω series or parallel termi-
nated transmission lines. The effective fanout can be in-
creased to 48 by utilizing the ability of the outputs to drive
two series terminated lines. Redundant clock applications
can make use of the dual clock input. The dual clock inputs
also facilitate board level testing. ICS8344I is character-
ized at full 3.3V, full 2.5V and mixed 3.3V input and 2.5V
output operating supply modes.
Guaranteed output and part-to-part skew characteristics make
the ICS8344I ideal for those clock distribution applications de-
manding well defined performance and repeatability.
FEATURES
Twenty-four LVCMOS/LVTTL outputs,
7
Ω typical output impedance
Two selectable differential clock input pairs for redundant
clock applications
CLKx, nCLKx pair can accept the following differential
input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
