ICS8344I
LOW SKEW, 1-TO-24
DIFFERENTIAL-TO-LVCMOS FANOUT BUFFER
GENERAL DESCRIPTION
The ICS8344I is a low voltage, low skew fanout
buffer and a member of the HiPerClockS
family of High Performance Clock Solutions from
ICS. The ICS8344I has two selectable clock in-
puts. The CLK0, nCLK0 and CLK1, nCLK1 pairs
can accept most standard differential input levels. The
ICS8344I is designed to translate any differential signal lev-
els to LVCMOS levels. The low impedance LVCMOS outputs
are designed to drive 50
series or parallel terminated trans-
mission lines. The effective fanout can be increased to 48 by
utilizing the ability of the outputs to drive two series termi-
nated lines. Redundant clock applications can make use of
the dual clock input. The dual clock inputs also facilitate board
level testing. ICS8344I is characterized 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 applica-
tions demanding well defined performance and repeatability.
FEATURES
24 LVCMOS outputs, 7 typical output impedance
2 selectable differential clock input pairs for redundant clock
applications
CLKx, nCLKx pair can accept the following differential input
levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL
Maximum output frequency up to 100MHz
Translates any single-ended input signal to LVCMOS with
resistor bias on nCLK input
Multiple output enable pins for disabling unused outputs in
reduced fanout applications
Output skew: 275ps (maximum)
Part-to-part skew: 600ps (maximum)
Bank skew: 150ps (maximum)
3.3V, 2.5V or mixed 3.3V, 2.5V operating supply modes
-40°C to 85°C ambient operating temperature
