PRELIMINARY
GENERAL DESCRIPTION
The ICS85105I is a low skew, high performance 1-
to-5 Differential-to-0.7V HCSL Fanout Buffer and
a member of the HiPerClockS family of High
Perfo r mance Clock Solutions from IDT. The
ICS85105I has two selectable clock inputs. The
CLK0, nCLK0 pair can accept most standard differential
input levels. The single-ended CLK1 can accept LVCMOS or
LVTTL input levels. The clock enable is internally synchronized
to eliminate runt clock pulses on the outputs during asynchro-
nous assertion/deassertion of the clock enable pin.
Guaranteed output and part-to-part skew characteristics make
the ICS85105I ideal for those applications demanding well
defined performance and repeatability.
FEATURES
Five 0.7V differential HCSL outputs
Selectable differential CLK0, nCLK0 or LVCMOS inputs
CLK0, nCLK0 pair can accept the following differential
input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL
CLK1 can accept the following input levels:
LVCMOS or LVTTL
Maximum output frequency: 500MHz
Translates any single-ended input signal to 3.3V
HCSL levels with resistor bias on nCLK input
Output skew: 75ps (typical), TSSOP package
TBD, SOIC package
Part-to-part skew: 300ps (typical)
Propagation delay: 2.4ns (typical)
Additive phase jitter, RMS: 0.31ps (typical)
3.3V operating supply
-40°C to 85°C ambient operating temperature
Available in both standard (RoHS 5) and lead-free (RoHS 6)
