LOW SKEW, 1-TO-2, DIFFERENTIAL-TO-
2.5V, 3.3V LVPECL FANOUT BUFFER
GENERAL DESCRIPTION
The ICS858012 is a high speed 1-to-2 Differential-
ICS to-2.5V, 3.3V LVPECL Fanout Buffer and is a
HiPerClockS™ member of the HiPerClockS™ family of high
performance clock solutions from ICS. The
ICS858012 is optimized for high speed and very
low output skew, making it suitable for use in demanding
applications such as SONET, 1 Gigabit and 10 Gigabit
Ethernet, and Fibre Channel. The internally terminated
differential input and VREF_AC pin allow other differential signal
families such as LVPECL, LVDS, LVHSTL and HCSL to be
easily interfaced to the input with minimal use of external
components. The ICS858012 is packaged in a small 3mm x
3mm 16-pin VFQFN package which makes it ideal for use in
space-constrained applications.
FEATURES
Two differential LVPECL outputs
One differential LVPECL clock input
IN, nIN pair can accept the following differential input
levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL
Output frequency: 2GHz (typical)
Output skew: <15ps (typical)
Part-to-part skew: TBD
Additive phase jitter, RMS: TBD
Propagation delay: 350ps (typical)
Operating voltage supply range:
VCC = 2.375V to 3.63V, VEE = 0V
-40°C to 85°C ambient operating temperature
Availabe in both standard and lead-free RoHS compliant
packages
