ICS8S89834I fiche technique
Low Skew, 2-to-4 LVCMOS/LVTTL-to-
LVPECL/ECL Clock Multiplexer
ICS8S89834I
DATA SHEET
General Description
The ICS8S89834I is a high speed 2-to-4
ICS LVCMOS/LVTTL-to-LVPECL/ECL Clock Multiplexer.
HiPerClockS™ The ICS8S89834I 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 device also has an
output enable pin which may be useful for system test and debug
purposes. The ICS8S89834I is packaged in a small 3mm x 3mm
16-pin VFQFN package which makes it ideal for use in
space-constrained applications.

Four differential LVPECL/ECL output pairs
Two LVCMOS/LVTTL clock inputs
Maximum output frequency: 1GHz
Output skew: 30ps (maximum)
Part-to-part skew: 100ps (maximum)
Propagation delay: 550ps (maximum)
Additive phase jitter, RMS: 0.12ps (typical)
Full 3.3V and 2.5V operating supply modes
-40°C to 85°C ambient operating temperature
Available in lead-free (RoHS 6) package
