Low Skew, 2-to-4 LVCMOS/LVTTL-to-
LVPECL/ECL Clock Multiplexer
8S89834I
Data Sheet
General Description
The 8S89834I is a high speed 2-to-4
LVCMOS/LVTTL-to-LVPECL/ECL Clock Multiplexer. The 8S89834I 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 8S89834I is packaged in a small 3mm x 3mm 16-pin VFQFN
package which makes it ideal for use in space-constrained
applications.
Features
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

Absolute Maximum Ratings
NOTE: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device.
These ratings are stress specifications only. Functional operation of product at these conditions or any conditions beyond
those listed in the DC Characteristics or AC Characteristics is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect product reliability.
