Differential LVPECL-To-LVPECL/ECL
Fanout Buffer
ICS8S89831I
General Description
The ICS8S89831I is a high speed 1-to-4 Differential-
to-LVPECL/ECL Fanout Buffer. The ICS8S89831I 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 LVDS,
LVHSTL and CML to be easily interfaced to the input with minimal
use of external components. The device also has an output enable
pin which may be useful for system test and debug purposes. The
ICS8S89831I is packaged in a small 3mm x 3mm 16-pin VFQFN
package which makes it ideal for use in space-constrained
applications.
