Fanout Buffer w/Internal Termination
8S89833
Data Sheet
General Description
The 8S89833 is a high speed 1-to-4 Differential-to-LVDS Fanout
Buffer with Internal Termination. The 8S89833 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, 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 8S89833 is packaged in a small 3mm x 3mm 16-pin VFQFN
package which makes it ideal for use in space-constrained
applications.
