Data Sheet
General Description
The 8S89832I is a high speed 1-to-4 Differential-to-LVDS Fanout
Buffer. The 8S89832I 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 SSTL 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 8S89832I is
packaged in a small 3mm x 3mm 16-pin VFQFN package which
makes it ideal for use in space-constrained applications.

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.
