Low Skew, 1-to-4 Differential-to-LVDS
Fanout Buffer
8S89832I
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.

NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device
is mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal
equilibrium has been reached under these conditions.
All parameters are measured at 1.5GHz unless otherwise noted.
NOTE 1: Measured from the differential input crossing point to the differential output crossing point.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.
Measured at the output differential cross points.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
NOTE 4: Defined as skew between outputs on different devices operating at the same supply voltage, same temperature, same frequency and
with equal load conditions. Using the same type of inputs on each device, the outputs are measured at the differential cross points.
