描述 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.
