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.
