very low output skew, making it suitable for use in demand-
ing 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 ICS889834 is packaged in a small 3mm x 3mm
16-pin VFQFN package which makes it ideal for use in space-
constrained applications.
