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 V
other differential signal families such as LVPECL, LVDS,
LVHSTL and CML to be easily interfaced to the input with
minimal use of exter nal components. The ICS889474 is
packaged in a small 4mm x 4mm 24-pin VFQFN package
which makes it ideal for use in space-constrained applications.
