The 889474 is a high speed 2-to-1 differential multiplexer with integrated 2 output LVDS fanout buffer and internal termination and is a member of the family of high performance clock solutions from IDT. The 889474 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 pins allow other differential signal families such as LVPECL, LVDS, LVHSTL and CML to be easily interfaced to the input with minimal use of external components. The 889474 is packaged in a small 4mm x 4mm 24-pin VFQFN package which makes it ideal for use in space-constrained applications.
