GENERAL DESCRIPTION

The ICS85401 is a high performance 2:1 Differential-to-LVDS Multiplexer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS85401 can also perform differential translation because the differential inputs accept LVPECL, CML as well as LVDS levels. The ICS85401 is packaged in a small 3mm x 3mm 16 VFQFN package, making it ideal for use on space constrained boards.
