www.DataSheet4U.com Integrated Circuit Systems, Inc. ICS85301 2:1 DIFFERENTIAL-TO-LVPECL MULTIPLEXER FEATURES 2:1 LVPECL MUX One LVPECL output Two differential clock inputs can accept: LVPECL, LVDS, CML Maximum input/output frequency: 3GHz Translates LVCMOS/LVTTL input signals to LVPECL levels by using a resistor bias network on nPCLK0, nPCLK0 Propagation delay: 490ps (maximum) Part-to-part skew: 150ps (maximum) Additive phase jitter, RMS: 0.009ps (typical) Full 3.3V or 2.5V operating supply -40°C to 85°C ambient operating temperature Available in both standard and lead-free RoHS compliant packages GENERAL DESCRIPTION The ICS85301 is a high performance 2:1 Differential-to-LVPECL Multiplexer and a member of the HiPerClockS™ HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS85301 can also perform differential translation because the differential inputs accept LVPECL, CML as well as LVDS levels. The ICS85301 is packaged in a small 3mm x 3mm 16 VFQFN package, making it ideal for use on space constrained boards.
