www.DataSheet4U.com Integrated Circuit Systems, Inc. ICS889831 LOW SKEW, 1-TO-4 DIFFERENTIAL LVPECL-TO-LVPECL/ECL FANOUT BUFFER FEATURES 4 differential LVPECL/ECL outputs IN, nIN pair can accept the following differential input levels: LVPECL, LVDS, CML, SSTL 50Ω internal input termination to VT Maximum output frequency: > 2.1GHz Output skew: 30ps (maximum) Part-to-part skew: 185ps (maximum) Additive phase jitter, RMS: 0.27ps (typical) Propagation delay: 570ps (maximum) LVPECL mode operating voltage supply range: VCC = 2.5V ± 5%, 3.3V ± 5%, VEE = 0V ECL mode operating voltage supply range: VCC = 0V, VEE = -3.3V ± 5%, 2.5V ± 5% -40°C to 85°C ambient operating temperature Lead-Free package fully RoHS compliant GENERAL DESCRIPTION The ICS889831 is a high speed 1-to-4 Differentialto-LVPECL/ECL Fanout Buffer and is a member HiPerClockS™ of the HiPerClockS™ family of high performance clock solutions from ICS. The ICS889831 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 pin allow other differential signal families such as LVDS, LVHSTL and CML to be easily interfaced to the input with minimal use of external components. The device also has an output enable pin which may be useful for system test and debug purposes. The ICS889831 is packaged in a small 3mm x 3mm 16-pin VFQFN...
