ICS858020

www.DataSheet4U.com ICS858020 LOW SKEW, 1-TO-4 DIFFERENTIAL-TO-CML FANOUT BUFFER GENERAL DESCRIPTION The ICS858020 is a high speed 1-to-4 Differentialto-CML Fanout Buffer and is a member of the HiPerClockS™ HiPerClockS™ family of high performance clock solutions from ICS. The ICS858020 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 ICS858020 is packaged in a small 3mm x 3mm 16-pin VFQFN package which makes it ideal for use in space-constrained applications. FEATURES Four differential CML outputs One LVPECL differential clock input IN, nIN pair can accept the following differential input levels: LVPECL, LVDS, CML, SSTL Maximum output frequency: 3.2GHz Output skew: 30ps (maximum) Part-to-part skew: 225ps (maximum) Additive phase jitter, RMS: <0.03ps (typical) Propagation delay: 600ps (maximum) Operating voltage supply range: VCC = 2.375V to 3.63V, VEE = 0V -40°C to 85°C ambient operating temperature Available in both standard (RoHS5) and lead-free (RoHS 6) packages IC S BLOCK DIAGRAM PIN ASSIGNMENT nQ0 IN 1 VT 2 Q0 nQ0 VREF_AC 3 nIN 4 16 15 14 13 12 11 10 9 5 VEE VCC VEE Q0 Q1 nQ1 Q2 nQ2 nQ3 Q1 nQ1 VREF_AC...
