ICS8302LOW SKEW, 1-TO-2LVCMOS / LVTTL FANOUT BUFFER

GENERAL DESCRIPTIONThe ICS8302 is a low skew, 1-to-2 LVCMOSFanout Buffer and a member of theHiPerClockS™ family of High PerformanceClock Solutions from ICS. The ICS8302 has asingle ended clock input. The single ended clockinput accepts LVCMOS or LVTTL input levels. The ICS8302features a pair of LVCMOS/LVTTL outputs. The ICS8302 ischaracterized at full 3.3V for input VDD, and mixed 3.3V and2.5V for output operating supply modes (VDDO). Guaran-teed output and part-to-part skew characteristics makethe ICS8302 ideal for clock distribution applications demand-ing well defined performance and repeatibility.FEATURES

•2 LVCMOS / LVTTL outputs•LVCMOS / LVTTL clock input accepts LVCMOSor LVTTL input levels

•Maximum output frequency: 200MHz•Output skew: 25ps (typical)•Part-to-part skew: 250ps (typical)•Small 8 lead SOIC package saves board space•Full 3.3V or 3.3V core, 2.5V supply modes•0°C to 70°C ambient operating temperature•Lead-Free package available•Industrial temperature information available upon request
