ICS855011

PRELIMINARY Integrated Circuit Systems, Inc. ICS855011 www.DataSheet4U.com LOW SKEW , 1-TO-2 DIFFERENTIAL-TO-2.5V/3.3V CML FANOUT BUFFER GENERAL DESCRIPTION The ICS855011 is a low skew, high performance 1-to-2 Differential-to-2.5V/3.3V CML HiPerClockS™ Fa n o u t B u f fe r a n d a m e m b e r o f t h e HiPerClockS ™ family of High Perfor mance Clock Solutions from ICS. The ICS855011 is characterized to operate from either a 2.5V or a 3.3V power supply. Guaranteed output and par t-to-par t skew characteristics make the ICS855011 ideal for those clock distribution applications demanding well defined perfor mance and repeatability. FEATURES 2 differential 2.5V/3.3V CML outputs 1 differential PCLK, nPCLK input pair PCLK, nPCLK pair can accept the following differential input levels: LVPECL, LVDS, CML, SSTL Output frequency: >3GHz Translates any single ended input signal to 3.3V LVPECL levels with resistor bias on nPCLK input Output skew: 5ps (typical) Part-to-part skew: TBD Propagation delay: 242ps (typical) Operating voltage supply range: VCC = 2.375V to 3.8V, VEE = 0V -40°C to 85°C ambient operating temperature ICS BLOCK DIAGRAM PCLK nPCLK Q0 nQ0 Q1 nQ1 PIN ASSIGNMENT Q0 nQ0 Q1 nQ1 1 2 3 4 8 7 6 5 Vcc PCLK nPCLK VEE ICS855011 8-Lead SOIC 3.90mm x 4.90mm x 1.37mm package body M Package Top View The Preliminary Information presented herein represents a product in prototyping or pre-production.
