Integrated Circuit Systems, Inc. www.DataSheet4U.com PRELIMINARY ICS853011C LOW SKEW, 1-TO-2 DIFFERENTIAL-TO-2.5V/3.3V LVPECL/ECL FANOUT BUFFER GENERAL DESCRIPTION The ICS853011C is a low skew, high perfor- ICS mance 1-to-2 Differential-to-2.5V/3.3V LVPECL/ HiPerClockS™ ECL Fanout Buffer and a member of the HiPerClockS ™ family of High Performance Clock Solutions from ICS. The ICS853011C 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 ICS853011C ideal for those clock distribution applications demanding well defined perfor mance and repeatability. FEATURES • 2 differential 2.5V/3.3V LVPECL / ECL 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: 250ps (typical) • LVPECL mode operating voltage supply range: VCC = 2.375V to 3.8V, VEE = 0V • ECL mode operating voltage supply range: V = 0V, V = -3.8V to -2.375V CC EE • -40°C to 85°C ambient operating temperature • Pin compatible with MC100LVEP11 and SY100EP11U BLOCK DIAGRAM PIN ASSIGNMENT PCLK nPCLK Q0 nQ0 Q1 nQ1 Q0 nQ0 Q1 nQ1 1 2 3 4 8 Vcc 7 PCLK 6 nPCLK 5 VEE ICS853011C 8-Lead SOIC 3.90mm x 4.90mm x 1.37mm package body M Package Top View ICS853011C 8-Lead TSSOP, 118 mil 3mm x 3mm x 0.95mm package body G Package Top View The Preliminary Information presented herein represents a product in prototyping or pre-production.
