www.DataSheet4U.com Integrated Circuit Systems, Inc. ICS85357-01 4:1 OR 2:1 DIFFERENTIAL-TO-3.3V LVPECL / ECL CLOCK MULTIPLEXER FEATURES High speed differential multiplexer. The device can be configured as either a 4:1 or 2:1 multiplexer 1 differential 3.3V LVPECL output 4 selectable CLK, nCLK inputs CLK, nCLK pair can accept the following differential input levels: LVDS, LVPECL, LVHSTL, SSTL, HCSL Maximum output frequency up to 750MHz Translates any single ended input signal to 3.3V LVPECL levels with resistor bias on nCLKx input Part-to-part skew: 150ps (maximum) Propagation delay: 1.5ns (maximum) LVPECL mode operating voltage supply range: VCC = 3.135V to 3.465V, VEE = 0V ECL mode operating voltage supply range: VCC = 0V, VEE = -3.135V to -3.465V 0°C to 70°C ambient operating temperature Industrial temperature information available upon request GENERAL DESCRIPTION The ICS85357-01 is a 4:1 or 2:1 Differential-to3.3V LVPECL / ECL clock multiplexer which can HiPerClockS™ operate up to 750MHz and is a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS85357-01 has 4 selectable clock inputs. The CLK, nCLK pair can accept most standard differential input levels. The device can operate using a 3.3V LVPECL (VEE = 0V, VCC = 3.135V to 3.465V) or 3.3V ECL (VCC = 0V, VEE = -3.135V to -3.465V). The fully differential architecture and low propagation delay make it ideal for use in clock distribution circuits. The select pins...
