Integrated Circuit Systems, Inc. ICS87158 www.DataSheet4U.com 1-TO-6, LVPECL-TO-HCSL/LVCMOS ÷1, ÷2, ÷4 CLOCK GENERATOR GENERAL DESCRIPTION The ICS87158 is a high performance 1-to-6 LVPECL-to-HCSL/LVCMOS Clock Generator HiPerClockS™ and is a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS87158 has one differential input (which can accept LVDS, LVPECL, LVHSTL, SSTL, HCSL), six differential HCSL output pairs and two complementary LVCMOS/LVTTL outputs. The six HCSL output pairs can be individually configured for divide-by-1, 2, and 4 or high impedance by use of select pins. The two complementary LVCMOS/LVTTL outputs can be configured for divide by 2, divide by 4, high impedance, or driven low for low power operation. FEATURES Six HCSL outputs Two LVCMOS/LVTTL outputs One Differential LVPECL clock input pair PCLK, nPCLK supports the following input types: LVDS, LVPECL, LVHSTL, SSTL, HCSL Maximum output frequency: 600MHz (maximum) Output skew: 100ps (maximum) Propagation delay: 4ns (maximum) 3.3V operating supply 0°C to 85°C ambient operating temperature Available in both standard and lead-free RoHS compliant packages Industrial temperature information available upon request IC S The primary use of the ICS87158 is in Intel ® E8870 chipsets that use Intel ® Pentium 4 processors. The ICS87158 converts the differential clock from the main system clock into HCSL clocks used by Intel ® Pentium 4 processors. However, the ...
