Description

The 87158 is a high performance 1-to-6 LVPECL-to- HCSL/LVCMOS ClockGenerator. The 87158 has one differential input (which can accept LVDS, LVPECL, LVHSTL, SSTL, HCSL), six differential HCSL output pairs and two complementary LVCMOS/LVTTLoutputs. 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. The primary use of the 87158 is in Intel® E8870 chipsets that use Intel® Pentium 4 processors. The 87158 converts the differential clock from the main system clock into HCSL clocks used by Intel® Pentium 4 processors. However, the 87158 is a highly flexible, general purpose device that operates up to 600MHz and can be used in any situation where Differential-to-HCSL translation is required.
