Clock Generator 56-Pin TSSOP T/R

The ICS87159 is a high performance 1-to-8 Differential-toHCSL/LVCMOS Clock Generator. The ICS87159 has one differential input (which can accept LVDS, LVPECL, LVHSTL, SSTL, HCSL), eight differential HCSL output pairs and two complementary LVCMOS/LVTTL outputs. The eight HCSL output pairs can be 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 ICS87159 is in *Intel E8870 chipsets that use *Intel Pentium 4 processors. The ICS87159 converts the differential clock from the main system clock into HCSL clocks used by *Intel Pentium 4 processors. However, the ICS87159 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.
