Hot-selling and scarce ICS8761CYLFT LOW VOLTAGE, LOW SKEW,PCI / PCI-X CLOCK GENERATOR LQFP64 spot stock

Product Descriptions

The ICS8761 is a low voltage, low skew PCI /PCI-X Clock Generator and a member of theHiPerClockS™family of High Performance ClockSolutions from ICS .The ICS8761 has a selectable REF_CLK or crystal input . The REF_CLK inputaccepts LVCMOS or LVTTL input levels .The ICS8761 has afully integrated PLL along with frequency configurable clockand feedback outputs for multiplying and regenerating clockswith“zero delay”. Using a 20MHz or 25MHz crystal or a33.333MHz or 66.666MHz reference frequency, the ICS8761will generate output frequencies of 33.333MHz, 66.666MHz,100MHz and 133.333MHz simultaneously.

The low impedance LVCMOS/LVTTL outputs of the ICS8761are designed to drive 50Ω  series or parallel terminatedtransmission lines .
