The ICS557G-03LF is one of the most efficient and cost effective ways to generate PCI-Express Gen1 compliant clocks. The device can take a fundamental mode 25MHz crystal or single-ended clock as the input and generates 2 pairs of HCSL outputs of 25MHz, 100MHz, 125MHz, or 200MHz with jitter performance well within the PCI-Express Gen1 requirement. It also features optional down spread functionality to reduce system noise and EMI. The device is packaged in a RoHS compliant 16-pin TSSOP package and is available in commercial and industrial temperature grades.
