The ICS557-06 is a one to four differential clock buffer designed for use in PCI-Express applications. The device selects one of the two differential HCSL or LVDS input pairs and fans out to four pairs of differential HCSL or LVDS outputs. Features • Packaged in 20-pin TSSOP • Available in Pb (lead) free package • Operating voltage of 3.3 V • Low power consumption • Input differential clock of up to 200 MHz for HCSL and up to 100 MHz for LVDS • Jitter 100 ps (peak-to-peak) • Output-to-output skew of 50 ps
