The ICS556-04 is a low-skew, crystal input compatible clock buffer with oscillator. This device offers the lowest skew. See the ICS552-02 for a 1-to-8 low skew buffer. For more than eight outputs see the MK74CBxxx BuffaloTM series of clock drivers. ICS makes many non-PLL and PLL-based low-skew output devices. Contact ICS for all of your clocking needs. Feat.
