The 556-04 is a low-skew, crystal input compatible clock buffer with oscillator. This device offers the lowest skew. See the 552-02 for a 1-to-8 low skew buffer. For more than eight outputs see the MK74CBxxx Buffalo™ series of clock drivers. Renesas makes many non-PLL and PLL-based low-skew output devices. Contact us for all of your clocking needs.
