... Low voltage CMOS clock driver Rev. 01 — 13 December 2005 1. General description The PCK946 is a low voltage CMOS clock buffer. The 10 outputs can be configured into a standard fan-out buffer or into 1 and designed and optimized to drive 50 With output-to-output skews of 350 ps, the PCK946 is ideal as a clock distribution chip for synchronous systems which need a tight level of skew from a large number of outputs ...
