... Jitter: <200 ps peak to peak, <25 ps RMS • Compatible with Pentium™-based processors Functional Description The CY7B9910 and CY7B9920 Low Skew Clock Buffers offer low-skew system clock distribution. These multiple-output clock drivers optimize the timing of high-performance comput- er systems. Eight individual drivers can each drive terminated ...
