... V and 3.3 V LVCMOS clock fan-out buffer Rev. 01 — 10 April 2006 1. General description The PCK9446 is a 2.5 V and 3.3 V compatible clock distribution buffer designed for low-voltage mid-range to high-performance telecom, networking and computing applications. Both 3.3 V, 2.5 V and dual supply voltages are supported for mixed-voltage applications. The PCK9446 offers 10 low skew outputs and 2 selectable inputs for clock redundancy. The outputs are confi ...

... Philips Semiconductors The waveform plots of versus two lines. In both cases the drive capability of the PCK9446 output buffer is more than sufficient to drive 50 measurements in the simulations a delta of only 43 ps exists between the two differently loaded outputs. This suggests that the dual line driving need not be used exclusively to maintain the tight output-to-output skew of the PCK9446. The output waveform in shows a step in the waveform ...
