ON Semiconductor has expanded its PureEdge™ high performance clock generation portfolio with the introduction of two best-in-class devices. The NB3N3002 and NB3N5573 are 3.3 V clock generators that create selectable Host Clock Signal Levels (HCSL) and sub-picosecond (ps) jitter quality clocks at 25, 100, 125 and 200 MHz. These devices are appropriate for PCI Express, GigaBit Ethernet, and FBDIMM applications. The PureEdge™ architecture provides increased design flexibility and reduces system cost compared to standard crystal oscillators and competitive silicon-based clock generation devices. The NB3N3002 generates one differential HCSL output clock, while the NB3N5573 delivers dual output. Employing advanced 0.25 micron (um) CMOS technology, the devices significantly outperform competitive devices with phase noise comparable to expensive Surface Acoustic Wave (SAW) crystal oscillators.
