ON Semiconductor Releases New PureEdge(TM) High-Performance Clock Generation Devices for Telecom, Networking and Consumer Applications



PLL-based devices create ultra low jitter quality clocks that improve timing accuracy, increase design flexibility and lower cost for PCI Express, Ethernet and FBDIMM applications

PHOENIX, Ariz. Dec. 11, 2007 - ON Semiconductor (Nasdaq: ONNN), a global leader in power semiconductor solutions, today announced the expansion of its PureEdge(TM) high performance clock generation portfolio with the introduction of two best-in-class devices - the NB3N3002 and NB3N5573.

"Aggressively growing our timing business will continue to be a key focus as we move into 2008," said Dan Huettl, ON Semiconductor general manager of the Advanced Logic Division. "Our PureEdge(TM) portfolio is proving to be the industry's best available PLL-based, low phase noise, clock generation technology. As we further expand the PureEdge(TM) family, we expect to continue to gain recognition as a key player in the clock generation market space and a provider of complete solutions for the entire clock tree."

The NB3N3002 and NB3N5573 are 3.3 volt (V) clock generators that create selectable Host Clock Signal Levels (HCSL) and sub-picosecond (ps) jitter quality clocks at 25 Megahertz (MHz), 100 MHz, 125MHz and 200 MHz. These devices are ideal for PCI Express, GigaBit Ethernet, and FBDIMM applications. The PureEdgeTM 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. These devices generate high quality clocks from a low cost 25 MHz crystal with four selectable output frequencies and integrated 1:2 fanout buffer (NB3N5573). The device provides phase noise of -130 decibels relative to the carrier per hertz (dBc/Hz) at 100 kilohertz (KHz) offset from the carrier frequency.

Like all of ON Semiconductor's PureEdge(TM) devices, these new clock generators free up more of the system designer's precious timing budget and offer true design flexibility. Silicon-based clock generation ICs, such as the NB3N3002 and NB3N5573, are inherently simpler to manufacture than expensive crystal oscillators. This results in lower overall system costs and vastly shorter lead times. The NB3N5573 is a pin compatible drop in replacement for the competitive function device ICS557-3. The NB3N5573 provides much better jitter performance and was implemented without the Spread Spectrum feature making it a better value where SSM is not required.

"ON Semiconductor continues to provide customers with competitively priced timing solutions that deliver the highest performance and best quality." said Huettl. "The company's reputation for solid delivery and superior customer service serves to further strengthen the confidence of our customers. During the coming year, we plan to introduce additional PureEdgeTM products that target the demanding technological needs and unique industry challenges of the marketplace."
