PLL-based generators cut clocking costs
3.3V clock generators create selectable host clock signal levels and subpicosecond jitter quality clocks at 25, 100, 125 and 200MHz.
ON Semiconductor has expanded its PureEdge 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", says Dan Huettl, ON Semiconductor General Manager of the Advanced Logic Division

Low jitter for drop-in PLL synthesiser replacement
The NBC12429FN is a 3.3/5.0V programmable PLL clock synthesiser that provides a 25 to 400MHz system clock ideal for the primary timing signals in networking, telecomms and test hardware.
Meritorious performance from N-channel MOSFETs
Continuing the expansion of its portfolio of low-voltage power MOSFETs for switching and power management applications, ON Semiconductor has released a range of new N-channel devices.
"Our PureEdge portfolio is proving to be the industry's best available PLL-based low-phase-noise clock-generation technology".
"As we further expand the PureEdge 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 3.3V clock generators that create selectable host clock signal levels (HCSL) and subpicosecond jitter quality clocks at 25, 100, 125 and 200MHz.

PFC controllers reduce need for overdesign
The NCP1650 is a novel power-factor correction controller that can provide active PFC for power systems up to 3kW in a wide variety of industrial applications.
Trench process slashes MOSFET on resistance
ON Semiconductor has developed a novel trench process technology that it claims on average delivers a 40% improvement in on-resistance when compared with other trench processes on the market today.
These devices are ideal for PCI Express, Gigabit Ethernet, and FBDIMM applications.
The PureEdge architecture provides increased design flexibility and reduces system cost compared with 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 0.25um 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 25MHz crystal with four selectable output frequencies and integrated 1:2 fanout buffer (NB3N5573).
The device provides phase noise of -130dBc/Hz relative to the carrier at 100kHz offset from the carrier frequency.
Like all ON Semiconductor PureEdge 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", says 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 PureEdge products that target the demanding technological needs and unique industry challenges of the marketplace".
Offered in 5.0 x 4.4mm lead free (Pb-free) TSSOP-16 packages, the NB3N3002 and NB3N5573 are budgetary priced at US $1.80 per unit in 2500-unit quantities.
