Phoenix, Ariz. — ON Semiconductor has expanded its high-performance clock and data management portfolio with the introduction of nine PureEdge PLL-based clock modules for crystal oscillator (XO) replacement. Marking the company's entry into the frequency control market, the NBXxxxx series is suitable for high-speed networking, telecom, and high-end computing applications.

The silicon-based crystal oscillator modules — the NBXSBA010, NBXDBA012, NBXDBA014, NBXDBA015, NBXDDA016, NBXDBA017, NBXDBA018, NBXSBA020 and NBXSBA021 — use a high Q fundamental mode crystal and analog phase lock loop (PLL) multiplier to provide single or dual frequency, ultra-low jitter and a phase noise LVPECL/CML differential output.

Delivering ultra-low jitter and phase noise, the NBXSxxx (single frequency)/NBXDxxx (dual frequency) family of crystal oscillators are said to offer the industry's best long-term time domain jitter performance and excellent device noise floor of -163 dBc/Hz at 10-MHz offset with phase RMS jitter of 0.4 picoseconds (ps) (12 Hz to 20 MHz).

These sub-picosecond jitter quality clocks deliver single and/or dual frequency of 100 MHz, 106.25 MHz, 125 MHz, 155.52 MHz, 156.25 MHz, 200.00 MHz, 212.5 MHz, 250 MHz, 311.04 MHz and 312.5 MHz that are well-suited for 1x/2x FibreChannel, SATA, iSCSI, PCIe, SONET/SDH, Ethernet and clock margining applications. The devices are available in a 5.0 x 7.0-mm SMD (CLCC-6) package.

Pricing: The NBXSxxx (single frequency) and NBXDxxx (dual frequency) devices are budgetary priced at $5.99 for +/-50 ppm devices and $7.50 for +/-20 ppm each in quantities of 1,000.Product information: NBXSxxx and NBXDxxx devices

Grau Elektronik has developed a converter family for railway system voltages of 72 and 110 V ± 40 percent. Output power is 750 or 1000 W. The standard output voltage is 24 V. Other higher output voltages are also available on request. The operating temperature range is -40 to + 85 °C, class Tx EN 50155. The converters are available in IP 20 housing for wall mounting. Efficiency is 85 to 88 percent. The converters are no load and short circuit proofed. A Power Fail signal pin (open collector transistor) is provided for signaling overload conditions. The converters fullfill railway standards EN 50121-3-2, EN 50155, …

The company has also developed a new converter family for wall mounting with input voltage ranges of 14.4 to 50.4 V and 43.2 to 154 V at EN 50155. Their operating temperature range is -40 to + 70 °C. The converters have 10 ms hold up time compensating battery interrupts.

Recently, Texas Instruments signed an agreement with the Indian Institute of Technology-Kharagpur's School of Medical Science and Technology to develop semiconductor technologies for lower-cost medical electronics. The deal–the first of its kind with an Indian research institute–is part of TI's global initiative to invest $15 million to fund research in medical technologies at selected universities around the world.

At the TI Developer Conference, Rich Templeton, TI's president and CEO, laid out the financial incentives for following the medical market. Fifteen percent of the [U.S.] GDP in 2007 was spent on health care,” he said. Five percent [of that] was spent in China–and that's growing.”

Here, we present another viewpoint on the global growth of medical electronics.

Globalization has radically altered the business model for the service and manufacturing industries. Now health care, traditionally regarded as a local industry, is undergoing a similar transformation. The trend is changing how the Chinese think about financing hospitals, Americans recruit physicians, Australians reimburse care providers, Europeans embrace competition and Middle Eastern governments build for future generations.

There is growing evidence that the health systems of many nations are challenged by a confluence of trends: in- creasing demand, rising costs, uneven quality and misaligned incentives. New solutions are emerging from beyond traditional boundaries, and innovative business models are being formed as health care becomes globalized. Skyrocketing costs, reports of medical errors, consumer demand for better care and the need to move away from paper charts are all leading to a restructuring of health systems.
