SAN FRANCISO—Broadcom Corp. has introduced a pair of system-on-chip (SoC) devices for the U.S. digital television (DTV) market that include multi-format decoding, Ethernet network connectivity, a 3D graphical user interface, and 3D color management.

The combination of 19-slot capacity, cooling design, 0 to 55°C operating temperature rating, and the chassis management features makes the PXIS-2719 an suited platform for variety of PXI system controllers, instrument boards, data acquisition modules, and I/O boards for a wide range of PXI applications.

COLORADO SPRINGS, Colo. — Having scored another important win for its Gobi broadband wireless access technology through a deal with Dell Computer, Qualcomm Inc. said Panasonic also has agreed to use Gobi in at least three families of Toughbook ruggedized notebooks, and will continue to evaluate follow-on versions of Gobi that add WiMax or Long-Term Evolution support.

The Gobi broadband access chip set currently supports EV-DO and HSPA networks, and has added firmware to support HSPA+ and Global Positioning System capabilities. Victoria Obenshain, director of wireless strategy at Panasonic, said one reason for beginning rollouts with the fully ruggedized CF series, which will offer Gobi this fall, is that first-responder users of the fully ruggedized version are those that are most likely to have to contend with multiple networks.

This will migrate to the business community at large, but we could see that police and fire in emergencies, as well as the military, were the ones most likely to need multiple services,” she added.

Mike Concannon, senior vice president of product management for Qualcomm's CDMA Technologies unit, said Gobi capabilities represent the emergence of software-defined radio (SDR) features in laptops. With special Carrier Selection Application software Panasonic is bundling with the Toughbook, SDR features become virtually transparent to users, he predicted.

Previously, Obenshain said, Panasonic relied on single-air interface modules from vendors such as Sierra Wireless and Novatel to support a single packet-data wireless standard. Gobi represents the first time the company will support multiple networks with a single chip set and a unified software development kit. Concannon said Qualcomm does not see Sierra Wireless or Novatel as competitors; in fact, several module specialists are interested in integrating Gobi into single-card communication modules for after-market notebook sales.

Obenshain said Panasonic is considering several ways to use the GPS services within Gobi ” and not just in traditional location-based services, but in tracking lost or stolen laptops and in developing time-stamp functions.

The Toughbook line is designed not just for rugged use, but with multiple layers of security for government and highly-secure enterprise applications. The CF-19 and CF-30 Toughbooks with Gobi will debut in October. Enterprise level Business Rugged platforms, weighing 4.5 pounds, will debut in November. The U-1 Ultra-Mobile Rugged system with Gobi will launch in the first quarter of 2009.

The GB20600-2006 standard was formerly known as DMB-T/H (Digital Multimedia Broadcasting Terrestrial/Handheld).

Some observers call China's GB20600 standard an ultimate compromise” of two competing standards — one developed by Tsinghua University in Beijing and another by Jiaotong University in Shanghai. The new spec is viewed as the co-existence of two separate standards, rather than a single standard integrating both approaches.

Tsinghua's system TDS-OFDM (Time Domain Synchronous OFDM) uses multicarriers just like DVB-T and Japan's ISDB-T. Meanwhile, Jiatong's ADTB-T (Advanced Digital Television Broadcast Terrestrial) is a single carrier vestigial sideband system based on the US 8-VSB standard.

Legend Silicon, with strong ties to Tsinghua University, provided the brains behind TDS-OFDM development.

Legend Silicon noted that the new chips are the company's 8th generation DTV demodulator compliant to China's terrestrial DTV standard.
