SiTime Debuts Programmable Spread Spectrum Clock Oscillators

SiTime, a start-up based in Sunnyvale, California, introduced a new family of programmable spread spectrum clock oscillators based on MEMS resonator technology. The new devices offer the smallest footprint in the industry and the lowest cycle to cycle jitter. The devices are especially aimed at applications where system designers need to reduce electro-magnetic interference (EMI) in order to pass environmental testing standards. As a drop-in replacements for standard oscillators, the new MEMS-based devices can significantly lower EMI without the system designer needing to redesign the system board, adopt a metal enclosure for the product or implement other costly noise shielding changes to the design. SiTime said its new programmable spread spectrum clock oscillators are typically delivering an EMI reduction of 6-12 dB. The company also expects its MEMS technology to offer 10 times better robustness and reliability than existing, quartz-based solutions.

The SiT9001 is available in a standard footprint four-pad 2.5 x 2.0 mm package, the smallest in the industry for spread spectrum oscillators. The device also is available in larger, standard-footprint surface-mount packages that can replace existing oscillators without an expensive board redesign. The solution delivers a programmable frequency range of 1 MHz to 200 MHz and programmable operating voltages of 1.8V, 2.5V or 3.3V. Cycle to cycle jitter is rated at less than 30 ps.

The SiT9002 is optimized for high-performance networking and computing applications and offers low voltage differential signaling (LVDS), low voltage positive emitter coupled logic (LVPECL) and current mode logic (CML) outputs. The device is available in six pad, 5.0 x 3.2 mm and 7.0 x 5.0 mm packages, which are compatible with industry-standard footprints. The SiT9002 is programmable, with a frequency range from 10 MHz to 220 MHz and programmable operating voltages of 1.8V, 2.5V or 3.3V. It offers frequency tolerance of 25 PPM or 50 PPM when spread spectrum is turned off. And, like the SiT9001, the device delivers cycle to cycle jitter of less than 30 ps.
  • SiTime is headed by Rajesh Vashist (CEO), who previously served as CEO and chairman of the board at Ikanos Communications. SiTime's executive team also includes Aaron Partridge (who previously coordinated the MEMS resonator research at Robert Bosch Research and Technology Center in Palo Alto), Markus Lutz (also previously with Bosch), Fari Assaderaghi (previously with Rambus and HP), Narayanan Bharath (previously with Ikanos), and Piyush Sevalia (previously with Ikanos).

AudioCodes Announces High Definition VoIP Strategy

AudioCodes outlined a strategy to embed high definition VoIP capabilities across its product portfolio throughout 2009.
The company's "VoIPerfectHD" technology delivers higher voice clarity, better intelligibility and richer sound, as well as significantly improving a user's experience by doubling the audible voice spectrum.

AudioCodes VoIPerfectHD implementation of HD VoIP relies primarily on AudioCodes leadership in DSP, voice coding and voice processing technologies, and their application to VoIP communications and conferencing. AudioCodes VoIPerfectHD implementation as a unified infrastructure for all AudioCodes' products allows the offering of HD VoIP capabilities and benefits across all of its products ranging from Multi-Service Business Gateways (MSBG), Media Servers, Media Gateways and DSP chips to IP Phones. Applications include both enterprise and service provider networks.

AudioCodes' current and planned HD VoIP Enabled products consist of the IPmedia 3000 Media Server, Mediant 3000 Media Gateway, Mediant 1000 MSBG and the Mediant family of Microsoft certified basic Hybrid Gateways. AudioCodes' Media Servers and Gateways now enable transcoding between different wideband coders while retaining wideband quality. This will allow interworking and connectivity between different wideband networks such as mobile and broadband. AudioCodes plans to introduce HD VoIP on more products in 2009.

AudioCodes noted that over the past 10 years VoIP has succeeded in providing lower cost and greater flexibility on converged voice and data networks, but in general failed to deliver 'better-than-PSTN' quality mainly due to its 3.4 kHz bandwidth limitation connected with the use of legacy narrowband speech codecs in VoIP networks. With the advent and growing spread of IP broadband networks, wideband speech codecs which encode 7.1 kHz of the voice spectrum can now be effectively deployed to double the bandwidth and improve everyday voice communication quality to a level similar to that of conference room quality and/or FM radio. AudioCodes has been working over the past few years and increasingly in 2008 to implement a group of standards-based wideband speech codecs including G.722, AMR-WB, Microsoft RTAudio and others for use in wireline, wireless, cable, enterprise and internet applications with the goal of leading the transition towards increased use of HD VoIP in evolving voice communication networks.

"With our launch of VoIPerfectHD, AudioCodes is creating a whole new market opportunity for the company's voice communication business and introducing a key competitive differentiator in our markets. It's about bringing a new real sense of quality to VoIP communication, enabling improvements to business productivity and clear interpersonal communication between people and across wireline, wireless and cable IP networks," stated Shabtai Adlersberg, Chairman, President and Chief Executive Officer at AudioCodes. "AudioCodes' rich expertise in voice coding and transcoding enables us to offer enhanced connectivity between HD VoIP islands in disparate networks in broadband, IMS, Mobile and Cable, and offers greater flexibility in future interconnecting HD VoIP devices."

Motorola Demos Over-the-Air LTE Session in 700MHz Spectrum

Motorola has completed the first over-the-air Long-Term Evolution (LTE) data sessions in the 700MHz spectrum using its LTE Radio Access Test Network and LTE eNode-B platform with a prototype LTE device. The milestone was achieved in Motorola labs and at an outdoor location in central Illinois. The sessions included mobile video streaming and various high data rate applications. The demonstrations also included execution of applications priority which guarantees throughput using quality of service (QoS) aspects of the LTE standards.

Motorola noted that lower frequency bands provide better coverage and in-building penetration, which is a requirement for many mobile operators. In North America, the 700MHz spectrum auctioned earlier this year is part of the worldwide "digital dividend" - spectrum in the 470-862MHz bands that has been freed by the switch from analog to digital TV. The In Europe digital dividend spectrum encompasses the current TV broadcast 790-862MHz bands. It is expected to be auctioned between 2009-2012, coinciding with mobile operators' plans to deploy LTE.

"This field test shows the progress we've made in preparing to deliver a commercial LTE solution for testing and early limited deployments in 2009," said Darren McQueen, vice president, Wireless Broadband Access Technologies, Motorola Home & Networks Mobility. "We are testing our 700MHz and 2.6GHz products, which are expected for first commercial release next year, in real-world environments to ensure our products will meet the needs of mobile carriers who want to be first to market with LTE."
  • The FCC's 700 MHz auction held earlier this year raised a record $19.592 billion.

FCC Puts Off Vote on Intercarrier Compensation and Universal Service Reform

The FCC will not vote on Intercarrier Compensation and Universal Service reform at its scheduled meeting this week. The items had been on the agenda, but four out of the five commissioners said they were not prepared to vote on the issues at this time.

In a statement, FCC Chairman Kevin Martin said: "The issues of Intercarrier Compensation and Universal Service reform have been in front of the Commission for years. Last summer I publicly indicated my intention to put forward concrete and comprehensive proposals to reform the inefficient and outmoded Intercarrier compensation and Universal Service programs. Those proposals have been with my colleagues for several weeks now. I am disappointed that we will miss the opportunity for comprehensive reform. Instead my colleagues have requested that we once again seek public comment on several proposals. As a result such a notice would make little progress and ask for comment again on the most basic and broad questions about reforming the two programs. For example, the Commission would again ask should broadband be supported by the Universal Service Fund and should we move to one uniform rate for all traffic or should that rate vary by the type of company?

I would like to be encouraged by my colleagues' commitment that they will truly be ready to complete this much needed reform on December 18. The nature of the questions they would like to include makes me doubt they will have found their answers with an additional seven weeks. I believe the far more likely outcome is that, in December, the other Commissioners will merely want another Further Notice and another round of comment on the most difficult questions. I do not believe they will be prepared to address the most challenging issues and that the Commission will be negotiating over what further questions to ask in December."

In response, the four other FCC Commissioners issued the following joint statement:

""Three weeks ago, Chairman Martin first shared with the Commission his proposals to fundamentally reform the intercarrier compensation and universal service systems. Four Commissioners provided the Chairman bi-partisan, constructive and substantive suggestions, and stated that notice and comment should be sought on the proposals, with an understanding
that we would all be prepared to vote on December 18. We also have asked the Chairman to narrowly address the ISP-bound traffic remand and the Joint Board's Recommendation. We therefore are disappointed that the Chairman has withdrawn the fundamental reform item from tomorrow's agenda.

"We approached this proceeding with the common goal of modernizing our universal service and intercarrier compensation policies, and commend the desire to tackle some of the most important issues facing this Commission. It is equally important to ensure that any reform proposal receive the full benefit of public notice and comment - especially in light of the difficult economic circumstances currently facing our nation.

"We remain committed to fulfilling our obligation to tackle these difficult issues, and have set forth a reasonable path for completing comprehensive reform. We remain hopeful that the consensus process we have pursued regarding this issue will ultimately lead to a thoughtful, well-reasoned item that will inure to the benefit all Americans."
