26-Dec-00

NxtWave Communications Inc., (www.nxtwavecomm.com) a developer of broadband communications integrated circuits (ICs), introduced the NXT2002, its second-generation multimode VSB/QAM receiver chip for digital televisions (DTVs), PCs and digital set-top boxes. Compliant with the North American ATSC standard for broadcast, NXT2002 decodes both vestigial side-band (VSB) for terrestrial broadcast and in 64 or 256 quadrature amplitude modulation (QAM) modes for DTV cable connections and DTV Interactive reception. ""The NXT2002 is testimony to NxtWave's commitment to the DTV industry,"" said Matt Miller, President and CEO of NxtWave Communications Inc. ""With our unique combination of market focus and innovative technology, NxtWave continues to drive the advancement of the industry with improvements to VSB design and performance.""The NXT2002 combines best-in-breed performance and an extensive user-friendly feature set in the smallest package on the market today. The device demonstrates superior reception performance in the presence of multipath, phase noise, impulse noise, adjacent and co-channel interference for both terrestrial and cable environments. ""The ATSC is delighted to learn of the introduction of NxtWave's second-generation high-performance VSB receiver chip. NxtWave's latest technical advancements exemplify the kind of innovation manufacturers are making in ATSC integrated circuits and receivers,"" said Robert Graves, Chairman of the Advanced Television Systems Committee (ATSC). ""Such improvements and industry support will help to accelerate the transition to digital television.""""DTV and HDTV are rapidly gaining market momentum. Technological innovations, such as the NXT2002 receiver chip, are critical elements of the consumer electronics industry, which constantly strives to give consumers ever-improving value in their products,"" said Gary Shapiro, President and CEO of the Consumer Electronics Association (CEA). ""New product introductions are always important in developing a new category, like DTV, to marketplace success.""The NXT2002 is the only VSB/QAM receiver chip to offer the rejection of 0dB echoes. The advanced sparsed equalizer provides better AWGN performance, enhanced multipath tracking and less jitter than conventional equalizers, producing a more reliable architecture that enables and maintains signal lock for continuous picture feed. New developments in NXT2002's integrated adaptive control allow for reliable acquisition and reacquisition of DTV signals, resulting in clear high definition reception for consumers.Configurable to operate from a 25MHz crystal or from an external 25MHz clock source, the on-chip integration of the direct IF sampling 10-bit ADC, AGC integrator, tuner control, all-digital symbol recovery and the all-digital carrier recovery circuitry further reduces the cost of external components for DTV manufacturers.Packaged in a 100-pin thin quad flat pack (TQFP), the price of the NXT2002 is $20 each in 10,000-unit quantities. Production quantities are scheduled for first quarter of 2001. For more information about NxtWave Communications Inc., visit www.nxtwavecomm.com.
