2/12/2004 - Enhancing its already broad portfolio of analog and digital signal processing products for wireless infrastructure base station manufacturers, Texas Instruments (TI) (NYSE: TXN) is featuring several new devices spanning the signal chain from the antenna to the network. These products are expected to dramatically enhance infrastructure systems, ultimately enabling cellular phone users to receive voice and data calls in more ways and with better service. When combined with TI´s existing solutions, these new products will improve system efficiency by up to 30%, while lowering the total cost of ownership.
According to industry analyst firm Forward Concepts, global subscriber numbers expanded by 15.5%, and "minutes of use" grew 26% in '03. Data intensive applications, such as emailing 2-3 megapixel images captured by camera phones, are expected to place a greater burden on the already strapped wireless infrastructure. Combined, these factors are spurring system providers toward cost effective, flexible and complete solutions that help minimize capital and operating expenditures.
Leveraging its significant experience with wireless infrastructure customers, TI has responded to these market factors by developing high performance products which provide greater channel density, increased system flexibility and enable customers to get to market faster.
"TI is in the sweet spot of a wireless infrastructure market that is approaching a crucial time in its history," said Jerold Givens, manager of TI's wireless infrastructure DSP group. "We continue to translate our increasing system knowledge into the right products that will enable networks to deliver feature-rich services consumers want."
Subhead: TI Spans the System from Antennae to Network
TI's digital signal processor (DSP) optimized for wireless infrastructure - TMS320TCI100 - is now available in 720 MHz at the 90 nanometer process node. Along with an extremely power efficient core (~600mW), this device also supports integrated Viterbi and Turbo coprocessors, supporting over 600 voice channels (7.95 Kbps AMR) and 35 data channels (384 Kbps) respectively. When combined with the TCI110 and 120 receive and transmit accelerators, this device provides an optimized solution for WCDMA. In addition to the performance improvements this device brings to 3G base stations, it also handles all baseband processing for two GSM/EDGE carriers, with ample overhead. A complete set of tools and software are also available, reducing the infrastructure network manufacturer's total cost of ownership while accelerating time to market.
Combining the optimized TMS320TCI100 solution with TI's high density, field hardened voice over packet (VoP) gateway solutions address the tough challenges facing service providers deploying packet-based networks. Designed with an emphasis on solution density, they address solution architecture, channel density, power per channel, and carrier class features to deliver a complete solution. This high performance solution increases the number of GSM Adaptive Multi Rate (AMR) speech coding channels to 41 - offering improvements over the previous solutions.
TI also provides customers the capability to develop a true system on a chip using state-of-the-art ASIC manufacturing process and highly differentiated intellectual property, including, high speed serial links and several DSP cores.
Broadest Analog Portfolio Accelerates Time to Market, Reduces Cost of Ownership
The 14 bit, 125 MSPS ADS5500 analog to digital converter and the 16 bit, 500 MSPS DAC5686 are only two of the latest high performance additions which have been made to the robust portfolio of analog products from TI. The ADS5500 delivers breakthrough receiver performance - SNR of 70 dB and SFDR of 82 dB at 100 MHz IF - at the lowest power. This allows accurate reception of weaker, distant signals, up to 190 MHz. As a result, base stations can process multiple carriers in a single radio chain, reducing the total system cost and number of analog components.
"With the additions of our recent high performance analog products, TI is strongly positioning itself to offer one-stop shopping for the entire transceiver card - data converters, up/down converters, SerDes devices, connectivity, clocking, logic and power management," said Kent Novak, manager for TI's analog wireless infrastructure business unit. "In addition, we will be enhancing this broad portfolio with several RF products in the first half of this year, giving customers even greater choices for both high performance and low cost systems."
As a dual data converter, the DAC5686 provides superior ACPR performance at high IF while providing customers with flexible, programmable options using three modes of operation and integrated digital functions. It supports up to four WCDMA or CDMA2000 carriers and requires 50% less power than competitive products.
The programmable digital down or up converter, GC5016, accepts inputs from ADS5500 in receive mode or provides output data to the DAC5686 in transmit mode. It can also be used in transceiver mode to provide single chip digital down converter and digital up converter functionality for single carrier applications such as pico cell base stations and repeaters.
Debuting this quarter will be the GC5316 targeting higher density, multi-carrier applications. This new down/up converter handles up to 24 CDMA2000 or 12 WCDMA channels. It can also be configured to support mixed standard operations such as CDMA2000 and WCDMA using a single chip. The device is expected to be released to production in 2Q04.
Completing the signal chain for the transceiver card is a family of operational amplifiers including the THS4271 high-speed operational amplifier, which delivers ultra-low distortion with ultra-low noise. Several timing devices are also available, including the CDC7005, TI's new low phase noise clock synthesizer, which provides multiplying, dividing and jitter cleaning for optimal timing performance. TI will also be releasing to production a family of high performance RF products which are targeted at infrastructure systems.
TI's TLK family of serializer/deserializer devices support data rates from 500 Mbps to 2.5 Gbps with low power dissipation and built-in high-speed equalization which allows for greater signal integrity in long links. With its advanced CMOS technology and expertise in high-speed serial and parallel I/O, this technology gives customers the ability to increase the port density of existing systems without having to replace legacy backplanes. Also, TI recently announced a 6.25 Gbps serial link capability that provides customers an upgrade path to 6 Gbps transmission over legacy system backplanes.
While much of the base station manufacturer's focus is on the core components of the signal chain, flexible, high performance supporting products can provide significant improvements in system efficiency. As the leader in logic, TI applies its CMOS technology to the AUP and AUC low power and high speed families ideal for wireless applications. Also available are both high-drive (100 mA) GTLP devices for heavily loaded backplanes as well as medium drive devices (50 mA). The CBT, CB3Q, CB3T and CBTLV families of Bus Switches offer designers a broad portfolio to meet their switching needs.
TI offers a broad range of power management products - both discrete and modular, - targeting wireless infrastructure applications. Our market-proven record of expertise has made TI's power technology very easy to use for designers thus lowering overall development time.
