(NYSE:TXN)

DALLAS, Oct. 26 /PRNewswire/ -- Texas Instruments introduced today an analog-to-digital-converter (ADC) that combines 12 bits of resolution with a 1-GSPS sampling rate, effectively doubling the amount of signal bandwidth that can be captured in a single ADC. The ADS5400 offers an unmatched signal-to-noise ratio (SNR) of 59 dBFS and 75 dBc spurious-free dynamic range (SFDR) in first Nyquist, and 58 dBFS SNR and 70 dBc SFDR performance for intermediate frequencies (IFs) beyond 1000 MHz. A fully buffered analog input isolates the onboard sample and hold's internal switching to prevent disturbing the signal source, while providing a high-impedance input. The ADS5400's performance enables designers to create smaller, higher-performance and higher-density wide-bandwidth receivers and digitizers. For product details see www.ti.com/ads5400-pr

"The ADS5400 has enabled our latest modular component, the QuiXilica Atlas-V5 VXS board, to handle 12 GB/s of data and generate a real-time result," comments Andrew Reddig, Tekmicro's president and chief technology officer. "Our launch customers are using the Atlas to create higher performance solutions for critical applications that were unachievable with previous A/D technology."

"Customers can use the ADS5400's ground-breaking combination of resolution, sample rate and bandwidth to significantly enhance applications in defense by improving radar and signal intelligence (SIGINT) capabilities, and can double the capture bandwidth of signals with 12-bit resolution in test and measurement," said Art George, senior vice president of TI's High-Performance Analog business unit.

Developed on TI's high-speed, proprietary BiCom3( )complementary bipolar SiGe technology, the monolithic ADS5400 is specified over the full industrial temperature range (-40 degrees C to 85 degrees C).

NewsCenter — Mon, 13 Oct 2008 08:00:00 GMT

New ADCs offer industry's highest dynamic performance while saving power in communications, defense, and test and measurement equipment

DALLAS (Oct. 13, 2008) - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced six 12- and 14-bit analog-to-digital converters (ADCs) with sampling rates as high as 250 MSPS (mega samples per second) to deliver a premium combination of wide signal bandwidth, high dynamic performance and low power consumption, enabling more efficient power amplifier linearization in digital pre-distortion (DPD) solutions, better range and sensitivity in radar and defense electronics and greater accuracy in high-speed test and measurement equipment. (For more information, see www.ti.com/ads6149-pr.)

With 14-bit performance, the ADS6149 is the highest resolution 250-MSPS ADC in production, providing designers with maximum performance along with low power consumption. The ADS6149 and buffered input ADS61B49 offer the industry's highest dynamic performance at 250 MSPS with greater than 70 dB signal-to-noise ratio (SNR) and 80 dB spurious-free dynamic range (SFDR) for input frequencies ranging from DC to 250 MHz. At the maximum sample rate of 250 MSPS, the ADS6149 consumes only 687 milliwatts (mW). At a sample rate of 150 MSPS, with dynamic power scaling, the device consumes as little 490 mW.

"The device's low power consumption allows our new generation of wireless and radar receivers to realize high channel density with high performance. This translates into reduced system cost and enables new applications that require tight integration of multiple channels with signal processing on a single card," said Dan McLane, co-founder of Innovative Integration.

The complete ADS61xx family of devices is highly flexible, which makes it easier for designers to maximize performance for their specific application. A 1- to 6-dB programmable gain option allows customers to optimize SNR, SFDR and input swing based on the unique needs of their application. For instance, designers can maximize SNR to enhance linearization effectiveness in DPD solutions, while SFDR can be increased and input drive reduced to improve small-signal analysis in defense and radio receiver applications. To further enhance flexibility, the ADS61B49 and ADS61B29 ease analog front end design by incorporating a fully differential input buffer. This buffer provides constant input impedance over input frequency and eliminates kickback from the ADC's track-and-hold circuit to ensure consistent linearity of the signal. And to provide a flexible digital interface, the ADS61xx family of devices features user-selectable parallel CMOS or differential double data rate (DDR) LVDS output options.

NewsCenter — Wed, 03 Sep 2008 08:00:00 GMT

Board enables rapid evaluation and prototyping of interleaved system for wide-bandwidth communications, military and test applications

DALLAS (Sept. 3, 2008) - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced an evaluation module (EVM) that combines TI's fastest 14-bit analog-to-digital converters (ADCs) in an interleaved fashion with a Xilinx&#174 Virtex&#174-5 FPGA to create the best-performing high-speed digitizer solution in the market. The FPGA comes pre-installed with SP Devices' proprietary time-interleaving technology to eliminate interleaving spurs, which enhances performance and facilitates rapid system-level evaluation for wireless communications, military, test and measurement applications. The EVM joins TI's portfolio of support tools for customers using high-speed data converters in wide-bandwidth applications. (See www.ti.com/ads5474adx-evm-pr.)

The ADS5474ADX-EVM incorporates two of TI's ADS5474 ADCs, a Xilinx Virtex-5 FPGA and SP Devices' proprietary time-interleaving technology to deliver an 800-MSPS ADC solution. The SP Devices' software continuously monitors the system and removes ADC gain, clocking and temperature mismatches to reduce the interleaving spurs below the ADC harmonic spurs. By reducing the interleaving spurs, the software increases spurious free dynamic range (SFDR) from 45.78 dBc to 86.44 dBc for a 70-MHz input signal.

"Addressing the industry's ever-increasing demand for higher sampling speeds and extended bandwidth is important to us," said Jonas Nilsson, CEO of SP Devices. "Combining SP Devices' innovative interleaving technology with TI's market-leading data converters allows us to extend performance boundaries of high-speed ADCs, which will enable exciting new applications including multi-carrier systems, software-defined radio, advanced imaging and beyond."

In addition to improved performance for these complex systems, the EVM simplifies evaluation and helps designers bring end systems to market faster.

NewsCenter — Mon, 23 Jun 2008 08:00:00 GMT

Solution delivers highest SNR and SFDR for demanding communications, defense, and test and measurement applications

DALLAS (June 23, 2008) - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a 16-bit, single-channel, 135 mega samples per second (MSPS) analog-to-digital converter (ADC) and a low-jitter clock synthesizer. The combined signal chain solution provides unmatched dynamic system-level performance in communications, defense, and test and measurement applications. The data converter and clock are available on the same evaluation module (EVM) to facilitate fast evaluations of these complex systems. (See www.ti.com/ads5483-pr.)

Low noise enhances performance in wide-bandwidth applications

The ADS5483 ADC has the industry's highest signal-to-noise ratio (SNR) and spurious free dynamic range (SFDR) over comparable ADCs on the market, for input frequencies from DC through the second Nyquist zone. Sampling at 135 MSPS, the ADC can achieve a SNR of 78.6 dBFS with 95 dBc SFDR for a 70-MHz input frequency (IF), which is up to 3.5 dB greater SNR or 8 dB greater SFDR over comparable ADCs. The higher performance of the ADS5483 increases design flexibility and benefits many applications. For example, it offers greater accuracy for test and measurement systems and higher sensitivity with larger bandwidths in wireless communication including air interfaces, such as WCDMA, TD-SCDMA, WiMAX, LTE and multi-carrier 3GSM.

In wide-bandwidth applications, the ADS5483 eases analog front-end design by incorporating a fully differential input buffer, a common feature across TI's family of ADS54xx ADCs. Developed in TI's BiCom3 high-speed process technology, this buffer provides constant input impedance over input frequency and eliminates kickback from the ADC's track-and-hold structure to ensure consistent linearity of the signal. In addition, unlike competitive ADCs, the ADS5483 utilizes differential double data rate (DDR) LVDS outputs to significantly reduce the number of I/O traces and pins it consumes on FPGA or ASIC devices.

Highly flexible clock enables system-level performance

The ultra-low jitter CDCE72010 clock synthesizer provides best-in-class additive jitter performance at less than 50 femtoseconds (fs), which meets the jitter requirements to clock high-speed ADCs, such as the ADS5483. For example, the combined EVM using the CDCE72010 and a crystal band pass filter to drive the ADS5483 at 122.8 MSPS achieves a high system-level SNR of 78.0 dBFS SNR and 89.1 dBc SFDR with a 100-MHz input frequency.

The new clock synthesizer can accommodate a wide range of frequencies to meet the requirements of various systems, such as wireless base stations or test and measurement equipment. It can support up to 10 LVPECL, 10 LVDS or 20 LVCMOS configurable outputs at frequencies up to 1.5 GHz and input frequencies from 8 KHz up to 500 MHz. Designers can integrate two frequency sets within one clock synthesizer with the option of two external VCO/VCXOs. The CDCE72010's on-chip EEPROM stores default settings, which allows designers to reduce system start-up time and eliminates the need for an external component.

Tools and signal chain solutions ease development and enable rapid evaluation

The ADS5483 and the CDCE72010 are available on the same EVM to facilitate fast evaluations of complex systems. To provide designers with frequency planning flexibility, the EVM includes an open socket for the VCXO and crystal filter as well as bypass for an external source clock input. TI also offers the TSW1200 digital capture tool, available across a wide portfolio of TI's high-speed LVDS-output ADCs. The TSW1200 enables rapid evaluation for ADCs of up to 16-bit resolution and 500-MSPS sample rates to simplify design and help designers bring systems to market faster.

To further ease design and speed time-to-market, TI offers a wide variety of devices to complete the signal chain, including those listed below.

Availability and packaging

The ADS5483 and CDCE72010 are both available today in QFN-64 PowerPAD packages. Pricing in quantities of 1,000 is $65.00 for the ADS5483 and $10.95 for the CDCE72010. Samples, EVMs and the TSW1200 capture card for a rapid and cost-effective evaluation are available from www.ti.com/ads5483 and www.ti.com/cdce72010.

It includes an on-chip 4.096V reference and a flexible voltage serial interface that can operate down to 1.65V I/O for glueless connectivity to any TI DSP processor. In addition, the device operates from a single 5V analog supply. The ADS8519 is able to deliver outstanding DC performance with only 0.05 percent full scale range (FSR) gain error and 2mV of bipolar zero error while still keeping power dissipation low at only 100mW for the full 250kHz sampling rate. This combination of features and performance makes it an attractive option for new +/-10V industrial designs.

The ADS8513 is a drop-in upgrade to the ADS7813 and provides improved performance for current products without costly board redesigns. It offers excellent DC performance of +/-2 LSB maximum INL and -1/+2 LSB maximum DNL. In addition, its exceptional AC performance, including a high signal-to-noise ratio of 89dB, low total harmonic distortion of 100dB and spurious-free dynamic range of 102dB, provides improved accuracy for high dynamic range signals. The device has full scale error drift of 0.2ppm/C and bipolar zero error drift of 2.5ppm/C. With its single 5V supply, the ADS8513 uses only 24mW at 40kSPS.

TI introduces 4- and 8-channel, simultaneous sampling, 16-bit ADCs for precision signal acquisition

NewsCenter — Fri, 23 May 2008 07:00:00 GMT

DALLAS (May 23, 2008) - Texas Instruments Incorporated (TI) (NYSE: TXN) today announced two multi-channel, 16-bit, delta-sigma analog-to-digital converters (ADCs), which combine outstanding DC accuracy and AC performance with cost-effective integration. The ADS1174 (4-channel) and ADS1178 (8-channel) provide a simultaneous-sampling measurement system for demanding signal acquisition applications, such as power metering, defibrillators and ECG monitors, as well as pressure sensors, coriolis flow meters and vibration/modal analysis. (See www.ti.com/ads1174-pr.)

The ADS1174 and ADS1178 feature 25kHz bandwidth, 2uV/C offset drift and up to 97dB signal-to-noise ratio (SNR). Two operating modes allow for optimization of speed (52kSPS) or power dissipation (7mW/channel).
Traditionally, industrial delta-sigma ADCs offering good drift performance use digital filters with large passband droop, resulting in limited signal bandwidth and mostly suited for DC measurements. High-resolution ADCs for audio applications offer larger usable bandwidths, but the offset and drift specifications are significantly worse (and often unspecified) than their industrial counterparts. The ADS1174 and ADS1178 combine these two types of converters, allowing high-precision industrial measurements with excellent DC and AC specifications.
The high-order, chopper-stabilized modulator achieves very low drift and low noise over the signal bandwidth of DC up to the Nyquist frequency. The onboard decimation filter suppresses modulator and out-of-band noise, providing a usable signal bandwidth up to 90 percent of the Nyquist rate with stopband attenuation of 100dB.
A selectable SPI or frame sync serial interface allows for convenient interfacing to DSPs, FPGAs and microcontrollers. Either interface supports daisy chaining to simplify readback of multiple ADS1174 or ADS1178 ADCs in high channel-count systems. The ADCs are fully specified over the industrial temperature range of -40C to +105C. Available in identical packages, the ADCs are drop-in compatible with the high-performance, 24-bit ADS1274 and ADS1278 for convenient upgrades.

Availability

The ADS1174 and ADS1178 are available now in HTQFP-64 PowerPAD^TM packages. The ADS1174 is priced at $12.45 each in 100-piece quantities (suggested resale pricing). The ADS1178 is priced at $19.95 each in 100-piece quantities (suggested resale pricing).
