Press Release Summary:
Series ADS6000 is comprised of 2- and 4-channel, 12- and 14-bit ADCs offering speeds of 80, 105, and 125 MS/sec. Integration of single- or dual-stream serialized LVDS outputs optimizes board space, and LVDS output can be optimized by adjusting driver currents and internal termination resistors. Through SPI interface, products provide programmable options such as coarse and fine gain controls. Model ADS6425 offers 70.3 dB SNR and 83 dB SFDR at 50 MHz IF.
Original Press Release:
TI Advances Communications, Imaging and Instrumentation with Industry's Highest-Performance Dual and Quad ADC Family
DALLAS (April 16, 2007) - Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a new family of two- and four-channel 12- and 14-bit analog-to-digital converters (ADCs) featuring high speed, low power and high performance housed in tiny 9-mm x 9-mm packages. This pin-compatible family offers designers an easy upgrade path with a range of resolutions, speed and performance options tailored to meet the requirements of advanced communications, radar and imaging, test and measurement, medical, and video applications. See www.ti.com/ads6425-pr.
"Today's high-speed applications are demanding greater system density and performance while still providing low power consumption. Texas Instruments' ADS6000 family delivers on these demands with pin-compatible, multi-channel ADCs that combine exceptional speed, performance, size and power," said Art George, senior vice president of TI's high-performance analog business unit. "By offering world-class support and tools for this leading technology, TI is enabling customers to realize new capabilities in applications that require multiple ADCs at high speeds."
The ADS6000 family consists of dual and quad, 12- and 14-bit ADCs available in speeds of 80, 105 and 125 MSPS. Each device in the family delivers exceptional spurious-free dynamic range (SFDR), high signal-to-noise ratio (SNR), high IF capability and low power per channel. By incorporating single- or dual-stream serialized LVDS outputs, the devices reduce board space by 60 percent compared to CMOS output solutions.
Through an SPI interface, the ADS6000 family provides programmable options such as coarse and fine gain controls to trade a small amount of SNR for a significant increase in SFDR at high IFs, enabling the customer to tailor the performance to the specific application requirements. Designers are also able to optimize the LVDS output configurations by adjusting the driver currents and internal termination resistors to reduce power consumption, improve signal integrity and ease data capture.
The quad, 12-bit, 125-MSPS ADS6425 is the first in this family of products and provides high performance at 70.3 dB SNR and 83dB SFDR at 50MHz IF in the nominal state, with the ability to reach 86 dB SFDR through gain settings. The 14-bit, 125-MSPS ADS6445 provides an upgrade path for customers requiring higher resolution. Consuming only 410 mW or 420 mW per channel at 125 MSPS, the ADS6425 and ADS6445 allow higher system integration and greater flexibility as well as many other system benefits including:
· Enhanced resolution for object tracking and discrimination in radar systems
· High sample rate and resolution for increased bandwidth and advanced medical imaging capability
· Higher performance, smaller form factor and extended battery life for portable test equipment
· Improved sensitivity and reduced bill-of-materials for diversity receivers in wireless infrastructure
· Increased density and sample rate for smaller form factors in high-end video equipment
Easy-to-use evaluation modules (EVMs) and deserializer cards available from TI provide quick and cost-effective evaluation to help customers speed the design process for quicker market penetration. To further simplify design, TI offers a wide variety of parts to complete the signal chain. High-speed, low-noise amplifiers, such as the THS9001 and THS4509, allow the ADS6425 to operate to its full input bandwidth. The CDCM7005 low-skew clock synchronizer provides low-jitter clocking to maximize SNR performance. For parallel transmission paths, TI can provide multi-channel digital-to-analog converters and digital up/down converters such as the DAC5672 and GC5016. Customers may also utilize TI's broad portfolio of high-performance and optimized TMS320(TM) DSPs for these applications.
