Analog-to-digital converter provides twice the sample rate for wireless communications, defense, and test and measurement equipment
"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). The BiCom3 technology's silicon-on-insulator (SOI) process makes it well suited for high-temperature and high-radiation environments.
Key features and benefits
-- Fully buffered, 12-bit, 1-GSPS ADC with 2.1 GHz input bandwidth, for wideband signals in oversampling and undersampling applications with 200 MHz or greater signal bandwidth -- Buffered analog input provides constant input impedance across time and frequency and eliminates sample-and-hold kickback, simplifying input matching for passive and active analog front end -- The ADS5400's adjustable fine gain, offset and phase ease the interleaving of two or more ADCs to create a multi-GSPS digitizer, or the balancing of two ADCs in an I/Q receiver -- Thermally-enhanced, 100-pin TQFP (16 mm x 16 mm footprint) package with exposed thermal pad -- User-selectable single- or dual-bus DDR LVDS outputs provide designers flexibility to choose between I/O speed and pin-count -- Customers can speed time-to-market with compatible TI devices: THS9000 and THS9001 amplifiers to support input frequencies up to 500 MHz; the CDCE72010 high-performance, low phase noise, and low skew clock; the DAC5682Z dual, 16-bit, 1 GSPS DAC; the TPS727xx and TPS717xx low dropout regulators; and the TMS320C6474 and TMS320C6457 DSPs.
Availability and pricing
The ADS5400 is available now in a 100-pin TQFP package and is priced at $775 in 100-unit quantities. An EVM is available for $1299 and is compatible to TI's TSW1200EVM digital capture card, offering a flexible evaluation environment for ADC analysis.
