Using Calibration to Optimize Performance in Crucial Measurements
Texas Instruments Inc. (TI) introduced the industry’s fastest 4-channel, 14-bit analog-to-digital converter (ADC), clocking in at 250 MSPS. The high-density ADS4449 enables receiver systems to support up to 125 MHz of instantaneous bandwidth in extremely small forms, such as multiple input and multiple output (MIMO) base stations and munitions guidance, or in greater density applications, such as active electrically scanned array (AESA) and other phased-array radars. For more information and to purchase evaluation modules (EVMs), visit www.ti.com/ads4449-pr.
System designers are increasingly challenged to pack more antennas, and their requisite receive chains, into remote radio units and AESA radar systems, while also improving dynamic range and noise levels. The ADS4449 is the highest-performance 4-channel ADC at 250 MSPS, providing an additional 4-dB SNR and 8-dB SFDR, compared to existing 4-channel ADCs. By packing four 14-bit, 250-MSPS ADCs into a single package, the ADS4449 enables system designers to maintain small form factors and increase dynamic performance and signal bandwidth, while reducing power consumption and cost.
The ADS4449EVM is compatible with the TSW1400EVM data capture card and TSW1405EVM for pattern capture. For quick evaluation, TI also provides the HSDC-SEK-10 High-Speed Data Converter System Evaluation Kit for a low noise signal, clock and power source.
Support is available on the High Speed Data Converters Forum in the TI E2ETM Community, where engineers can ask questions and get answers from TI experts.
The ADS4449, ADS58H40 and ADS58H43 are available to order today in a 10-mm by 10-mm BGA package. Pricing is as follows in 1,000-unit quantities: ADS4449 for US$199.85; ADS58H40 for US$168.95 and ADS58H43 for US$139.13.
