250 MPS datakonverter slår rekorder
Texas Instruments lancerer 250 MSPS datakonverter med 66 procent højere båndbredde end eksisterende dual A/D-konvertere (in english).
Texas Instruments (TI) has introduced a dual, 14-bit analog-to-digital converter (ADC) at 250 MSPS (mega samples per second) to deliver a premier combination of wide signal bandwidth, high dynamic performance and low power consumption.
The ADS62P49 achieves 73-dBFS signal-to-noise ratio (SNR) and 85-dBc spurious-free dynamic range (SFDR) at an input frequency of 60 MHz. With the industry’s fastest sample rate, the ADS62P49 provides increased signal bandwidth without compromising range and sensitivity in communications and defense imaging systems or accuracy in wide-band test and measurement equipment.
- Communications, defense and test design engineers are constantly challenged to create signal and data acquisition receivers with increasingly wide signal bandwidths that do not compromise overall system performance, says Art George, senior vice president of TI’s High-Performance Analog business unit.
- TI addresses these challenges with the ADS62P49 which delivers high-performance, compact, power-efficient designs and enables rapid deployment of 3G and 4G systems, software defined radios and spectrum analyzers.
The ADS62P49 is available today in a 9 mm x 9mm QFN package for $144.75 in 1,000-piece quantities. The ADS62P49EVM has on-board sockets for a voltage-controlled crystal oscillator, crystal filter and TI’s newest high-performance clock distribution and jitter cleaning chip, the CDCE72010, which allows the EVM to function as a system-level evaluation kit and an ADC evaluation board.
Customers can also leverage TI’s TSW1200 digital capture tool for rapid evaluation of LVDS-output ADCs of up to 16-bit resolution and 500-MSPS sample rates to enable prototyping of complex systems and to further speed development time.
