Analog Devices, Inc.
(ADI), the leading provider of data-conversion technology* and longtime collaborator with the medical imaging industry, today introduced the industry’s first octal ultrasound receiver to feature an on-chip JESD204B serial interface. By incorporating the 5-Gbps JESD204B interface, ADI’s new AD9671 octal receiver reduces ultrasound system I/O data routing by as much as 80 percent compared to other data interface standards. The resulting savings addresses the needs of manufacturers designing small, high-performance ultrasound systems by simplifying ultrasound equipment board design while better meeting industry demand for higher data rates, larger channel counts and greater image resolution.
The AD9671 receiver conditions eight channels of data from RF to a baseband frequency, reducing the processing load on the system FPGA (field-programmable gate array) by at least 50 percent compared to other receivers. The AD9671 integrates a low-noise amplifier, variable gain amplifier, anti-aliasing filter, and a 14-bit A/D converter with the industry’s highest sample rate (125 MSPS) and SNR (signal-to-noise ratio) performance (75 dB) for enhanced ultrasound image quality. The new octal receiver is the latest addition to Analog Devices’ award winning ultrasound receiver portfolio and is designed for mid- to high-end portable and cart-based ultrasound systems.
“By introducing the first octal ultrasound receiver with a multi-gigabit, serial data link, we are enabling ultrasound equipment designers to shrink the number of interconnects between their data converters and FPGAs,” said Pat O’Doherty, vice president, Healthcare segment, Analog Devices. “By incorporating the JESD204B serial interface, the AD9671 receiver not only simplifies PCB design and debug, it allows manufacturers to continue lowering design costs and reducing system size while maintaining excellent overall system performance.”
