Octal ultrasound receiver with on chip serial interface is ‘industry’s first’
Analog Devices has unveiled what it claims is the industry's first octal ultrasound receiver to feature an on chip JESD204B serial interface.
Incorporating a 5Gb/s JESD204B interface, the AD9671 is designed to reduce ultrasound system I/O data routing by up to 80% compared to other data interface standards.
"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, vp of the healthcare segment at ADI. "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."
The AD9671 receiver conditions eight channels of data from rf to a baseband frequency, which ADI says reduces the processing load on the system fpga by at least 50%. It also integrates a low noise amplifier, variable gain amplifier, anti aliasing filter, and a 14bit A/D converter with what ADI claims is the industry's highest sample rate (125MSPS) and signal to noise ratio performance (75dB) for enhanced ultrasound image quality.
