Octal ultrasound receiver with JESD204B serial interface reduces data I/O routing

Claimed as the first octal ultrasound receiver to feature an on-chip 5-Gbit/s JESD204B serial interface, the AD9671 is also claimed to reduce ultrasound system I/O data routing by as much as 80% compared to other data interface standards. The receiver conditions eight channels of data from RF to a baseband frequency, reducing the processing load on the system FPGA by at least 50% compared to other receivers.

The part integrates a low-noise amplifier, variable gain amplifier, anti-aliasing filter, and a 14-bit A/D converter with a sample rate of 125 Msamples/s (also claimed by the company, the highest) and SNR performance of 75 dB for enhanced ultrasound image quality. It offers a low power consumption of 130 mW/ch at 40 Msamples/s in time gain compensation mode and 55 mW/ch in CW mode.

It also offers a low noise of 0.78 nV/√Hz typical at 5 MHz (gain = 21.3 dB) and harmonic rejection to 13th order on CW-Doppler signals. It is available in a 144-ball 10 x 10 mm BGA. ($75.00 ea/1,000 — available now)
