Using Calibration to Optimize Performance in Crucial Measurements
Analog Devices Inc. introduced the AD9675 8-channel ultrasound analog front end (AFE) with on-chip RF decimator and JESD204B serial interface, designed for mid- to high-end portable and cart-based medical and industrial ultrasound systems. The device integrates eight channels of low-noise amplifier, variable-gain amplifier, anti-aliasing filter, and 14-bit A/D converter with the industry’s highest sample rate (125 MSPS) and best SNR (signal-to-noise ratio) performance (75 dB) for enhanced ultrasound image quality. The on-chip RF decimator enables the ADC to be oversampled providing increased SNR for improved image quality while maintaining lower data I/O rates. The 5-Gbps JESD204B serial interface reduces ultrasound system I/O data routing compared to other data interface standards by as much as 80%. These features simplify ultrasound board design, while better addressing industry demand for higher data rates, larger channel counts and greater image resolution. A second model, the AD9674, offers the same basic functionality but is available with standard LVDS interface. The AD9675 and AD9674 are the latest additions to Analog Devices’ award-winning octal ultrasound receiver portfolio.
The AD9675 and AD9674 are available in a space-saving 144-ball, 10 mm x 10 mm BGA package and are pin compatible with the AD9670/AD9671, providing easy migration for those designs that require a reduced cost and limited digital functionality.
