MAX2079 Low-Power, High-Performance, Fully Integrated Octal Ultrasound Receiver (Octal LNA, VGA, AAF, ADC, and CWD Beamformer) General Description Benefits and Features The MAX2079 fully integrated octal ultrasound receiver is optimized for high channel count, high-performance portable and cart-based ultrasound systems. The easyto-use integrated receiver allows the user to achieve high-end 2D and Doppler imaging capability using substantially less space and power. The highly compact low-noise amplifier (LNA), variable-gain amplifier (VGA), anti-alias filter (AAF), analog-to-digital converter (ADC), and digital highpass filter (HPF) achieve an ultra-low 2.8dB noise figure at RS = RIN = 200I with a very low 120mW per channel power dissipation at 50Msps. The full receive channel has been optimized for secondharmonic imaging with an exceptional 76dBFS SNR over a 2MHz bandwidth, and -70dBc second-harmonic distortion at fRF = 5MHz over the full receiver gain range. Near-carrier dynamic range has also been optimized for exceptional pulsed and color-flow Doppler performance under high-clutter conditions. The bipolar front-end and CMOS ADC achieve an exceptional near-carrier SNR of 137dBFS/Hz at 1kHz from a 5MHz tone for excellent lowvelocity Doppler sensitivity. The device also includes an octal CWD beamformer for a full Doppler solution. Separate mixers for each channel are available for optimal CWD sensitivity. The MAX2079 octal ultrasound front-end is available in a small, 10mm x 10mm, CTBGA package and is specified over the 0NC to +70NC temperature range.
