製品の詳細

The MAX2088 is a highly integrated 16-channel ultrasound receiver optimized for high channel count, high performance portable and cart-based ultrasound systems.

Each channel of this highly compact receiver includes LNA, VGA, AAF, ADC, and several digital post processing circuits (including a digital HPF). It achieves an ultra-low 2.4dB noise figure at RS = RIN = 200Ω at a low 143mW per channel power dissipation when sampling at 50msps. Additionally, there is a lower power mode of operation that achieves 100mW per channel, but with reduced AC performance. The receive channel has been optimized for second harmonic imaging with -70dBFS second harmonic distortion performance at FIN = 5MHz over the full TGC range. Dynamic range has also been optimized for exceptional pulsed and color flow Doppler performance under high clutter conditions. The full receive channel exhibits an outstanding 81dBFS SNR at 5MHz with a 2MHz bandwidth. The bipolar front end and CMOS ADC have also been optimized for an exceptionally low, near-carrier modulation noise of -141dBc/Hz at 1KHz; offset from a 5MHz tone for excellent low-velocity Doppler sensitivity.

The device also includes a 16-channel CWD beamformer for a full Doppler solution. Separate mixers for each channel are made available for optimal CWD sensitivity, yielding an impressive 157dBc/Hz dynamic range per channel at 1KHz offset from a 2MHz carrier.

Furthermore, the MAX2088 also contains several digital post-processing options associated with digital mix-to-baseband operation. The device contains a 96dB SNR NCO, with a programmable frequency range from 800KHz to 17.6MHz with < 1KHz resolution. There is also a demodulation circuit, followed by a decimating FIR filter that can be programmed for different decimation ratios, where M can be programmed at any integer between 2 to 32. A 16xM tap low-pass FIR decimation filter is also provided. A post-decimation filter digital gain adjustment is also available.

When mixed-to-baseband is used, it is possible to reduce the number of LVDS output lanes required (from 20 pairs to 12 pairs) if decimation rates are ≥ 4.

The MAX2088 is offered in a 17mm x 16mm BGA package with 0.8mm ball pitch, and is specified over a 0°C to +85°C temperature range.

MAX2084EVKIT

説明

The MAX2084 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all components necessary to evaluate the performance of the MAX2084 low power, high performance 16-channel ultrasound receiver. The EV kit includes software compatible with the Windows XP®, Windows Vista®, and Windows 7® operating systems. The software provides a simple graphical user interface (GUI) for programming the features of the MAX2084 over a USB 3.0-compliant, super-speed interface. The MAX2084 digital LVDS outputs (VGA mode) are captured and stored using the companion Xilinx KC705 FPGA evaluation board for the Kintex-7 series FPGAs. In CWD mode, the CWD analog outputs are amplified, filtered and digitized using external circuitry, and the data is stored in the same manner. The FPGA board is compatible with Windows XP®, Windows Vista®, and Windows 7®.
