Texas Instruments high-performance analog front-end for ultrasonic imaging provides flow velocity information

Recently, Texas instruments (TI) announced for high-end spectrum Doppler ultrasound device [watch video] launch 2 has a continuous wave (CW) Doppler mixer of the latest fully integrated analog front end (AFE).

The AFE5807 and AFE5808 0.75 nV/rtHz best noise performance, can fully meet the design staff on the excellent supersonic performance and image quality. In addition, the integrated CW mode can also be used in ultrasonic image measurement and display flow velocity. These latest devices than competitive solutions, small 25% to a higher channel count solution ensure compact system overall.

AFE5808 AFE5807 and other important characteristics and advantages

• Integrated CW Doppler summing mixer and amplifier near carrier phase noise is very low, at 2.5 MHz carrier under less than 1 KHz-155 dBc/Hz, simplifies the CW beam forming design; • AFE5807 is a low-power solution 1.1 nV/rtHz, 12-bit 40 MSPS and sampling instances per channel power 88 mW; • AFE5808 is a signal to noise ratio (SNR) is 77 dBFS, high performance solution that supports 0.75 nV/rtHz low noise optimization, 149 mW per channel power, 65 MSPS, 14-bit analog-to-digital converter (ADC); • 2 devices are integrated 8 channel component of the following: o a 24/18/12 dB gain settings of low noise amplifier (LNA), support 0.25/0.5/1 Vpp linear input range.

50, 100, 200 or 400 ohms for active Terminal supports a variety of input amplitude, can fully meet the needs of different types of transmitter needs; o voltage control Attenuator (VCA) and support the overall maximum gain up to 54 DB programmable gain amplifier (PGA) to achieve excellent dynamic range; o with 10, 15, 20 and 30 MHz selectable bandwidth of third order linear-phase low pass filter (LPF); o12-bit ADC with 14-bit, 65 MSPS with up; o of LVDS mode can optimize various programmable image mode power consumption and performance.

AFE5807 and further strengthen the TI AFE5808 AFE58xx fully integrated ultrasonic analog front end products camps, the series includes portable to midrange ultrasonic AFE5805 and AFE5804 and object-oriented handheld Super Portable Ultrasonic AFE5801 and AFE5851, etc.

All AFE58xx devices transmit are TI TX810 T/R switch, plus Ultrasonic application oriented TI's full range of embedded processing, analog and power management solution that helps manufacturers accelerate innovation ultrasonic systems listing process. Tools, the availability and packaging
