摘要
针对多通道超声系统设计中接收电路中模拟前端和数字处理电路间的大数据量传输和大量数据连线的复杂性,提出了一个基于数字解调器和JESD204B接口的超声系统接收方案。该方案大幅降低了模拟前端的输出数据率,同时减少了模拟前端和数字电路部分的连线数目。有效地达到简化电路设计及降低数字处理要求,通过使用软件波束合成和更高阶多波束处理可以实现实时4D和高级影像模式。
A design based on digital demodulator and JESD204B interface for muhiple channel uhrasound receive system is introduced. The design reduces the data rate and simplifies board routing between the Analog Front End （AFE） and digital processing circuits. In addition, the ultrasound system can achieve more targets, such as utilization of cheaper and less computationally efficient Field Programmable Gate Array （FPGA）, software beamformer, and higher order muhiline processing for real-time 4D and advanced imaging modes.
