ANALOG ICs: AD9670/71 OCTAL ULTRASOUND AFE

摘要

The AD9670 was introduced as the industry's first octal (eight-channel) ultrasound receiver with on-chip digital I/Q demodulation and decimation filtering. Because of the embedded demodulation and decimation feature, it is the first ultrasound receiver able to condition eight channels of data from RF to a baseband frequency, reducing the processing load on the system FPGA by at least 50% compared with other receivers. By incorporating a 5-Gbit/sec JESD204B interface, the AD9671 reduces ultrasound system I/o data routing by as much as 80% compared with other data interface standards.
