8-ch ultrasound receiver integrates digital demodulator and decimation filter

摘要

Offered as the first of its kind, the 8-channel AD9670 ultrasound receiver with on-chip digital I/Q demodulation and decimation filtering is 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 to other receivers. This part also integrates a low-noise amplifier, variable gain amplifier, anti-aliasing filter, and a 14-bit, A/D converter with the industry's highest sample rate of 125 Msamples/s and best SNR performance of 75 dB.
