Small ultrasound AFE designed to deliver high performance and low power

The Texas Instruments AFE58JD32 device is a highly-integrated, analog front-end solution specifically designed for ultrasound systems where high performance, low power, and small size are required. The device is an integrated AFE optimized for medical ultrasound application. The device is realized through a MCM with three dies: two VCA dies and one ADC die. Each VCA die has 16 channels and the ADC die converts all of the 32 channels. The device includes an optional digital demodulator and JESD204B data packing blocks. The digital in-phase and quadrature (I/Q) demodulator with programmable decimation filters accelerates computationally-intensive algorithms at low power. The device also supports an optional JESD204B interface that runs up to 5Gbps and further reduces the circuit-board routing challenges in high-channel count systems. The device also allows various power and noise combinations to be selected for optimizing system performance. Therefore, this device is a suitable ultrasound AFE solution for systems with strict battery-life requirements.
