US-based Texas Instruments (TI) has launched new AFE5818 and AFE5816 products, which are claimed to be the industry's first 16-channel ultrasound analogue front ends (AFEs).

The AFEs incorporate a range of features to increase image quality and performance, while reducing power consumption and costs.

The introduction is part of the company's aim to meet increasing demand for healthcare diagnostic imaging devices, including customary prenatal care and advanced cardiac imaging equipment.

The company noted both products offer multiple versions with and without a demodulation block and JESD204B interface option to improve system efficiency.

The AFE products include a 5Gbps JESD204B serial interface, which helps to reduce ultrasound system data I/O routing by 80% compared against data interface standards and enables a data rate of up to 6.4Gbps.

"Both products offer multiple versions with and without a demodulation block and JESD204B interface option to improve system efficiency."

In addition, they feature a DTGC engine with 0.125dB resolution that decreases noise, power consumption and avoids the need for external components.

The new product lines include an on-chip digital demodulator that specifies 16 channels of data from RF to a baseband frequency.

In order to support the systems, the company also introduced ADS52J90, a 16-channel high-speed analogue to digital converter (ADC) that can be configured for up to 32 inputs.

The ADC provides on-chip digital demodulator for reducing processor or FPGA costs and a low-voltage differential signaling (LVDS) or JESD204B serial interface for faster data rates.

The company offers evaluation modules (EVMs) for the AFE5818, AFE5816 and ADS52J90 for quick and easy evaluation. Modules include AFE5818EVM, AFE58JD18EVM and AFE58JD16EVM, as well as ADS52J90EVM.

Texas Instruments, a global semiconductor design and manufacturing company, develops analogue integrated circuits and embedded processors.
