AFE58JD32LPZAV

Analog Front End (AFE) Overview

The AFE58JD32LPZAV is a 32-channel analog front-end (AFE) designed for portable ultrasound systems. It integrates low-noise amplifiers, programmable attenuators, programmable gain amplifiers, and third-order low-pass filters with cutoff frequencies from 10 MHz to 25 MHz. The device utilizes a multichip module architecture containing 16 ADCs that convert two VCA channels each, achieving maximum sample rates of 40 MSPS at 12-bit resolution or 50 MSPS at 10-bit resolution. Power consumption ranges from 18.5 mW/ch in low-power mode to 27.8 mW/ch in low-noise mode. It features a passive continuous wave mixer and digital I/Q demodulator, outputting data via LVDS or JESD204B interfaces within a 15 mm × 15 mm NFBGA-289 package.

Ensure compliance with RoHS standards and check moisture sensitivity level ratings before procurement. Confirm that the specific tray quantity and lead finish options match the project requirements.

Analog Front End (AFE) Selection Notes

Select this component when designing portable ultrasound systems requiring high integration and low power consumption. Choose between 12-bit/40 MSPS or 10-bit/50 MSPS modes based on the required signal-to-noise ratio and sampling speed. Ensure the host FPGA supports the LVDS or JESD204B interface speeds up to 1 Gbps. Verify thermal management capabilities for the NFBGA-289 package under maximum operating temperatures.

Analog Front End (AFE) Part Context

The AFE58JD32LPZAV belongs to the AFE58JD32LP family, which is pin-compatible with the AFE5832 series. It serves as a specialized solution for applications demanding small form factors and efficient power usage compared to higher-power alternatives like the AFE5818. The ZAV suffix indicates the specific NFBGA-289 packaging configuration.

Analog Front End (AFE) Replacement Considerations

The AFE58JD32LP is pin-compatible with the AFE5832 family. Designers should verify electrical parameter differences and software compatibility when substituting these devices.
