Analog Devices Inc. AD9279-80KITZ

Overview

AD9279-80KITZ from Analog Devices is an evaluation kit for the AD9279 octal-channel ultrasound analog front-end IC, integrating LNA, VGA, AAF, 12-bit ADC, and CW I/Q demodulator per channel. It supports TGC and CW Doppler modes up to 80 MSPS, delivers 70 dB SNR, and targets medical ultrasound beamforming systems requiring high channel density and low power.

For engineers reviewing the AD9279-80KITZ datasheet, AD9279-80KITZ pinout, AD9279-80KITZ application, or AD9279-80KITZ equivalent, this kit enables rapid validation of signal chain performance-including input-referred noise (0.75 nV/√Hz), programmable phase rotation (22.5° steps), and LVDS serial output compliance-within medical imaging and automotive radar development environments.

Technical Context

The AD9279-80KITZ provides full hardware and software support for evaluating the AD9279's dual-mode operation: time-gain compensation (TGC) with 45 dB VGA range and CW Doppler mode with independent per-channel I/Q demodulation. It implements the complete analog signal path-including active input termination, programmable second-order LPF (8–18 MHz), and 12-bit LVDS ADC-with synchronized clocking and SPI-controlled configuration.

Kit-level features include on-board 4LO generation, configurable gain control interface (0–1.6 V single-ended), reference voltage regulation (1.0 V ±50 mV), and thermal management aligned with the AD9279's 22.0°C/W θJA. All eight channels are independently accessible via edge-mounted SMA connectors and routed to FPGA-compatible LVDS headers.

FAQ

What is the primary function of the AD9279-80KITZ?

The AD9279-80KITZ is an evaluation kit designed exclusively for the AD9279 octal-channel ultrasound analog front-end IC. It provides complete hardware infrastructure-including power regulation, clock distribution, signal routing, and SPI interface-to validate the AD9279's TGC and CW Doppler modes in real-world medical imaging and radar applications. The kit does not contain a standalone IC but enables full characterization of the AD9279 device.

Does the AD9279-80KITZ support both TGC and CW Doppler modes of the AD9279?

Yes, the AD9279-80KITZ fully supports both operational modes of the AD9279. It includes dedicated circuitry for generating and distributing the 4LO signal required for CW demodulation, configurable gain control voltage inputs (GAIN+/GAIN−), and independent access to all eight channel inputs (LI-A through LI-H) and outputs (CWI+/CWI−, CWQ+/CWQ−, DOUTA+ through DOUTH+). Mode selection is controlled via SPI register writes to the AD9279 mounted on the board.

What interfaces and connectivity options does the AD9279-80KITZ provide?

The AD9279-80KITZ offers SMA connectors for all eight analog inputs (LI-A to LI-H), SMA outputs for CW I/Q signals (CWI+/CWI−, CWQ+/CWQ−), and LVDS-compatible headers for digital outputs (DOUTA+ to DOUTH+, FCO+, DCO+). It also provides standard 0.1" pitch headers for SPI (SCLK, SDIO, CSB), control signals (PDWN, STBY, RESET), and power rails (AVDD1, AVDD2, DRVDD), enabling direct connection to host FPGAs or microcontrollers.

Can the AD9279-80KITZ be used with third-party FPGA development platforms?

Yes, the AD9279-80KITZ is designed for interoperability with industry-standard FPGA platforms. Its LVDS digital outputs comply with ANSI-644 and IEEE 1596.3 specifications, and its 1.8 V logic levels match common FPGA I/O banks. Pin-aligned headers deliver serialized ADC data, frame clock (FCO+), and digital clock output (DCO+) with documented timing margins (e.g., tDATA skew < ±350 ps), allowing seamless integration into Xilinx or Intel FPGA-based ultrasound processors.

Is software and firmware provided with the AD9279-80KITZ?

Yes, Analog Devices supplies comprehensive evaluation software for the AD9279-80KITZ, including GUI-based configuration tools, register map editors, real-time data capture utilities, and MATLAB-compatible scripts. Firmware for on-board microcontrollers handles SPI initialization, power sequencing, and status monitoring. All software is available via Analog Devices' official website under the AD9279 product page and requires no license fee for evaluation use.
