Analog Devices Inc. AD9680-500EBZ

Overview

AD9680-500EBZ from Analog Devices is a full-featured evaluation board for the AD9680-500 dual 14-bit analog-to-digital converter, supporting JESD204B serial interface, 500 MSPS per channel sampling, and wideband balun-driven differential input. It enables high-fidelity signal acquisition in radar, communications, and instrumentation systems requiring precise spectral analysis and low jitter timing.

For engineers reviewing the AD9680-500EBZ datasheet, AD9680-500EBZ pinout, AD9680-500EBZ application, or AD9680-500EBZ equivalent, this page delivers verified hardware configuration details, FPGA firmware compatibility (ADS7-V1EBZ), VisualAnalog® and SPIController software integration, and validated test setup requirements including 12 V/6.5 A supply, 1 GHz sample clock at +14 dBm, and REFCLK at +10 dBm.

Technical Context

The AD9680-500EBZ implements a complete reference platform for evaluating the AD9680-500 ADC in full-bandwidth mode with L=4, M=2, F=1 JESD204B lane configuration. It interfaces directly with the ADS7-V1EBZ FPGA capture kit via FMC connector and uses preprogrammed bin files (e.g., ad9680_ads7v1_20140821_1351.bin) to support real-time data streaming at up to 1 MSPS aggregate throughput.

Board-level features include on-board SPI control for register access, dual-channel analog input paths (P200/P202) with 50 Ω coaxial termination, dedicated clock inputs (J801 for sample clock, J804 for FPGA REFCLK), and power delivery via FMC-supplied 12 V–1 A and 3.3 V–3 A rails - eliminating need for external DC supplies beyond the ADS7-V1EBZ host system.

FAQ

What is the AD9680-500EBZ used for?

The AD9680-500EBZ is an evaluation board for the AD9680-500 dual 14-bit ADC, enabling engineers to validate dynamic performance (SNR, SFDR), JESD204B link stability, and system-level timing margins. It supports rapid development of radar, electronic warfare, and wireless infrastructure receivers where 500 MSPS sampling and deterministic data transport are critical. The AD9680-500EBZ requires ADS7-V1EBZ for data capture and VisualAnalog® for FFT analysis.

Does the AD9680-500EBZ require external power supplies?

No - the AD9680-500EBZ draws all required power (12 V–1 A and 3.3 V–3 A) from the FMC host interface, such as the ADS7-V1EBZ. No additional DC power supplies are needed, simplifying lab setup and reducing noise coupling risks. The AD9680-500EBZ relies entirely on the host board's regulated rails and does not include onboard DC-DC conversion circuitry.

Which FPGA firmware is compatible with the AD9680-500EBZ?

The AD9680-500EBZ requires the ADS7-V1EBZ-compatible FPGA bin file ad9680_ads7v1_20140821_1351.bin, available from Analog Devices' FTP site. This firmware configures the ADS7-V1EBZ's transceivers and data path for JESD204B lane rate matching and proper framing of the AD9680-500's 4-lane output. Using mismatched firmware will prevent link initialization or cause data corruption in the AD9680-500EBZ evaluation flow.

Can the AD9680-500EBZ be used without the ADS7-V1EBZ?

No - the AD9680-500EBZ lacks onboard data capture logic and relies on the ADS7-V1EBZ FPGA-based platform for JESD204B decoding, memory buffering, and USB 2.0 streaming to PC. Without ADS7-V1EBZ (or functionally identical host), the AD9680-500EBZ cannot acquire, process, or export sampled data. The AD9680-500EBZ functions solely as a signal conditioning and interface adapter for the target ADC.

What software tools are required to operate the AD9680-500EBZ?

Operation requires Analog Devices' VisualAnalog® (for FFT visualization and data capture control) and SPIController (for register-level configuration of the AD9680-500). Both tools are freely available from ftp.analog.com. VisualAnalog® loads prebuilt canvases for AD9680, while SPIController manages PLL lock detection (register 0x56F), JESD204B quick config (0x570), and lane rate (0x56E). The AD9680-500EBZ does not support standalone GUI operation outside this toolchain.
