Analog Devices Inc. AD9625-2.5EBZ

Overview

AD9625-2.5EBZ from Analog Devices is a high-speed analog-to-digital converter evaluation board designed to validate the AD9625 12-bit, 2.5 GSPS ADC under real-world signal acquisition conditions using the HSC-ADC-EVALEZ FPGA-based capture platform. It supports JESD204B subclass 1 interface, operates with dual 12 V supplies, and enables FFT-based performance analysis up to 2 GHz input bandwidth.

For engineers reviewing the AD9625-2.5EBZ datasheet, AD9625-2.5EBZ pinout, AD9625-2.5EBZ application, or AD9625-2.5EBZ equivalent, this board provides validated hardware setup, SPI-controlled register configuration via SPIController software, VisualAnalog-based spectral analysis, and JESD204B lane alignment verification for high-speed data converter system integration.

Technical Context

The AD9625-2.5EBZ implements a full-signal-chain test environment for the AD9625 ADC, including balun-coupled single-ended-to-differential analog input, low-jitter clock distribution via SMA, and FMC-based interconnection to the HSC-ADC-EVALEZ capture board. It requires two independent 12 V DC power supplies and supports configurable JESD204B lane counts (2/4/8) aligned to sample rates from 330 MSPS to 2000 MSPS.

Signal integrity is maintained through controlled-impedance routing, SMA-connected clock and analog inputs, and on-board SPI interface for register access. The board does not include an onboard clock generator or FPGA - both are provided by the companion HSC-ADC-EVALEZ board and external sources per the Quick Start Guide.

FAQ

What is the primary function of the AD9625-2.5EBZ?

The AD9625-2.5EBZ is an evaluation board dedicated to characterizing the AD9625 12-bit, 2.5 GSPS analog-to-digital converter. It provides physical interface, power delivery, signal conditioning, and JESD204B connectivity to enable functional validation, dynamic performance testing (e.g., SNR, SFDR), and FPGA-based system integration - all without requiring custom PCB design. The AD9625-2.5EBZ must be used with the HSC-ADC-EVALEZ capture board and VisualAnalog/SPIController software tools.

Does the AD9625-2.5EBZ include an onboard clock generator?

No, the AD9625-2.5EBZ does not include an onboard clock generator. It requires an external low-jitter clock source connected via SMA, with specified input levels between 500 mVpp and 2000 mVpp at the connector. Clock distribution and FPGA configuration are handled by the companion HSC-ADC-EVALEZ board, not the AD9625-2.5EBZ itself.

Which software tools are required to operate the AD9625-2.5EBZ?

Two mandatory software tools are required: VisualAnalog for FFT-based spectral analysis and real-time data visualization, and SPIController for register-level configuration of the AD9625 via its SPI interface. Both tools load AD9625-specific configuration files and are distributed by Analog Devices. The AD9625-2.5EBZ cannot be operated without these tools and the HSC-ADC-EVALEZ capture board.

Can the AD9625-2.5EBZ be used independently without the HSC-ADC-EVALEZ board?

No, the AD9625-2.5EBZ cannot function independently. It relies entirely on the HSC-ADC-EVALEZ FPGA-based data capture board for JESD204B link initialization, FPGA programming, USB host communication, and data streaming to the PC. The AD9625-2.5EBZ has no USB interface, onboard memory, or processing capability - it serves solely as the ADC interface and signal conditioning stage.

What analog input configuration does the AD9625-2.5EBZ support?

The AD9625-2.5EBZ supports single-ended analog input via SMA, converted to differential using an onboard balun to match the AD9625's differential input requirement. This eliminates the need for external active differential drivers during lab evaluation. Input amplitude is adjusted externally, and the board provides no gain control or programmable attenuation - signal level optimization occurs in the source generator or post-processing.
