Analog Devices Inc. AD9269-80EBZ

Overview

AD9269-80EBZ from Analog Devices is a full-featured evaluation board designed to characterize the AD9269 16-bit, 80 MSPS analog-to-digital converter under real-world signal chain conditions. It supports transformer-coupled differential analog input up to ~150 MHz, on-board 80 MHz Valpey Fisher VFAC3-BHL-80MHz low-phase-noise oscillator, and SPI-based configuration via VisualAnalog® and SPI Controller software.

For engineers reviewing the AD9269-80EBZ datasheet, AD9269-80EBZ pinout, AD9269-80EBZ application, or AD9269-80EBZ equivalent, this board enables rapid validation of AC performance (SNR, SFDR), clocking architecture compatibility (LVPECL, transformer-coupled), power supply configurations (LDO vs. ADP2114 switching regulator), and interface timing margins with FPGA-based data capture systems.

Technical Context

The AD9269-80EBZ implements a dual-channel, 16-bit, 80 MSPS ADC evaluation platform with configurable analog front-end drive options including balun-coupled inputs and optional AD8375 DVGA on Channel A or ADL5562 amplifier on Channel B. It supports internal 1 V reference (2 V p-p full-scale) and fixed RBIAS biasing at 10 kΩ for optimal core linearity.

Its clock subsystem offers three modes: default transformer-coupled 80 MHz oscillator (VFAC3-BHL-80MHz), external SMA-connected single-ended sine wave (50 Ω terminated), or AD9517-based LVPECL differential clock generation. Power delivery includes selectable LDO regulation or ADP2114 dual buck converter for AVDD/DRVDD rails.

FAQ

What is the primary function of the AD9269-80EBZ evaluation board?

The AD9269-80EBZ evaluation board is a dedicated hardware platform for evaluating the AD9269 16-bit, 80 MSPS analog-to-digital converter. It provides all necessary support circuitry-including clock generation, analog input conditioning, power regulation, and SPI-based configuration-to validate AC performance metrics like SNR and SFDR under controlled lab conditions. The AD9269-80EBZ does not operate as a standalone product but serves exclusively as a characterization tool for the AD9269 IC.

Does the AD9269-80EBZ include an on-board clock source?

Yes, the AD9269-80EBZ includes an on-board 80 MHz Valpey Fisher VFAC3-BHL-80MHz low-phase-noise oscillator (Y601) as the default clock source for the AD9269. This oscillator connects via transformer T601 to provide a clean differential clock signal. The board also supports external clock injection through SMA connector J602 and optional AD9517-based LVPECL clock synthesis, making the AD9269-80EBZ flexible across multiple clocking architectures.

Can the AD9269-80EBZ be used to evaluate other ADCs besides the AD9269?

Yes - the AD9269-80EBZ is part of a shared evaluation platform covering the AD9269 family, which includes the AD9251, AD9231, AD9204, and AD6659. While optimized for the AD9269, its hardware layout, jumper settings, and default configurations (e.g., 1 V internal reference, 150 MHz input bandwidth, 10 kΩ RBIAS) are validated across this group. Each device requires its own SPI configuration file and data sheet–specific setup, but the AD9269-80EBZ board serves as a common test vehicle.

What software tools are required to operate the AD9269-80EBZ?

Two primary software tools are required: VisualAnalog® for FFT-based AC performance analysis (SNR, SFDR, harmonic distortion) and the SPI Controller software for register-level configuration of the AD9269. Both tools run on Windows PCs and interface via USB to the HSC-ADC-EVALCZ FPGA data capture board, which connects directly to the AD9269-80EBZ. The AD9269-80EBZ user guide (UG-003) references AN-905, AN-878, and AN-877 for detailed usage instructions.

How is power delivered to the AD9269-80EBZ and what options exist?

The AD9269-80EBZ ships with a 6 V, 2.5 A CUI EPS060250UH-PHP-SZ switching power supply connected via barrel jack P101. On-board LDOs generate 1.8 V for AVDD/DRVDD and DVDD rails by default. Alternatively, users can reconfigure the board to use the ADP2114 dual buck converter for AVDD/DRVDD - requiring specific resistor, capacitor, and inductor placements per UG-003 guidelines. This switching option improves power efficiency but requires hardware modification before use.
