Analog Devices Inc. AD9269-40EBZ

Overview

AD9269-40EBZ from Analog Devices is a full-featured evaluation board designed to characterize the AD9269 16-bit, 40 MSPS analog-to-digital converter (ADC) in multiple configurations. It supports transformer-coupled analog input up to ~150 MHz, on-board 40/65/80 MHz Valpey Fisher oscillator clocking, and SPI-based setup via VisualAnalog® and SPI Controller software.

For engineers reviewing the AD9269-40EBZ datasheet, AD9269-40EBZ pinout, AD9269-40EBZ application, or AD9269-40EBZ equivalent, this board enables rapid ac performance validation-including SNR, SFDR, and ENOB-under real-world signal chain conditions with low-phase-noise clocking, flexible power options (LDO or ADP2114 switching regulators), and dual-channel CMOS output capture via HSC-ADC-EVALCZ.

Technical Context

The AD9269-40EBZ implements a dedicated hardware platform for the AD9269 ADC, featuring a default double-balun analog input path with 50 Ω termination, internal 1 V reference (2 V p-p full-scale), and RBIAS set to 10 kΩ for optimal core bias current. It supports both single-ended sine-wave clock inputs (via T601 transformer) and differential LVPECL clocking through an optional AD9517 PLL generator.

Power delivery includes configurable LDO regulation (default) or ADP2114 dc-dc conversion for AVDD/DRVDD rails, with separate 1.8 V analog/digital supplies and optional 3.3 V analog support. Output data routing uses U801/U802 buffers to drive CMOS signals from Channel A and B to the HSC-ADC-EVALCZ FPGA capture interface.

FAQ

What is the primary function of the AD9269-40EBZ?

The AD9269-40EBZ is an evaluation board-not a semiconductor component-designed exclusively to evaluate the AD9269 16-bit, 40 MSPS analog-to-digital converter. It provides all necessary support circuitry including clock generation, analog input conditioning, power regulation, SPI interface, and CMOS output buffering. The AD9269-40EBZ enables engineers to validate dynamic performance metrics such as SNR, SFDR, and harmonic distortion under controlled lab conditions before system integration.

Which ADC does the AD9269-40EBZ support?

The AD9269-40EBZ is specifically configured for the AD9269 16-bit, 40 MSPS analog-to-digital converter. While the board's hardware accommodates other members of the AD9269 family-including AD9251, AD9231, AD9204, and AD6659-the default jumper settings, input network (Figure 5), reference voltage (1.0 V), and oscillator selection are optimized for the AD9269. Using it with other parts requires verifying compatibility per their respective datasheets.

Does the AD9269-40EBZ include an on-board clock source?

Yes, the AD9269-40EBZ includes a factory-installed Valpey Fisher VFAC3-BHL-40MHz oscillator (Y601) as its default clock source. This low-phase-noise crystal oscillator feeds the ADC via a transformer-coupled path (T601) and is enabled by installing jumper J605. Users may disable it and apply an external clock signal through SMA connector J602 (labeled ENCODE+) for alternative timing validation.

What software tools are required to operate the AD9269-40EBZ?

Two primary software tools are required: VisualAnalog® for FFT-based performance analysis and real-time data visualization, and the SPI Controller software for register-level configuration of the AD9269 via its serial interface. Both tools are freely available from Analog Devices' website and integrate directly with the AD9269-40EBZ's onboard SPI bus and HSC-ADC-EVALCZ FPGA capture platform.

Can the AD9269-40EBZ be powered using bench supplies instead of the included wall adapter?

Yes, the AD9269-40EBZ supports external bench power supplies. To do so, ferrite beads E101, E102, E114, E103, E105, and E107 must be removed to isolate the on-board LDOs, then 1.8 V (1 A) supplies for DUT_AVDD/DRVDD and DVDD, plus a 3.3 V analog supply (1 A) for clock circuitry, are connected via headers P102 and P103. This allows independent biasing of analog and digital domains for noise-sensitive measurements.
