Analog Devices Inc. AD9250-250EBZ

Overview

AD9250-250EBZ from Analog Devices is a customer evaluation board for the AD9250 dual 14-bit, 250 MSPS analog-to-digital converter. It enables FPGA-based high-speed data capture, supports JESD204B interface compliance testing, and provides configurable clocking and analog input paths for RF sampling validation in communications and instrumentation systems.

For engineers reviewing the AD9250-250EBZ datasheet, AD9250-250EBZ pinout, AD9250-250EBZ application, or AD9250-250EBZ equivalent, this board delivers validated signal integrity, SPI-controlled ADC configuration, real-time FFT analysis via VisualAnalog, and interoperability with the HSC-ADC-EVALDZ capture platform under defined power and clocking conditions.

Technical Context

The AD9250-250EBZ implements a dual-channel, interleaved sampling architecture with on-board clock conditioning circuitry supporting 10–14 dBm input clock levels at J505. It interfaces directly to the HSC-ADC-EVALDZ FPGA capture board via a standardized mezzanine connector, enabling JESD204B subclass 1 link initialization and deterministic latency verification.

Power delivery is segregated: the AD9250-250EBZ requires a dedicated 6 V, 2 A supply (e.g., CUI EPS060250UH-PHP-SZ), while the companion HSC-ADC-EVALDZ board uses a separate 12 V, 3.3 A supply (e.g., V-Infinity ETSA120330UDC-P5P-SZ). Default jumper settings (P204/P205/P206) configure single-ended analog inputs and internal reference mode.

FAQ

What is the AD9250-250EBZ used for?

The AD9250-250EBZ is an evaluation board for the AD9250 dual 14-bit, 250 MSPS analog-to-digital converter. It enables engineers to validate dynamic performance, configure JESD204B links, and perform FFT-based signal analysis using VisualAnalog and SPIController software. The AD9250-250EBZ does not function as a standalone product but serves exclusively as a test platform for the AD9250 IC under controlled lab conditions.

Does the AD9250-250EBZ include the AD9250 IC?

Yes, the AD9250-250EBZ evaluation board integrates the AD9250 dual 14-bit, 250 MSPS ADC as its core device. The board provides all necessary support circuitry including clock conditioning, analog input filtering paths, power regulation, and SPI interface routing - enabling full functional evaluation of the AD9250 IC without additional hardware.

What power supplies are required for the AD9250-250EBZ?

The AD9250-250EBZ requires a dedicated 6 V, 2 A switching power supply (e.g., CUI EPS060250UH-PHP-SZ). It must be used separately from the 12 V, 3.3 A supply powering the HSC-ADC-EVALDZ capture board. Using incorrect voltage or current ratings risks improper ADC biasing and invalidates performance measurements on the AD9250-250EBZ.

Which software tools are needed to operate the AD9250-250EBZ?

Operation of the AD9250-250EBZ requires VisualAnalog (Rev 1.9.20.21 or later) for FFT analysis and data visualization, and SPIController (Rev 1.0.91.3 or later) for register-level configuration. Configuration files AD9250_14Bit_250MSspiR03.cfg and macro AD9250_M2L2_SPI.mgp are mandatory for correct initialization of the AD9250 IC on the AD9250-250EBZ.

Is the AD9250-250EBZ compatible with other capture boards?

No - the AD9250-250EBZ is mechanically and electrically designed for use exclusively with the HSC-ADC-EVALDZ FPGA-based data capture board. Its mezzanine connector, pin mapping, power sequencing, and FPGA bitstream ("AD9250_12_04_11_1225.mcs") are specific to that platform. Interfacing with alternate capture hardware would require redesign of interface logic, timing constraints, and firmware support beyond the scope of the AD9250-250EBZ documentation.
