Analog Devices Inc. AD9467-250EBZ

Overview

AD9467-250EBZ from Analog Devices is a fully featured evaluation board designed exclusively for the AD9467BCPZ-250 16-bit, 250 MSPS analog-to-digital converter. It provides complete signal chain support including transformer-coupled clock input, single-ended 50 Ω analog front-end with 350 MHz bandwidth, internal/external reference options (1.25 V ADR130 or default 2.5 V p-p), and SPI-controlled configuration via AD9517 clock generator and on-board FPGA interface.

For engineers reviewing the AD9467-250EBZ datasheet, AD9467-250EBZ pinout, AD9467-250EBZ application, or AD9467-250EBZ equivalent, this board enables rapid characterization of SFDR, SNR, and ENOB under real-world conditions using VisualAnalog and SPI Controller software - critical for high-speed data acquisition, radar IF sampling, and communications test equipment development.

Technical Context

The AD9467-250EBZ implements a dual-path power architecture: dedicated low-noise LDOs (ADP1706/ADP1708) deliver regulated 1.8 V (AVDD1/DRVDD), 3.3 V (AVDD2), and 3.3 V analog (3P3V_AVDD) rails, with independent fuse-protected inputs and ferrite-bead filtering. Clocking supports three modes: default 250 MHz Vectron VCC6-QCD oscillator (Y200), transformer-coupled single-ended input (T201), or active LVPECL/LVDS drive via AD9517-4BCPZ (U300).

Analog input uses SMA-J-P-X-ST-EM1 connectors feeding a passive network with ADL5562 preamplifier stage and MABA-007159 baluns; digital outputs route through 60-pin high-speed backplane connector P502 to HSC-ADC-EVALCZ capture board, supporting parallel CMOS/LVDS DCO and data bus (D0–D15) with optional on-board terminations (R500–R509).

FAQ

What is the primary function of the AD9467-250EBZ evaluation board?

The AD9467-250EBZ evaluation board is a dedicated hardware platform for characterizing the AD9467BCPZ-250 16-bit, 250 MSPS analog-to-digital converter. It provides all necessary support circuitry - including clock generation, analog input conditioning, reference selection, power regulation, and digital output interfacing - enabling engineers to measure key performance metrics like SFDR, SNR, and ENOB without custom PCB design. The AD9467-250EBZ integrates seamlessly with VisualAnalog and SPI Controller software for rapid system-level validation.

Which ADC does the AD9467-250EBZ support, and what are its core specifications?

The AD9467-250EBZ is designed exclusively for the AD9467BCPZ-250: a 16-bit, 250 MSPS pipeline ADC in a 72-lead LFCSP package. Its confirmed specifications include 78.2 dBFS SNR, 92.2 dBc SFDR, and 7.9 ENOB at 125 MHz input frequency with 250 MSPS sampling. The AD9467-250EBZ board maintains these performance levels through low-jitter clock routing, optimized analog front-end matching, and segregated analog/digital power domains - all verified per UG-200 documentation.

Does the AD9467-250EBZ include on-board clock generation, and if so, what type?

Yes, the AD9467-250EBZ includes an on-board 250 MHz low-phase-noise crystal oscillator (Vectron VCC6-QCD-250M000, Y200) as the default clock source. Jumper P200 controls oscillator enable/disable. Alternative clock paths include transformer-coupled single-ended input (T201) and active LVPECL/LVDS drive via the AD9517-4BCPZ clock generator (U300), configurable via SPI. All clock paths are validated to maintain <1 ps RMS jitter - essential for preserving the AD9467-250EBZ's dynamic performance.

How is analog input configured on the AD9467-250EBZ, and what bandwidth does it support?

The AD9467-250EBZ uses a single-ended analog input path with 50 Ω impedance match and 350 MHz bandwidth, implemented via SMA-J-P-X-ST-EM1 connector, ADL5562 preamplifier, and MABA-007159 balun. This configuration is optimized for fundamental tones up to Nyquist (125 MHz) while suppressing harmonics and broadband noise. The board supports external band-pass filtering (e.g., TTE or K&L Microwave filters) directly at the input connector to meet AD9467's specified noise floor requirements - a key design feature documented in UG-200 Section 5.

What software tools are required to operate the AD9467-250EBZ, and where are they obtained?

Operation of the AD9467-250EBZ requires VisualAnalog (for FFT analysis and data visualization) and SPI Controller (for register-level ADC configuration), both provided free by Analog Devices at analog.com/fifo. These tools interface via USB 2.0 to the HSC-ADC-EVALCZ FPGA capture board, which connects to the AD9467-250EBZ through P502. Supporting documentation includes AN-905 (VisualAnalog), AN-878 (SPI control), and AN-877 (SPI interface guidelines) - all referenced in the AD9467-250EBZ User Guide UG-200.
