Analog Devices Inc. AD6673-250EBZ

Overview

AD6673-250EBZ from Analog Devices is an evaluation board designed to characterize the AD6673-250, a 14-bit, 250 MSPS dual-channel analog-to-digital converter (ADC) with JESD204B serial interface, used in high-speed data acquisition, communications infrastructure, and instrumentation systems.

For engineers reviewing the AD6673-250EBZ datasheet, AD6673-250EBZ pinout, AD6673-250EBZ application, or AD6673-250EBZ equivalent, this board enables full performance validation of the AD6673-250 ADC under real-world signal chain conditions-including clock jitter sensitivity, SFDR, SNR, and JESD204B link integrity-with FPGA-based capture via the HSC-ADC-EVALDZ platform.

Technical Context

The AD6673-250EBZ interfaces directly with the HSC-ADC-EVALDZ FPGA capture board via high-speed mezzanine connectors, supporting JESD204B subclass 1 lane configuration at up to 5 Gbps per lane. It accepts differential analog inputs at J301 (Channel A) and J303 (Channel B), and requires a clean 10–14 dBm RF clock input at J505.

Power delivery is split across two dedicated supplies: 6 V/2 A for the AD6673-250 ADC section and 12 V/3.3 A for the HSC-ADC-EVALDZ board. Configuration and register control are performed over SPI using preloaded macro files (e.g., AD6673_M2L2_SPI.mgp) and VisualAnalog software for FFT-based performance analysis.

FAQ

What is the AD6673-250EBZ used for?

The AD6673-250EBZ is an evaluation board for the AD6673-250 ADC, enabling engineers to validate dynamic performance metrics-including SNR, SFDR, and ENOB-at 250 MSPS under controlled analog input and clock conditions. It is not a standalone product but a reference platform requiring the HSC-ADC-EVALDZ capture board and VisualAnalog software to operate.

Does the AD6673-250EBZ include the AD6673-250 IC?

Yes, the AD6673-250EBZ board integrates the AD6673-250 IC as its core device. The board provides all necessary power regulation, clock conditioning, analog input filtering, and JESD204B interface routing to support full characterization of the AD6673-250's dual-channel 14-bit conversion capability.

What external hardware is required to use the AD6673-250EBZ?

To operate the AD6673-250EBZ, you must provide: a clean RF clock source (10–14 dBm into J505), differential analog signal generators (8–12 dBm into J301/J303), two switching power supplies (6 V/2 A and 12 V/3.3 A), a PC with USB 2.0, the HSC-ADC-EVALDZ FPGA capture board, and compatible software (VisualAnalog and SPIController).

Can the AD6673-250EBZ be used without the HSC-ADC-EVALDZ board?

No-the AD6673-250EBZ lacks on-board data capture or storage and relies entirely on the HSC-ADC-EVALDZ board for JESD204B link handling, FPGA-based buffering, and USB data transfer to a host PC. The two boards connect mechanically and electrically via standardized mezzanine headers and cannot function independently for data acquisition.

Is the AD6673-250EBZ RoHS compliant and ESD-safe?

Yes, the AD6673-250EBZ complies with RoHS Directive 2011/65/EU and incorporates ESD protection circuitry. However, it is labeled ESD-sensitive: users must observe proper grounding, wrist straps, and antistatic handling procedures during setup, probing, or modification to prevent latent damage to the AD6673-250 IC or supporting components.
