Analog Devices Inc. AD9683-250EBZ

Overview

AD9683-250EBZ from Analog Devices is a full-featured evaluation board for the AD9683 14-bit, 250 MSPS analog-to-digital converter, supporting JESD204B serial output, dual-supply operation (1.8 V AVDD/DVDD/DRVDD), and flexible clocking via on-board oscillator or external RF/Nyquist sources up to 1.5 GHz. It enables AC performance characterization in high-speed data acquisition, radar, and communications test benches.

For engineers reviewing the AD9683-250EBZ datasheet, AD9683-250EBZ pinout, AD9683-250EBZ application, or AD9683-250EBZ equivalent, this board provides validated signal chain integration-including balun-coupled analog input, ADL5202 variable-gain amplifier option, AD9525 clock generator support, SPI-controlled configuration, and HSC-ADC-EVALDZ FPGA capture compatibility-critical for JESD204B-based system prototyping.

Technical Context

The AD9683-250EBZ implements a complete reference design for the AD9683 ADC, featuring dual-domain power conditioning (1.8 V analog/digital/DRVDD with isolated LDOs), transformer-coupled Nyquist clock input (CLK+ SMA), and RF clock input (RF_CLK SMA) supporting 625 MHz–1.5 GHz with internal /2 or /4 pre-divider plus 8:1 clock divider. It supports both passive (balun) and active (ADL5202) analog input paths with configurable filtering and gain control.

Hardware configuration is managed via jumpers (P202, P204–P210) enabling domain isolation, ADL5202 biasing (5.0 V/3.3 V), JESD204B driver power coupling (DVDD↔DRVDD), and FPGA reference clock routing (P504). SPI interface connects to PC via USB through HSC-ADC-EVALDZ, with VisualAnalog® and SPIController software providing real-time FFT analysis and register-level device control.

FAQ

What is the primary function of the AD9683-250EBZ?

The AD9683-250EBZ is an evaluation board-not a semiconductor component-that provides all necessary circuitry, firmware, and software interfaces to characterize and prototype with the AD9683 14-bit, 250 MSPS analog-to-digital converter. It enables functional validation, AC performance testing (SNR, SFDR), and JESD204B link setup without custom PCB design. The AD9683-250EBZ includes on-board LDOs, clock options, analog input flexibility, and full VisualAnalog®/SPIController integration.

Does the AD9683-250EBZ support both Nyquist and RF clock modes?

Yes, the AD9683-250EBZ supports both clocking architectures: Nyquist mode via the CLK+ SMA connector (transformer-coupled, 50 Ω, optimized for ≤500 MHz clocks), and RF clock mode via the RF_CLK SMA connector (single-ended, 625 MHz–1.5 GHz), enabled via SPI register configuration. The AD9683-250EBZ hardware includes jumper-selectable biasing (P202/P209) and clock routing (P504) to ensure proper domain synchronization for either mode.

Can the AD9683-250EBZ be used with the AD6677?

No-the AD9683-250EBZ is specifically configured for the AD9683 14-bit, 250 MSPS ADC and is not compatible with the AD6677, which has different pinout, power sequencing, JESD204B lane count, and internal clock architecture. While both devices share the same evaluation board form factor (AD9683-250EBZ vs. AD6677EBZ), Analog Devices documents them as separate, non-interchangeable boards with distinct schematics, BOMs, and jumper configurations.

What power supplies are required to operate the AD9683-250EBZ?

The AD9683-250EBZ requires one 6 V, 2.5 A switching power supply (e.g., CUI EPS060250UH-PHP-SZ) connected to P201 for on-board LDO operation. For advanced use cases-such as domain-isolated biasing or AD9525/ADL5202 operation-external 1.8 V (0.5 A), 3.3 V (0.5 A), and 5.0 V (0.5 A) supplies may be connected via P1, P208, and P502. Default operation uses only the 6 V supply.

Which software tools are supported for configuring and analyzing data from the AD9683-250EBZ?

The AD9683-250EBZ is fully supported by Analog Devices' VisualAnalog® (for FFT-based performance analysis, template-driven capture, and real-time signal visualization) and SPIController (for low-level register access, clock divider selection, JESD204B lane configuration, and power mode control). Both tools interface via USB to the HSC-ADC-EVALDZ FPGA capture board, and configuration files are part-number-specific-ensuring correct initialization of the AD9683-250EBZ's target device.
