Analog Devices Inc. AD9286-500EBZ

Overview

AD9286-500EBZ from Analog Devices is a full-featured evaluation board for the AD9286 8-bit, 500 MSPS dual-channel analog-to-digital converter (ADC), supporting LVDS or CMOS output modes, external or on-board oscillator clocking, and transformer- or amplifier-based analog input drive. It enables high-fidelity ac performance characterization up to ~200 MHz analog input frequency with <1 ps rms jitter clock requirement.

For engineers reviewing the AD9286-500EBZ datasheet, AD9286-500EBZ pinout, AD9286-500EBZ application, or AD9286-500EBZ equivalent, this board provides FPGA-based data capture via HSC-ADC-EVALCZ, SPI-controlled configuration using VisualAnalog and SPIController software, and validated layout practices for high-speed ADC system design.

Technical Context

The AD9286-500EBZ implements a complete signal chain for the AD9286 ADC, including low-noise power regulation (1.8 V AVDD/DRVDD, 3.3 V clock/amp supplies), transformer-coupled or active (ADA4937-1) differential analog input paths, and configurable LVDS/CMOS output termination networks. It supports interleaved dual-channel sampling at 500 MSPS with 1.2 V p-p full-scale input range set by an internal 1.0 V reference.

Board-level features include jumper-selectable SPI/non-SPI operation, separate clock enable for Channel B (via J204), RBIAS bias current tuning (R206 = 10 kΩ), and dual 6 V/2.5 A switching power supply inputs - one for the ADC board and one for the HSC-ADC-EVALCZ data capture platform.

FAQ

What is the primary function of the AD9286-500EBZ?

The AD9286-500EBZ is an evaluation board for the AD9286 8-bit, 500 MSPS dual-channel ADC. It provides all necessary support circuitry-including power regulation, analog input conditioning (transformer or amplifier path), clock distribution, and LVDS/CMOS output buffering-to characterize the AD9286's dynamic performance under real-world conditions. The AD9286-500EBZ itself is not an IC but a fully assembled, tested PCB platform.

Does the AD9286-500EBZ include the AD9286 IC?

Yes, the AD9286-500EBZ evaluation board includes the AD9286 ADC mounted as the device under test (DUT). Figure 14 in the UG-191 user guide shows the AD9286 in its SG-MLF-7006 package (7 mm × 7 mm, 48-lead) with decoupling capacitors and associated biasing components. The board is shipped with the AD9286 pre-installed and ready for immediate evaluation.

What software tools are required to operate the AD9286-500EBZ?

Two primary software tools are required: VisualAnalog for FFT-based performance analysis and test template execution, and SPIController for low-level register configuration of the AD9286 via SPI. Both tools interface with the HSC-ADC-EVALCZ FPGA-based data capture board, which connects to the AD9286-500EBZ via a 60-pin header and to the host PC via USB 2.0.

Can the AD9286-500EBZ operate without an external clock source?

Yes. The AD9286-500EBZ supports both external clock input (via SMA connector J501) and on-board oscillator options. The default clock path uses a transformer-coupled circuit (T501) for single-ended sine wave inputs, but an optional crystal oscillator (Y505) can be installed for self-contained clock generation. Jumper J503 selects between these sources.

What are the power requirements for the AD9286-500EBZ?

The AD9286-500EBZ requires two independent 6 V, 2.5 A DC power supplies: one connected to J101 for the ADC board, and another connected to the HSC-ADC-EVALCZ board. On-board LDO regulators generate 1.8 V (AVDD/DRVDD), 3.3 V (clock/amp), and other bias rails. The supplied CUI EPS060250UH-PHP-SZ switching supplies meet these specifications.
