Analog Devices Inc. AD9269-65EBZ

Overview

AD9269-65EBZ from Analog Devices is a full-featured evaluation board designed to characterize the AD9269 16-bit, 65 MSPS analog-to-digital converter under real-world signal chain conditions. It supports transformer-coupled differential analog input up to ~150 MHz, on-board 65 MHz Valpey Fisher VFAC3-BHL-65MHz oscillator clocking, and SPI-based configuration via VisualAnalog and SPI Controller software.

For engineers reviewing the AD9269-65EBZ datasheet, AD9269-65EBZ pinout, AD9269-65EBZ application, or AD9269-65EBZ equivalent, this board enables high-fidelity AC performance validation-including SNR, SFDR, and ENOB-using clean low-jitter signal sources, configurable power domains (LDO or ADP2114 switching), and FPGA-based data capture with the HSC-ADC-EVALCZ platform.

Technical Context

The AD9269-65EBZ implements a dual-channel, 16-bit, 65 MSPS ADC evaluation interface with transformer-coupled analog inputs (50 Ω, 2 V p-p full-scale), internal 1.0 V reference, and default 65 MHz crystal oscillator (VFAC3-BHL-65MHz). It supports both CMOS digital outputs and optional LVPECL clocking via AD9517.

Power delivery includes selectable LDO regulation (default) or ADP2114 synchronous buck converters for AVDD/DRVDD rails; jumper-configurable modes include SPI control, non-SPI operation, PDWN/OE enable, and external vs. internal reference selection.

FAQ

What is the primary function of the AD9269-65EBZ?

The AD9269-65EBZ is an evaluation board-not a semiconductor component-that enables functional and AC performance characterization of the AD9269 16-bit, 65 MSPS dual-channel analog-to-digital converter. It provides all necessary support circuitry including clock generation, analog input conditioning, power regulation, SPI interface, and CMOS output buffering for connection to the HSC-ADC-EVALCZ FPGA capture platform.

Does the AD9269-65EBZ support other ADCs besides the AD9269?

Yes-the AD9269-65EBZ is part of a shared evaluation platform supporting the entire AD9269 family: AD9251, AD9231, AD9204, AD9269, and AD6659. All share identical default analog input configuration (Figure 5), 1.0 V internal reference, and 65 MHz oscillator option, though individual device specifications (e.g., resolution, speed, power) differ per datasheet.

What clock options are available on the AD9269-65EBZ?

The AD9269-65EBZ offers three clocking paths: (1) default on-board 65 MHz Valpey Fisher VFAC3-BHL-65MHz oscillator (enabled via J605), (2) external single-ended 50 Ω sine wave input at SMA connector J602 (ENCODE+), and (3) optional AD9517 LVPECL clock generator (U701) configured via SPI, requiring resistor population per UG-003 Section 6.

Can the AD9269-65EBZ be powered by bench supplies instead of the included wall adapter?

Yes-AD9269-65EBZ supports external bench power via P102 and P103 headers. Users must remove ferrite beads E101/E102/E114/E103/E105/E107 to isolate on-board LDOs, then supply 1.8 V @ 1 A for DUT_AVDD/DRVDD, 1.8 V @ 1 A for DVDD, and optionally 3.3 V @ 1 A for clock circuitry and amplifier bias rails (5V_AMPVDD/3V_AMPVDD).

Is the AD9269-65EBZ compatible with VisualAnalog and SPI Controller software?

Yes-AD9269-65EBZ is fully supported by Analog Devices' VisualAnalog® (for FFT analysis, SNR/SFDR measurement, and data visualization) and SPI Controller software (for register-level configuration of the AD9269's sampling mode, data format, clock divider, and power-down settings), both available free at analog.com/fifo.
