Analog Devices Inc. AD9269-20EBZ

Overview

AD9269-20EBZ from Analog Devices is a full-featured evaluation board designed to characterize and validate the AD9269 16-bit, 20 MSPS analog-to-digital converter (ADC) under real-world signal chain conditions. It supports transformer-coupled analog input up to ~150 MHz, internal 1 V reference (2 V_p-p full-scale), and clocking via on-board 50/65/80 MHz Valpey Fisher oscillator or external SMA input.

For engineers reviewing the AD9269-20EBZ datasheet, AD9269-20EBZ pinout, AD9269-20EBZ application, or AD9269-20EBZ equivalent, this board enables rapid validation of ADC performance metrics-including SNR, SFDR, and ENOB-using VisualAnalog® and SPI Controller software with HSC-ADC-EVALCZ FPGA capture hardware.

Technical Context

The AD9269-20EBZ implements a dual-channel, 16-bit, 20 MSPS ADC evaluation platform with configurable analog front-end options including balun-coupled inputs, optional AD8375 DVGA on Channel A, and ADL5562 amplifier support on Channel B. It provides both LDO- and ADP2114 switching-regulator power supply configurations for AVDD/DRVDD rails.

Its clock architecture supports three modes: on-board crystal oscillator (50/65/80 MHz), external single-ended sine wave via SMA J602, or differential LVPECL output from AD9517 clock generator. The board uses CMOS digital outputs buffered through U801/U802 and routed to P903/P902 for FPGA capture.

FAQ

What is the primary function of the AD9269-20EBZ?

The AD9269-20EBZ is an evaluation board-not a semiconductor component-that enables functional verification and AC performance characterization of the AD9269 16-bit, 20 MSPS dual-channel ADC. It provides all necessary support circuitry, clocking options, power regulation, analog input conditioning, and digital interface routing to validate the AD9269 in system-relevant configurations before integration into end equipment.

Does the AD9269-20EBZ support external clock sources?

Yes, the AD9269-20EBZ supports external clock sources via SMA connector J602 (labeled ENCODE+). When jumper J605 is removed, the on-board Valpey Fisher oscillator is disabled, allowing a clean 50 Ω-terminated sine wave (typically ~2.8 V_p-p or 13 dBm) to drive the ADC clock input through the transformer-coupled path. This mode is essential for jitter-sensitive measurements or custom clock tree validation.

Can the AD9269-20EBZ be used with other ADCs besides the AD9269?

Yes-the AD9269-20EBZ is part of a shared evaluation platform covering the AD9269 family, which explicitly includes the AD9251, AD9231, AD9204, and AD6659 according to UG-003 Table 1. While hardware layout and default jumper settings are optimized for the AD9269, the board's schematic and documentation confirm compatibility across this group of pin-compatible, functionally aligned 16-bit ADCs with similar reference, power, and interface requirements.

What software tools are required to operate the AD9269-20EBZ?

Two primary software tools are required: VisualAnalog® for FFT-based performance analysis (SNR, SFDR, harmonic distortion) and SPI Controller for register-level configuration of the AD9269. Both are provided free by Analog Devices and integrate with the HSC-ADC-EVALCZ FPGA capture board. Configuration files must match the target ADC (e.g., AD9269-specific .cfg file) to ensure correct register mapping and feature enablement.

How is power delivered to the AD9269-20EBZ and its DUT?

The AD9269-20EBZ ships with a 6 V, 2.5 A wall-mount switching power supply (CUI EPS060250UH-PHP-SZ) connected via P101. On-board LDOs generate 1.8 V for AVDD/DRVDD and DVDD rails by default. For higher efficiency, users can reconfigure the board to use the ADP2114 dual buck regulator instead-requiring specific resistor, capacitor, inductor, and jumper changes documented in UG-003 Pages 7 and 27–28.
