Analog Devices Inc. AD9204-65EBZ

Overview

AD9204-65EBZ from Analog Devices is a full-featured evaluation board designed to characterize the AD9204 10-bit, 65 MSPS dual-channel analog-to-digital converter (ADC) under real-world signal chain conditions. It supports transformer-coupled analog inputs up to ~150 MHz, SPI-based register configuration, and flexible clocking via on-board 65 MHz Valpey Fisher VFAC3-BHL-65MHz oscillator or external SMA input. The board enables high-fidelity ac performance testing including SNR, SFDR, and ENOB measurement.

For engineers reviewing the AD9204-65EBZ datasheet, AD9204-65EBZ pinout, AD9204-65EBZ application, or AD9204-65EBZ equivalent, this board delivers production-relevant ADC evaluation with VisualAnalog® and SPI Controller software integration, configurable power supply options (LDO or ADP2114 switching regulators), and support for HSC-ADC-EVALCZ FPGA data capture.

Technical Context

The AD9204-65EBZ implements a dual-channel, 10-bit, 65 MSPS ADC evaluation platform with differential analog input paths optimized for 50 Ω impedance and up to ~150 MHz bandwidth. It features transformer-coupled clock input (T601) with low-jitter signal conditioning and supports internal 1 V reference (2 V p-p full-scale range) per the AD9269 family specification.

Hardware configurability includes jumper-selectable SPI interface enablement (J302), oscillator enable (J605), power-down (J205), output enable (J205), and VREF mode selection (J201). Clocking options include on-board 65 MHz crystal oscillator, external SMA input (J602), or AD9517 LVPECL clock generator (U701) with SPI-programmable PLL.

FAQ

What is the primary function of the AD9204-65EBZ?

The AD9204-65EBZ is an evaluation board-not a semiconductor component-designed exclusively to assess the performance of the AD9204 10-bit, 65 MSPS dual-channel ADC. It provides all necessary support circuitry including clock generation, analog input conditioning, power regulation, SPI control interface, and CMOS output buffering. Engineers use the AD9204-65EBZ with VisualAnalog® and SPI Controller software to measure dynamic parameters such as SNR, SFDR, and ENOB under controlled lab conditions.

Which ADC does the AD9204-65EBZ evaluate?

The AD9204-65EBZ evaluates the AD9204 analog-to-digital converter-a dual-channel, 10-bit, 65 MSPS device belonging to the AD9269 family. As confirmed in UG-003 Table 1 and Figure 5, the board's default analog input network, VREF configuration (1 V internal reference, 2 V p-p full-scale), and clock architecture are specifically tuned for the AD9204 and its family members (AD9251, AD9231, AD9269, AD6659).

Does the AD9204-65EBZ include an on-board clock source?

Yes-the AD9204-65EBZ includes a Valpey Fisher VFAC3-BHL-65MHz crystal oscillator (Y601) as its default clock source, selected to match the AD9204's rated 65 MSPS sampling rate. The oscillator connects to the ADC clock inputs via transformer T601 and can be enabled using jumper J605. An external clock may be substituted via SMA connector J602 when J605 is removed.

How is the AD9204-65EBZ powered?

The AD9204-65EBZ ships with a CUI EPS060250UH-PHP-SZ 6 V, 2.5 A switching power supply connected to header P101. Internally, it uses low-dropout linear regulators (LDOs) to generate 1.8 V for AVDD/DRVDD and DVDD rails. Optional configurations support external bench supplies or replacement with ADP2114 switching regulators for improved power efficiency during ADC evaluation.

What software tools are required to operate the AD9204-65EBZ?

Two software tools are mandatory: VisualAnalog® for FFT-based ac performance analysis (SNR, SFDR, harmonic distortion) and SPI Controller for register-level configuration of the AD9204 (clock dividers, test modes, output formats). Both tools are provided free by Analog Devices and integrate directly with the AD9204-65EBZ via USB-connected HSC-ADC-EVALCZ FPGA capture board.
