Analog Devices Inc. EVAL-ADAQ23875FMCZ

Overview

EVAL-ADAQ23875FMCZ from Analog Devices is a fully featured FMC-form-factor evaluation board designed to simplify characterization of the ADAQ23875 16-bit, 15 MSPS µModule data acquisition system. It integrates on-board power generation (±7 V, +5 V, +2.5 V, −2 V), dual reference options (4.096 V LTC6655 or 2.048 V ADR4520), analog signal conditioning (ADA4899-1 amplifiers and ADG774 multiplexer), and high-speed digital interface via SDP-H1 controller for time/frequency domain analysis.

For engineers reviewing the EVAL-ADAQ23875FMCZ datasheet, EVAL-ADAQ23875FMCZ pinout, EVAL-ADAQ23875FMCZ application, or EVAL-ADAQ23875FMCZ equivalent, this page provides verified hardware configuration details, ACE software integration guidance, FMC-LPC interface mapping, jumper-based signal path selection (direct/amp/mux), and dynamic performance test setup for FFT, INL/DNL, and waveform capture - all specific to the factory-configured EVAL-ADAQ23875FMCZ board.

Technical Context

The EVAL-ADAQ23875FMCZ implements an FMC-LPC compliant interface with a 160-pin connector (P5) supporting differential LVDS (DA±/DB±), single-ended LVCMOS, SPI, I²C (SCL/SDA), and FPGA-controlled signals (CNV±, CLK±, DCO±). It routes the ADAQ23875's native 15 MSPS SAR ADC output through configurable two-lane or single-lane digital paths controlled by jumper P1.

On-board power architecture uses LTM8049 (dual-output µModule), ADP7118-2.5, ADP7183, and LT3023 to generate all required rails (+7 V, −2 V, +5 V, +2.5 V, +3.3 V) with local ceramic decoupling. Analog input path supports fully differential or single-ended configurations via SMA connectors (VIN+/VIN−), with optional gain/attenuation scaling and midscale VCMO (2.048 V) buffering per ADAQ23875 specification.

FAQ

What is the primary function of the EVAL-ADAQ23875FMCZ evaluation board?

The EVAL-ADAQ23875FMCZ evaluation board is a complete hardware and software platform designed exclusively to evaluate the ADAQ23875 16-bit, 15 MSPS µModule data acquisition solution. It provides all necessary power, reference, signal conditioning, and digital interface circuitry - including FMC-LPC connectivity to the SDP-H1 controller - enabling immediate time-domain and frequency-domain performance characterization of the ADAQ23875 without custom PCB development. The EVAL-ADAQ23875FMCZ supports both direct analog input and optional amplifier/multiplexer signal paths.

Which controller board is required to operate the EVAL-ADAQ23875FMCZ?

The EVAL-ADAQ23875FMCZ requires the SDP-H1 (EVAL-SDP-CH1Z) system demonstration platform controller board for operation. The SDP-H1 provides USB 2.0 host connectivity, FPGA-based data capture and control logic (Xilinx Spartan-6 + Blackfin ADSP-BF527), and the 160-pin FMC-LPC interface that mates directly with the EVAL-ADAQ23875FMCZ's P5 connector. No other controller board is supported - the EVAL-ADAQ23875FMCZ is not standalone and relies entirely on SDP-H1 for power, clock distribution, and data transfer.

How does the EVAL-ADAQ23875FMCZ handle analog input configuration?

The EVAL-ADAQ23875FMCZ supports three analog input configurations via hardware jumpers and onboard components: (1) Direct connection from SMA inputs (VIN+/VIN−) to the ADAQ23875, (2) Amplified path using ADA4899-1 op-amps (A2/A3) in unity-gain mode, and (3) Multiplexed path via ADG774 CMOS switch before the ADAQ23875. Jumper settings (JP5/JP6) select power source for amplifiers, while default factory configuration delivers 4.096 V reference and 2.048 V buffered VCMO to the ADAQ23875, enabling immediate differential input testing.

What software is needed to analyze data captured using the EVAL-ADAQ23875FMCZ?

Data analysis for the EVAL-ADAQ23875FMCZ requires Analog Devices' ACE (Analysis, Control, Evaluation) software with the dedicated EVAL-ADAQ23875FMCZ plug-in. ACE provides real-time waveform display, histogram, FFT (with oversampling up to 256×), and INL/DNL linearity analysis. The software communicates with the EVAL-ADAQ23875FMCZ via the SDP-H1 controller and requires installation of the SDP-H1 driver - both included in the ACE installer. No third-party or generic tools are supported for full feature access.

Can the EVAL-ADAQ23875FMCZ be powered independently of the SDP-H1 board?

Yes - the EVAL-ADAQ23875FMCZ can be powered independently using an external 3.3 V supply applied via the JP9 solder link (center-to-B default; change to center-to-A for external supply). However, all analog and digital supply rails (+7 V, −2 V, +5 V, +2.5 V) remain generated internally by the board's LTM8049, ADP7118, ADP7183, and LT3023 regulators. External powering only replaces the SDP-H1's +3.3 V rail; the SDP-H1 controller board is still mandatory for digital communication, clocking, and data capture functionality.
