Overview

The EVAL-ADMX100X-FMCZ is an evaluation board for the ADMX1001 and ADMX1002 ultra-low distortion, low-noise signal generator modules from Analog Devices. The EVAL-ADMX100X-FMCZ evaluation board provides the necessary interface circuitry to connect the ADMX100X module to a host PC via the SDP-H1 controller board, or alternatively via the SDP-S or SDP-B controller boards with the SDP-I-PMOD interposer.

The ADMX1001 and ADMX1002 modules are high-performance signal generators designed for applications requiring ultra-low harmonic distortion. The DPD algorithm exploits a patented differential temporal and amplitude sensing method that requires no external reference inputs, enabling exceptional signal purity through self-sensing correction. The ADMX1001 and ADMX1002 are capable of generating signals up to 40 kHz without Digital Pre-Distortion (DPD), or up to 20 kHz with DPD enabled, achieving −130 dBc typical Total Harmonic Distortion (THD) at 1 kHz.

The ADMX1001 uniquely includes a differential input acquisition channel to measure a signal of choice, while the ADMX1002 focuses solely on signal generation.

Features:

  • SPI and ATE communication interface

  • On-board power supply regulation

  • External common-mode voltage option

  • Sync In and Sync Out for coherent sampling

  • External output clamp voltage option

  • Differential to single-ended conversion

Applications:

  • Audio test and measurement

  • Automated test equipment (ATE)

  • Coherent sampling and ADC evaluation

  • Ultra-low distortion signal generation

  • Laboratory signal source

Recommendations

People who follow the flow that is outlined, have a much better experience with things. However, like many things, documentation is never as complete as it should be. If you have any questions, feel free to ask on our EngineerZone forums, but before that, please make sure you read our documentation thoroughly.

To better understand the ADMX1001 / ADMX1002, we recommend to use the EVAL-ADMX100X-FMCZ evaluation board.

Warning

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
