XILINX ANALOG MIXED SIGNAL TECHNOLOGY:
ANALOG CUSTOMIZATION BUILT INTO ALL
PROGRAMMABLE DEVICES
Xilinx AMS: Analog Integration
with Digital Customization
• Power of programmability for flexibility, ease
of integration, and reliability advantages
• Scalable analog sampling and signalprocessing performance
• Cost and size advantages with integrated
analog-to-digital converters
• Broadly applicable and customizable
analog measuring and signal conditioning
• Improve measurements in the digital
domain from on-chip filtering, calibration,
oversampling, and linearization
Analog Mixed Signal Overview
Xilinx’s® Analog Mixed Signal (AMS) technology lets developers replace complex analog
signal conditioning and discrete analog-to-digital converter (ADC) designs with a digitally
customizable analog interface and programmable logic. Built into all Xilinx 7 series FPGAs
and Zynq™-7000 SoC Platforms, AMS technology delivers the industry’s most flexible
general-purpose platform for discrete ADC designs. The on-chip solution boosts reliability,
safety and security and significantly lowers bill of material (BOM) costs by eliminating the
need for a diverse catalog of analog devices.
The combination of Xilinx AMS technology and All Programmable FPGA logic facilitates
customization for highly diverse applications ranging from simple system monitoring to more
signal-processing-intensive tasks such as linearization, calibration or filtering. The signalprocessing capabilities of Xilinx devices can also be leveraged to enhance ADC performance
with techniques like oversampling.

AMS Technology Evaluation
Platforms
AMS101 Evaluati o n Car d
The AMS technology can also be evaluated
with a pair of ISE® and Vivado™ design suite
tools, ChipScope™ Pro and the XADC
Wizard. These tools allow for convenient
system monitoring and let you quickly
instantiate the XADC in your design today.
Designers can fully exercise AMS
technology using the Xilinx AMS 101
Evaluation Card, which is included with the
following Xilinx kits: Zynq ZC702, Artix™-7
AC 701, Kintex™-7 KC 705 and
Virtex®-7 VC707.

Analog Measurements
To simplify evaluation, designers can leverage the AMS Evaluator tool for analog data capture and analysis using LabView. The AMS Evaluator
offers a wide range of measurement options: time or frequency domain, linearity, ADC registers, sensor data, DAC settings, decimation,
simultaneous sampling, sample rate, and input channel settings (single-ended or differential; unipolar or bipolar).
