EVAL-AD9656

Quad, 16-Bit, 125 MSPS, Serial Output ADC with JESD204B Interface.

Overview

The EVAL-AD9656, is a FMC evaluation board for the AD9656, a quad, 16-bit, 125 MSPS serial output analog-to-digital converter (ADC) with JESD204B interface. The AD9656 is designed for low power, small size, and ease of use, and features a multistage, differential pipelined architecture with integrated output error correction logic.

Features:

• SPI interface for setup and control

• External, on-board 125 MHz crystal oscillator

• On-board LDO regulator, needing a single external 6V, 2A dc supply

• ADC VREF configurable for ADC-internal reference, on-board reference, off-board reference

• JESD204B serial output interface

• VisualAnalog and SPIController software interfaces

Applications:

• Communications

• Instrumentation and measurement

• Medical imaging

• Phased array radar

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, check the Help and Support section at the bottom of the page.

To better understand the AD9656, we recommend to use the EVAL-AD9656 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.
