EVAL-AD9083

16-Channel, 125 MHz Bandwidth, Continuous Time Σ-Δ ADC.

Overview

The EVAL-AD9083 is an FMC evaluation card for the AD9083, a 16-channel, 125 MHz bandwidth, continuous time Σ-Δ (CTSD) ADC. The device features an on-chip, programmable, single-pole antialiasing filter and termination resistor designed for low power, small size, and ease of use.

Each of the 16 ADC cores features a first-order CTSD modulator architecture with integrated, background nonlinearity correction logic and self-cancelling dither. Each ADC has a signal processing tile to filter out-of-band shaped noise and reduce the sample rate, containing a cascaded integrator comb (CIC) filter and a quadrature digital downconverter (DDC) with multiple finite input response (FIR) decimation filters.

The serialized output uses a Subclass 1 JESD204B interface configurable in various lane configurations (up to four lanes). Multiple device synchronization is supported through the SYSREF±, TRIG±, and SYNCINB± input pins.

Features:

• 16-channel, 125 MHz bandwidth CTSD ADC

• Programmable single-pole antialiasing filter

• Programmable input termination resistor

• Integrated background nonlinearity correction and self-cancelling dither

• Signal processing tile per channel: CIC filter + quadrature DDC + FIR

• JESD204B interface, up to 4 lanes (Subclass 1)

• Multiple device synchronization (SYSREF±, TRIG±, SYNCINB±)

• 1.8 V SPI (3-wire) configuration interface

• Flexible power-down modes

• 100-ball CSP_BGA, −40°C to +85°C

Applications:

• Multi-channel instrumentation and data acquisition

• Phased array radar and electronic warfare

• Test and measurement equipment

• Communications receivers

• Medical imaging

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 AD9083, we recommend using the EVAL-AD9083 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.
