AD9084-FMCA-EBZ (Apollo)

Overview

The EVAL-AD9084 is an FMC radio card for the AD9084, mixed signal front end (MxFE®), highly integrated device with a 16-bit, 28 GSPS maximum sample rate, RF digital-to-analog converter (DAC) core, and 12-bit, 20 GSPS maximum sample rate, RF analog-to-digital converter (ADC) core. The AD9084 supports four transmit channels and four receive channels.

The AD9084 is well suited for applications requiring both wideband ADCs and DACs to process signal(s) having wide instantaneous bandwidth. The device features a 48 lane, 32.5 Gbps JESD204C or 20 Gbps JESD204B data transceiver port, an on-chip clock multiplier, and a digital signal processing (DSP) capability targeted at either wideband or multiband, direct to RF applications.

The AD9084 also features a bypass mode that allows the full bandwidth capability of the ADC and/or DAC cores to bypass the DSP data-paths. The device also features low latency loopback and frequency hopping modes targeted at phased array radar systems and electronic warfare applications.

Features:

• Reconfigurable mixed signal platform design

• 4 16-bit RF DACs and 4 12-bit RF ADCs (4T4R)

• Programmable fractional data rate resampler from 1× to 2×

• JESD204B and JESD204C: 20Gbps and 28.21Gbps

• On-chip temperature monitoring unit

• Package: 24mm × 26mm, 899-ball BGA with 0.8mm pitch

Applications:

• Wireless communications test (5G mmWave, 5G C band, backhaul)

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 AD9084, we recommend to use the EVAL-AD9084 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.
