Analog Devices Inc. ADXBAND16EBZ

Overview

ADXBAND16EBZ from Analog Devices is an evaluation board for the AD9084 Apollo MxFE quad RF DAC/ADC, supporting 4T4R wideband signal processing with 28GSPS DAC and 20GSPS ADC sample rates, 18GHz analog bandwidth, JESD204C up to 28.21Gbps, and on-chip DDC/DUC for radar and mmWave 5G infrastructure applications.

For engineers reviewing the ADXBAND16EBZ datasheet, ADXBAND16EBZ pinout, ADXBAND16EBZ application, or ADXBAND16EBZ equivalent, this page delivers verified board-level specifications, supported device configuration (AD9084), interface compatibility (JESD204C, SPI, HSCI), thermal and power delivery design guidance, and OEM-ready supply support.

Technical Context

The ADXBAND16EBZ implements full-featured hardware validation of the AD9084 mixed-signal front-end, enabling simultaneous capture and generation of wideband RF signals across four independent transmit and receive channels. It integrates high-speed clock distribution, low-noise LDOs, temperature monitoring, and FPGA-based control logic for dynamic reconfiguration of DDC/DUC paths, NCO profiles, and loopback modes.

Board-level architecture supports direct RF sampling up to 18GHz on both ADC inputs and DAC outputs, with differential 50Ω interfaces, calibrated DC-coupled biasing, and programmable gain stages. It provides access to all 48 JESD204C lanes, dual SYSREF domains, and GPIO-triggered fast frequency hopping-critical for phased-array radar and electronic warfare test setups.

FAQ

What is the primary function of the ADXBAND16EBZ evaluation board?

The ADXBAND16EBZ is a fully featured evaluation platform for the AD9084 Apollo MxFE RF DAC/ADC. It enables hardware validation of 4T4R wideband signal chains, including JESD204C data streaming, real-time DDC/DUC processing, fast frequency hopping, and low-latency loopback modes. The ADXBAND16EBZ provides complete access to all AD9084 I/O, clocking, and control interfaces required for radar, EW, and mmWave 5G system development.

Does the ADXBAND16EBZ support both JESD204B and JESD204C protocols?

Yes, the ADXBAND16EBZ supports both JESD204B (up to 20 Gbps) and JESD204C (up to 28.21 Gbps) via configurable SERDES settings. It routes all 48 JESD204C lanes from the AD9084 to FPGA-based host interface logic, with selectable lane counts, subclass modes (0 or 1), and deterministic latency alignment-verified per UG-2300 and AD9084 Rev. D datasheet timing requirements.

Can the ADXBAND16EBZ be used for Ku-band (12–18 GHz) RF signal generation and analysis?

Yes, the ADXBAND16EBZ supports full AD9084 analog bandwidth up to 18 GHz on both DAC outputs and ADC inputs. Its differential 50Ω RF interfaces, calibrated bias networks, and matched PCB layout preserve signal integrity through Ku-band. Measured return loss ≥9 dB (Ku-band) and NSD down to −156 dBFS/Hz at 28 GSPS confirm validated performance for direct-RF mmWave applications using the ADXBAND16EBZ.

What software and firmware tools are provided with the ADXBAND16EBZ?

Analog Devices supplies the ADXBAND16EBZ with the ACE (Analog Circuit Evaluation) software suite, HDL reference designs for Xilinx Kintex Ultrascale+ FPGAs, Python-based API libraries, and UG-2300 Device User Guide. These tools enable full register-level control of the AD9084 via SPI/HSCI, real-time spectrum monitoring, DDC/DUC coefficient loading, and automated calibration sequences-all tested and validated on the ADXBAND16EBZ hardware platform.

Is thermal management integrated into the ADXBAND16EBZ design?

Yes, the ADXBAND16EBZ includes a thermally optimized layout with internal copper planes, thermal vias under the AD9084 BGA_ED package, and an onboard temperature sensor feeding the AD9084's on-chip monitoring unit. It supports continuous operation at full 28 GSPS/20 GSPS throughput with junction temperatures maintained within −40°C to +110°C, as confirmed by thermal imaging and power sweep tests documented in the AD9084 datasheet Rev.
