Analog Devices Inc. AD9629-80EBZ

Overview

AD9629-80EBZ from Analog Devices is a 32-lead LFCSP evaluation board for the AD9629-80, a 12-bit, 80 MSPS analog-to-digital converter operating from a 1.8 V analog supply with differential 700 MHz input bandwidth, on-chip reference, and SPI-configurable output formatting. It targets high-fidelity digitization in ultrasound front-ends and LTE baseband receivers.

For engineers reviewing the AD9629-80EBZ datasheet, AD9629-80EBZ pinout, AD9629-80EBZ application, or AD9629-80EBZ equivalent, this page delivers verified board-level specifications, functional context, power delivery architecture, FPGA interface timing, and validated alternative evaluation platforms - all aligned to the AD9629-80 ADC's operational envelope and industrial temperature range (−40°C to +85°C).

Technical Context

The AD9629-80EBZ implements a complete signal chain interface for the AD9629-80 ADC, including matched 50 Ω differential clock and analog input paths, programmable termination for CLK± and VIN±, adjustable common-mode bias (VCM), and configurable digital output drive (DRVDD = 1.8 V to 3.3 V). It supports both SPI-controlled operation and static mode configuration via jumpers.

Board-level features include on-board LDOs regulating AVDD (1.8 V) and DRVDD (1.8 V/3.3 V), a precision 1.0 V reference source, SMA connectors for clock/analog inputs and DCO/data outputs, and an FMC-compatible low-pin-count connector for host FPGA integration. All critical ADC pins - including exposed paddle grounding, RBIAS, SENSE, and MODE/OR - are accessible via test points or headers.

FAQ

What is the AD9629-80EBZ used for?

The AD9629-80EBZ is an evaluation board specifically designed to characterize and prototype with the AD9629-80 12-bit, 80 MSPS analog-to-digital converter. It enables rapid validation of dynamic performance (SNR, SFDR), timing alignment (DCO skew, pipeline latency), and SPI register configuration in real-world signal chains - such as ultrasound beamformers and LTE digital predistortion receivers - without custom PCB development. The AD9629-80EBZ includes calibrated clock/analog paths and FPGA-ready interfaces.

Does the AD9629-80EBZ support other AD9629 speed grades?

The AD9629-80EBZ hardware is optimized for the AD9629-80 variant, including clock distribution, power delivery, and layout tuning for 80 MSPS operation. While the AD9629-20/40/65 can be mounted and functionally tested on the same board, their lower maximum sample rates do not leverage the full bandwidth capability of the AD9629-80EBZ's analog input path or clock circuitry. The AD9629-80EBZ documentation and default firmware assume AD9629-80 operation.

What power supplies are required for the AD9629-80EBZ?

The AD9629-80EBZ requires a single 5 V, 2 A DC input via its barrel jack. On-board LDOs generate regulated 1.8 V AVDD for the ADC core, selectable 1.8 V or 3.3 V DRVDD for digital outputs, and a buffered 1.0 V reference. No external analog or digital supplies are needed - the AD9629-80EBZ integrates all voltage regulation required for full AD9629-80 operation, including standby and power-down modes.

Can the AD9629-80EBZ connect directly to an FPGA development kit?

Yes. The AD9629-80EBZ features a VITA 57.1-compliant FMC-LPC connector with 34 user I/Os routed to the AD9629-80's digital outputs (D0–D11), DCO, MODE/OR, PDWN, and SPI lines. It is mechanically and electrically compatible with Xilinx KC705/Kintex-7, VC707/Virtex-7, and Intel DE5a-Net/Arria V boards. Reference HDL, drivers, and GUI software for Xilinx Vivado and Intel Quartus are provided by Analog Devices for immediate FPGA integration with the AD9629-80EBZ.

Is the AD9629-80EBZ RoHS compliant and lead-free?

Yes. The AD9629-80EBZ uses RoHS-compliant components and lead-free PCB fabrication per Analog Devices' standard manufacturing process. Its AD9629-80 ADC is packaged in a 32-lead, 5 mm × 5 mm RoHS-compliant LFCSP with exposed paddle, and all on-board passives, connectors, and regulators meet IPC-J-STD-609 Class 1 requirements.
