Analog Devices Inc. AD9680-1250EBZ

Overview

AD9680-1250EBZ from Analog Devices is an evaluation board designed specifically for the AD9680-1250 dual 14-bit, 1.25 GSPS analog-to-digital converter (ADC), supporting full-bandwidth operation with 2 GHz input bandwidth, JESD204B subclass 1 deterministic latency, and on-board balun-coupled RF inputs. It enables high-fidelity digitization of wideband signals in radar, electronic warfare, and communications test equipment.

For engineers reviewing the AD9680-1250EBZ datasheet, AD9680-1250EBZ pinout, AD9680-1250EBZ application, or AD9680-1250EBZ equivalent, this page delivers verified technical context, key specifications, availability details, manufacturer background, and targeted FAQs - all grounded in official Analog Devices documentation and evaluation kit resources.

Technical Context

The AD9680-1250EBZ implements a complete signal chain for the AD9680-1250 ADC, including wideband balun-driven differential analog inputs (P200/P202), low-jitter 1.25 GHz sample clock interface (J801), 625 MHz reference clock input (J804), and JESD204B v1.1 serial output routed to an FMC-compatible connector for FPGA capture. It supports both full-bandwidth mode (2 × 1.25 GSPS) and DDC-enabled modes (e.g., two NCOs with decimation-by-4).

Board-level features include SPI-controlled configuration via ACE or SPIController software, VisualAnalog® real-time FFT analysis, deterministic latency validation using subclass 1 JESD204B, and power delivery via 12 V/1 A and 3.3 V/3 A supplies from the ADS7-V2EBZ FPGA data capture board - eliminating need for external DC supplies.

FAQ

What is the primary function of the AD9680-1250EBZ?

The AD9680-1250EBZ is an evaluation board for the AD9680-1250 dual 14-bit, 1.25 GSPS analog-to-digital converter. Its purpose is to provide a fully configured, balun-coupled signal path - including clocking, power, JESD204B interface, and SPI control - enabling engineers to validate the ADC's performance in full-bandwidth and DDC-based RF sampling applications without custom hardware design.

Which FPGA data capture board is required to operate the AD9680-1250EBZ?

The AD9680-1250EBZ must be used with the ADS7-V2EBZ FPGA-based data capture board. This board provides the necessary JESD204B receiver logic, power delivery (12 V/1 A and 3.3 V/3 A via FMC), and USB 2.0 host interface. The obsolete ADS7-V1EBZ is explicitly not recommended for new evaluations involving the AD9680-1250EBZ.

Does the AD9680-1250EBZ support deterministic latency, and how is it validated?

Yes, the AD9680-1250EBZ supports deterministic latency through JESD204B subclass 1 operation. Validation is performed using provided SPIController scripts and the "Validating Subclass 1 Operation of the AD9680" guide, which demonstrates measurable latency consistency across power cycles and re-initializations - critical for phased-array radar and synchronized multi-channel systems using the AD9680-1250EBZ.

What software tools are officially supported for configuring and analyzing data from the AD9680-1250EBZ?

Analog Devices officially supports ACE (Analysis | Control | Evaluation), VisualAnalog®, and SPIController for the AD9680-1250EBZ. ACE provides GUI-based register configuration and FFT analysis; VisualAnalog enables real-time spectral visualization and signal processing; SPIController allows low-level register access and scripting for repeatable test sequences - all validated against the AD9680-1250EBZ hardware revision 9680CE04B.

Can the AD9680-1250EBZ be used to evaluate the AD9690 ADC?

Yes - per Analog Devices' official wiki, users evaluating the single-channel AD9690 should utilize Channel A on the AD9680-1250EBZ (or AD9680-1000EBZ). The AD9680-1250EBZ's hardware and software infrastructure fully supports isolated evaluation of Channel A, including independent clocking, SPI control, and JESD204B lane mapping - making it a functional proxy for AD9690 characterization when used per documented guidelines.
