Analog Devices Inc. EVAL-AD7960FMCZ

Overview

EVAL-AD7960FMCZ from Analog Devices is a full-featured FMC-form-factor evaluation board for the AD7960 18-bit, 5 MSPS differential SAR ADC. It integrates on-board ADR4520/4540/4550 voltage references (2.048 V/4.096 V/5.0 V), ADA4899-1/ADA4897-1 signal conditioning amplifiers, AD8031 reference buffers, and ADP7102/ADP7104/ADP124/ADP2300 power regulators - enabling low-noise analog signal acquisition and LVDS-based high-speed data capture in lab and system validation environments.

For engineers reviewing the EVAL-AD7960FMCZ datasheet, EVAL-AD7960FMCZ pinout, EVAL-AD7960FMCZ application, or EVAL-AD7960FMCZ equivalent, this page delivers verified hardware interface details, reference configuration options, software-controlled FFT/histogram analysis capabilities, SDP-compatible USB host control, and FMC-LPC (VITA 57) mechanical and electrical integration guidance - all specific to the EVAL-AD7960FMCZ board's role as an AD7960 evaluation platform.

Technical Context

The EVAL-AD7960FMCZ interfaces exclusively with the EVAL-SDP-CH1Z system demonstration platform via a 160-pin FMC-LPC connector (VITA 57 compliant), supporting echo-clocked LVDS communication using D±, CLK±, and DCO± pairs at up to 5 MSPS. It provides three selectable on-board reference voltages (2.048 V, 4.096 V, 5.0 V) routed through solder links LK7 and JP7, and supports both single-ended and fully differential analog input paths via configurable jumpers JP1–JP5 and amplifier options (ADA4899-1, ADA4897-1, or ADA4932-1).

Power is derived from +12 V supplied through the FMC connector: ADP7102 generates +7 V for amplifier +VS and reference ICs; ADP7104 supplies +5 V for VDD1 and regulators; ADP2300 produces −2.5 V for amplifier −VS; and ADP124 delivers 1.8 V for VDD2/VIO of the AD7960. All supplies are decoupled with ceramic capacitors placed near each device per layout guidelines.

FAQ

What is the primary function of the EVAL-AD7960FMCZ?

The EVAL-AD7960FMCZ is a dedicated evaluation board for the AD7960 18-bit, 5 MSPS differential SAR ADC. It provides complete signal conditioning, reference selection, power regulation, and LVDS data capture infrastructure - allowing engineers to characterize dynamic performance (SNR, SINAD, THD, SFDR) and DC accuracy (INL, DNL) without custom hardware. The EVAL-AD7960FMCZ enables rapid prototyping and system-level verification of high-fidelity data acquisition circuits.

Which system demonstration platform is required to operate the EVAL-AD7960FMCZ?

The EVAL-AD7960FMCZ requires the EVAL-SDP-CH1Z system demonstration platform for operation. It connects via a 160-pin FMC-LPC (VITA 57) interface and relies on the SDP's Spartan-6 FPGA, Blackfin processor, and LVDS transceivers to manage timing, control, and data transfer. No standalone operation is supported - the EVAL-AD7960FMCZ is not a self-contained module and must be used with the EVAL-SDP-CH1Z.

How are reference voltage options configured on the EVAL-AD7960FMCZ?

Reference selection on the EVAL-AD7960FMCZ is controlled by physical solder links: JP7 selects between GND and the 2.048 V ADR4520 output, while LK7 routes either the 4.096 V ADR4540 or 5.0 V ADR4550 output to the AD8031 reference buffer. These settings determine the REFIN voltage applied to the AD7960, and corresponding EN1/EN0 bits must be set in software to match the hardware configuration. All three references are buffered and decoupled per AD7960 data sheet requirements.

Does the EVAL-AD7960FMCZ support differential or single-ended analog inputs?

Yes - the EVAL-AD7960FMCZ supports both configurations via jumper-selectable signal paths. By default, JP1/JP2 and JP3/JP4 are set to B-to-center, routing signals through ADA4899-1/ADA4897-1 unity-gain buffers for single-ended or pseudo-differential use. Setting JP1/JP2 and JP3/JP4 to A-to-center configures the ADA4932-1 differential amplifier for true fully differential input, enabling optimal common-mode rejection and noise immunity when evaluating the AD7960's differential architecture.

What software tools are provided for the EVAL-AD7960FMCZ?

Analog Devices provides the AD7960_61 Evaluation Software, a Windows-based application that controls the EVAL-AD7960FMCZ via the EVAL-SDP-CH1Z. It offers real-time waveform capture, DC/AC histogram analysis, FFT-based spectral measurements (SNR, SINAD, THD, SFDR), and a consolidated Summary tab. The software supports adjustable sampling rates (500 kSPS to 5 MSPS), up to 131,072 samples per capture, and exports data to CSV for post-processing - all validated specifically for the EVAL-AD7960FMCZ hardware configuration.
