Analog Devices Inc. AD9740-FMC-EBZ

Overview

AD9740-FMC-EBZ from Analog Devices is an FMC-compatible evaluation board designed to interface with the AD9740 14-bit, 210 MSPS TxDAC® digital-to-analog converter in LFCSP package. It supports transformer-coupled, resistor-terminated, and differential/single-ended analog output configurations, features on-board RSET adjustment for full-scale current tuning (2–20 mA), and integrates edge-triggered CMOS digital inputs operating up to 210 MSPS.

For engineers reviewing the AD9740-FMC-EBZ datasheet, AD9740-FMC-EBZ pinout, AD9740-FMC-EBZ application, or AD9740-FMC-EBZ equivalent, this page delivers verified hardware specifications, FMC-LPC interface details, supported clock modes (single-ended/PECL/differential), power-down control implementation, and real-world DAC evaluation setup guidance aligned with UG-1650 Rev. A.

Technical Context

The AD9740-FMC-EBZ implements the AD9740 DAC in a 32-lead LFCSP package with configurable clock input (CMODE-selectable single-ended, PECL, or high-Z differential), dual differential current outputs (IOUTA/IOUTB), and on-board RSET network for full-scale current calibration. It routes all 14 digital data lines, clock, sleep, and reference control signals to the FMC-LPC connector per ANSI/VITA 57.1.

This board pairs with the AD-DAC-FMC-ADP adapter and SDP-H1 controller to enable PC-based waveform generation via DPGDownloader software. It supports dc-coupled I-V conversion using external op amps or ac-coupled RF transformer output with optional RDIFF termination for 50 Ω system matching and VSWR optimization.

FAQ

What is the primary function of the AD9740-FMC-EBZ evaluation board?

The AD9740-FMC-EBZ evaluation board is a fully assembled, FMC-LPC compliant hardware platform that enables rapid characterization and integration of the AD9740 14-bit, 210 MSPS DAC. It provides direct access to all critical analog and digital interfaces-including IOUTA/IOUTB, CLK+, CLK−, CMODE, SLEEP, and REFIO-while supporting multiple output topologies (transformer, op amp, resistor-terminated) and full-scale current tuning via RSET. The AD9740-FMC-EBZ is not a standalone DAC but a validated test vehicle for system-level DAC performance verification.

Does the AD9740-FMC-EBZ include the AD9740 DAC IC onboard?

Yes, the AD9740-FMC-EBZ includes the AD9740 14-bit DAC in a 32-lead LFCSP package mounted directly on the board. It is pre-populated and soldered per UG-1650 Rev. A specifications, with optimized layout for high-frequency analog integrity, including dedicated ground planes, controlled-impedance routing for clock and data lines, and isolation between analog and digital sections. The AD9740-FMC-EBZ does not require additional DAC mounting-it ships ready for immediate connection to an FMC-compatible carrier.

Which host controller boards are compatible with the AD9740-FMC-EBZ?

The AD9740-FMC-EBZ is designed for use with FMC-LPC carrier boards compliant with ANSI/VITA 57.1, including the EVAL-SDP-CH1Z (SDP-H1) system demonstration platform. It requires the AD-DAC-FMC-ADP adapter board to bridge the FMC-LPC interface to the SDP-H1's 120-pin connector. When used with DPGDownloader software on Windows OS, the AD9740-FMC-EBZ enables full register control, waveform streaming, and real-time SFDR measurement-without requiring custom FPGA logic or driver development.

How is clock input configured on the AD9740-FMC-EBZ?

Clock input on the AD9740-FMC-EBZ is configured via the CMODE pin on the AD9740 IC, which selects among three modes: single-ended (CMODE tied to CLKCOM), PECL differential (CMODE tied to CLKVDD), or high-impedance differential (CMODE floating). The board provides test points and jumpers to set CMODE, and the internal PECL terminations (50 Ω each) are active in PECL mode. All modes support up to 210 MSPS update rates, and the AD9740-FMC-EBZ includes matched-length traces and SMA connectors for low-skew clock injection.

Can the AD9740-FMC-EBZ operate in power-down mode, and how is it activated?

Yes, the AD9740-FMC-EBZ supports hardware-controlled power-down mode via the SLEEP pin of the AD9740 DAC. Applying Logic High (≥ AVDD/2) to the SLEEP pin disables the current sources and reduces total power dissipation to approximately 15 mW at 3.3 V. The AD9740-FMC-EBZ provides a dedicated test point and jumper option for SLEEP control, and the DAC resumes full operation within ~5 μs after SLEEP is deasserted. This feature is fully implemented and verified per UG-1650 Rev. A timing requirements.
