Analog Devices Inc. ADL5580-EVALZ

Overview

ADL5580-EVALZ from Analog Devices is a fully differential, 10 GHz ADC driver evaluation board designed to characterize the ADL5580 RF amplifier under real-world conditions. It supports differential or single-ended input to differential output configurations, delivers fixed 10 dB gain, operates from +5 V and −1.8 V supplies, and enables high-fidelity signal conditioning for 12–16-bit ADCs in wideband receiver chains.

For engineers reviewing the ADL5580-EVALZ datasheet, ADL5580-EVALZ layout, ADL5580-EVALZ application notes, or ADL5580-EVALZ power sequencing requirements, this page provides verified board-level specifications, supply decoupling guidance, RF interface validation, and SPI-controlled programmability support for rapid prototyping of high-speed data acquisition systems.

Technical Context

The ADL5580-EVALZ implements the ADL5580 amplifier in a 4 mm × 4 mm, 20-terminal LGA package with full dc-coupled differential I/O, 100 Ω differential input impedance, and 50 Ω differential output impedance. It integrates on-board 100 pF/1 µF decoupling per supply rail, configurable common-mode voltage (VCMI/VCMO) termination via jumpers or register control, and 3-wire SPI (CS/SCLK/SDIO) for real-time gain peaking, enable/disable, and bias tuning.

Board-level design supports both ac- and dc-coupled operation, includes EN pin for hardware shutdown (20 ns enable / 6 ns disable), and maintains <2.26 nV/√Hz input-referred noise at 2 GHz while delivering −66 dBc HD2 and −88.1 dBc HD3 at 6 GHz - enabling direct drive of high-performance ADCs like the AD9213 without external matching networks.

FAQ

What is the primary purpose of the ADL5580-EVALZ?

The ADL5580-EVALZ is an evaluation board designed exclusively to validate and characterize the ADL5580 fully differential 10 GHz ADC driver IC. It provides all necessary supply decoupling, RF I/O interfaces (SMA), SPI programming access, and hardware enable control - enabling engineers to measure gain flatness, noise figure, harmonic distortion, and settling behavior across dc to 10 GHz without custom PCB development. The ADL5580-EVALZ directly supports bench testing of the ADL5580 in its native 20-pin LGA package.

Does the ADL5580-EVALZ support both ac-coupled and dc-coupled operation?

Yes, the ADL5580-EVALZ supports both ac- and dc-coupled configurations. For ac-coupling, the board includes 0.1 µF series capacitors on VINP, VINN, VOUTP, and VOUTN paths as shown in Figure 32 of the ADL5580 datasheet. For dc-coupling, those capacitors are omitted or bypassed, and the user must ensure input/output common-mode voltages remain within the ADL5580's specified ranges (VCMI = 1.7 V, VCMO = 0.5 V typical). The ADL5580-EVALZ provides jumper-accessible VCMI and VCMO nodes to facilitate either mode.

How is power sequencing handled on the ADL5580-EVALZ?

The ADL5580-EVALZ requires strict monotonic power sequencing: the −1.8 V (MAVEE) rail must be applied before or simultaneously with the +5.0 V (PAVCC) rail, with no glitches or reversals. This prevents internal digital logic latch-up. The board implements dedicated 100 pF + 1 µF decoupling per PAVCC and MAVEE pad (Pads 1/4 and 2/3), placed adjacent to the ADL5580 LGA footprint. Users must supply clean, low-noise lab supplies or use the recommended Analog Devices power modules to meet the ADL5580-EVALZ sequencing requirement.

Can the ADL5580-EVALZ be used to evaluate programmable features like CPEAK tuning?

Yes, the ADL5580-EVALZ exposes the full 3-wire SPI interface (CS, SCLK, SDIO) and supports register-level control of all programmable functions, including peaking control (PRG_CPEAK_1P8V in Register 0x101), common-mode setup modes (Register 0x100), and enable bits (EN_AMP_1P8V/EN_REF_1P8V). The board accepts 1.8 V or 3.3 V logic levels on SPI lines, and the ADL5580-EVALZ documentation includes register maps and timing diagrams aligned with Table 2 of the ADL5580 datasheet to verify CPEAK tuning impact on bandwidth flatness and harmonic suppression.

What RF measurement capabilities does the ADL5580-EVALZ enable out-of-the-box?

The ADL5580-EVALZ enables immediate S-parameter, noise figure, OIP3, HD2/HD3, and group delay measurements using standard lab equipment. It features 50 Ω SMA connectors on all RF ports (VINP, VINN, VOUTP, VOUTN), calibrated 100 Ω differential input impedance, and 50 Ω differential output impedance - eliminating need for external baluns or matching networks when interfacing with vector network analyzers or spectrum analyzers. The ADL5580-EVALZ also supports time-domain enable response testing via the EN pin (Pin 19) and marker-based pulse analysis as shown in Figure 24 of the ADL5580 datasheet.
