EVALUATION BOARD SOFTWARE QUICK START PROCEDURES

INSTALLING THE ACE SOFTWARE AND ADL5580

PLUG-INS

The ADL5580-EVALZ evaluation board connects to the SDP-S

for quick evaluation of the ADL5580. The ADL5580-EVALZ is

configured over the USB from a panel within the ACE software,

which can be downloaded from the ACE software page. When

the ACE software installation is complete, the user must install

the ACE Evaluation Board Plug-ins that are provided with the

evaluation package to the hard drive of the PC.

Double-click the Board.ADL5580.1.2019.22300.acezip file to

install the evaluation board plug-ins.

Ensure that the Board.ADL5580.1.2019.22300 and Chip.

ADL5580.1.2019.22300 folders are located in the

C:\ProgramData\Analog Devices\ACE\Plugins folder.

SINGLE-TONE DEMONSTRATION WITH ACE

Use the following settings to configure the ADL5580 to amplify

a 100 MHz sine wave using the ACE software:

•Configure the hardware according to the Hardware Setup

section and what is shown in Figure 5.

•Set the frequency of the signal generator to 100 MHz and

the output level to −20 dBm. Optionally, connect the

spectrum analyzer to the J3 and J4 connectors using an

external balun (for example, the HYPERLABS 2:1 balun

was used).

•Set RF off state.

•Use 2.92 mm, 40 GHz, female Southwest Microwave

connectors at J1, J2, J3, and J4 on the ADL5580-EVALZ.

Connect these connectors to the Subminiature Version A

(SMA), 3.5 mm connector with care. However, it is

suggested to use a 2.92 mm, SMA adaptor to avoid any

potential damage.

•Power up the ADL5580-EVA L Z .

•Launch the ACE application. This action displays the

initial ACE start page as shown in Figure 6. The ADL5580-

EVALZ is detected automatically and displays under

Attached Hardware.

•Click the ADL5580-E VA L Z icon to open the evaluation

board level view shown in Figure 7. Because the ADL5580-

EVALZ is a simple evaluation board, only the ADL5580

represents as a controllable component.

•Click the ADL5580 icon to open the IC level view as

shown in Figure 8.

•Configure the ADL5580 in the ChipView (see Figure 7) as

follows:

•Select the Pin 19 check box to select EN.

•Ensure that the Enable Ref and the Enable Amp

check boxes are selected. Enable Ref enables the

internal voltage, and Enable Amp enables the

amplifier section (see Figure 8).

•Under the Input Termination Mode dropdown

menu, select Internal VCM Enabled, VCMI Pin

Disconnected (see Figure 8).

•Under the Output Termination Mode dropdown

menu, select Internal VCM Enabled, VCMO Pin

Disconnected (see Figure 8).

•Set C Peak (defaults to 3), if necessary (see Figure 8).

•Set Input CM Voltageand Output CM Voltage, if

necessary (see Figure 8).

•Click Apply Changes for the changes to take effect (see

Figure 8). Repeat the previous step to enable or disable the

ADL5580-EVA LZ with the hardware enabled.

•Set RF on state at the signal generator.

•With the signal generator set to an output level of −20 dBm,

the power gain is 13 dB at 1 GHz. However, note that this

value is affected by cabling and balun losses on the signal

path.

USING THE ADL5580-EVALZ EVALUATION BOARD

LOSSES AND SIGNAL-TO-NOISE RATIO (SNR)

DEGRADATION

The ADL5580 provides a nominal 10 dB of voltage gain defined

between the input and output pins, which translates to a power

gain of 13 dB because the input impedance is twice the output

impedance. The resistive impedance matching converts the

50 Ω differential output to a more common 100 Ω. However,

this resistive impedance matching adds 7.7 dB of attenuation

that must be considered. The miscellaneous components of the

ADL5580-EVALZ can add to the signal losses and degrade the SNR

as well.

ACE MACRO TOOLS

ACE also contains Macro Tools that can record register reads and

writes. Use the Installation Wizard or click Proceed to Memory

Map to use these tools. To use the M a cr o To o l s , select the Record

Sub-Commands checkbox and click the Record button (see

Figure 10). Changes in the memory map remain bolded until these

changes are applied to the device. The changes are also recorded as

user interface (UI) commands by the Macro Tools once the

changes are made. Changed register write commands for the

controls are also recorded. Click Apply Changes to execute the

commands and make changes to the memory map. To stop

recording, click the Stop Recording button. A M a cr o To o lspage

with the command steps is then created. The macro can be saved

using the Save Macro button so that the macro can be loaded

for future use.

The raw macro file is saved using ACE syntax, which is

not easily readable. To remedy this, the ACE software download

includes an ACE Macro/Hex Converter tool (see Figure 11). The

user can choose to include or exclude register write, reads, and/or

comments in the conversion. The file pathways for the source

and save paths are the same, except the source is an .acemacro

file, and the save is a .txt file. The Convert button (see Figure 11)

converts the macro to hex, which is easier to read, and the

conversion tool can also convert .txt files back to .acemacro files,

if desired.
