MAX2870/MAX2871 Evaluation

Kits

General Description

Features

The MAX2870/MAX2871 evaluation kits (EV kits) simplify

the testing and evaluation of the MAX2870 and MAX2871

ultra-wideband phase-locked loop (PLL) with integrated

voltage-control oscillators (VCOs). Each EV kit is fully

assembled and tested at the factory. Standard 50Ω SMA

connectors are included on the EV kits for the inputs

and outputs to enable quick and easy evaluation on the

test bench.

● Easy Evaluation of the MAX2870 and MAX2871

● 50Ω SMA Connectors

● All Critical Peripheral Components Included

● PC Control Software

● Proven PCB Layout

● Fully Assembled and Tested

This document provides a Quick Start guide, a

description of the EV kit circuit, a Troubleshooting Guide,

the circuit schematic, a list of components for the EV kit,

and diagrams for each layer of the PCB.

Ordering Information appears at end of data sheet.

Note: This EV kit data sheet supports the MAX2870 (Rev

B) and MAX2871 EV kits. Customers using MAX2870

(Rev A) EV kit can access the schematic, PCB layout, and

user guide under the Help menu of the EV kit software.

Software Installation and Evaluation Guide

Quick Start

1) Visit www.maximintegrated.com/evkitsoftware to

download the latest version of the EV kit software,

Max287X_Setup_1-1-x.zip.

Required Equipment

●

MAX2870/MAX2871 EV kit board

Mini-USB type A-to-type B cable (included)

User-supplied Windows PC

2) Extract the zip ﬁle and run the installation ﬁle.

Restart the PC after installation.

User-supplied spectrum analyzer or signal analyzer

3) Run the MAX287x.exe ﬁle. Choose the correct IC

type (MAX2870 or MAX2871) at the front page and

click the Continue button. The EV kit GUI appears

and looks similar to Figure 2.

Note: In the following sections, software-related items are

identified by bolding. Text in bold refers to items from the

EV kit software. Text in bold and underlined refers to

items from the Windows operating system.

4) Verify that USB Connected is displayed in green in

the lower right-hand corner of the GUI.

Procedure

5) Verify that the EV kit TCXO (U2) frequency matches

the EV kit software REF. FREQ. If not, enter the

correct value in MHz (default is 50) and press the

Enter key.

Hardware Connection Guide

Each EV kit is fully assembled and tested. Follow the

steps below to verify board operation:

1) Verify that all jumpers are in their default positions, as

shown in Figure 1.

6) In the GUI, click on the Defaults button and then the

Send All button located at the top of the GUI.

2) Connect the USB cable from the PC to the EV kit.

7) Enter the desired output frequency in MHz in the

RF_OUTA or RF_OUTB edit box and press the

Enter key.

3) Connect one of the RFOUT SMA connectors to a

signal analyzer or spectrum analyzer.

8) Verify that the PLL Lock indicator in the lower right-

4) Terminate the remaining unused RFOUT ports with a

hand corner of the GUI is displayed in green.

50Ω pad.

9) Use the signal analyzer to verify the performance of

the MAX2870 or MAX2871.

EE-Sim® PLL tool). Note: If the reference-source

phase noise is poor, it could impact the ICs’ output

phase noise.

Troubleshooting Guide

External Reference Source

The default on-board crystal oscillator frequency is

50MHz. To use a different reference frequency, perform

the following steps:

RF Output Level

There is a 3dB pad at each RFOUT port. The purpose of

these 3dB pads is to provide reasonable matched load

to the ICs’ outputs when unused. Therefore, direct power

measurement at the EV kit’s RF OUT SMA ports is 3dB

lower than the actual output level. To measure the true

output level, remove the 3dB pads and terminate all active

unused ports with a 50Ω load.

1) Remove jumper JP14 (disables on-board XTAL

oscillator).

2) Apply a reference signal to the REFIN SMA port,

(power > 0 dBm).

3) Update the REF. FREQ. value in the EV kit GUI .

4) Program the IC to the desired frequency.

5) Optional: It is recommended to measure the

reference-source phase noise and check the

Export/Import Full Register Settings

To export the full register settings from the MAX2870/

MAX2871, perform the following steps:

To import full register settings to the MAX2870/MAX2871,

perform the following steps:

● Copy the register settings (comma delimited) from a

text editor to the clipboard.

● Click on Reg → Clip in the lower left-hand corner

of the GUI. The registers are then saved to the clip-

board.

● Click on Clip → Reg in the lower left-hand corner of

the GUI.

● Paste the clipboard to any text editor.

● Click the Send All button in the top right-hand

corner of the GUI.
