Introduction
The Lime Development System is a comprehensive hardware and software combination that
allows users to evolve and refine a wireless sub-system. It can be combined with a baseband
processor such as an FPGA or DSP processor to develop a comprehensive wireless solution.
The EVB7 module is a high-speed wireless communication module, based on the LMS7002M
fully programmable RF transceiver. It is designed to support 2G, 3G, 4G/LTE radio systems
with both time-division duplex (TDD) and frequency-division duplex (FDD) applications, M2M
and software defined radios. The wireless communication module covers the frequency range of
100 kHz to 3.8 GHz, including licensed and unlicensed bands. The channel bandwidth is
programmable from less than 100 kHz to 108 MHz through a combination of analog and digital
filtering via the easy-to-use GUI software.
The EVB7 provides system designers with the ability to connect the board to any type of
baseband, FPGA or CPU and allow them to implement their ideas for various wireless
communication applications.
This document describes how to make a quick start with the LMS7002M using the EVB7
module. Section 2 begins by listing the contents of the Quick Start kit. Section 3 gives a general
description of the evaluation board features. Section 4 describes the procedure for obtaining and
installing the LMS7002M control software “Control LMS7002M” for both Windows and Linux
platforms. Section 5 describes how to connect and use the EVB and LMS7002M control
software “Control LMS7002M” for the Quick Start example configurations. Section 6 describes
in detail the EVB connectors and hardware options. Section 7 describes in detail how to use the
LMS7002M control software “Control LMS7002M”. Section Error! Reference source not
ound. describes the calibration procedure. Appendix 1 details the recommended test and
measurement equipment, and how to set up the test equipment to work with EVB7 and the
LMS7002M.

Overview of the Development Board
Figure 2 Board block diagram
A photograph of the development board is shown in Figure 1. A block diagram of the board is
shown in Figure 2. The connections are shown in blue, the LMS7002M chip is shown in green,
and the other parts are shown in orange. The core of the board is the LMS7002M transceiver
chip, which has multiple RF, analogue and digital interfaces.
The evaluation board includes RF matching networks for the LMS7002M. These matching
networks include wideband transformers to allow operation over the entire frequency range.

However, the matching networks have been optimized for operation over selected frequency
bands and offer the best performance in these bands. Connectors are provided for 4 RF
transmitter outputs and 6 RF receiver inputs. Further details of the matching networks are
provided in Section 6.3.5.
The evaluation board includes connectors for the baseband analogue differential receiver outputs
and differential transmitter inputs. Additionally, on board high speed differential to single ended
converters allow the EVB7 receivers to indirectly drive 50R test equipment such as spectrum
analysers for baseband testing.
The evaluation board includes a clock generation block, which by default, is a standalone
30.72 MHz low phase noise TXCO. TXCOs at other frequencies can also be fitted and three
different footprints are supported. The EVB7 can be easily modified to operate with external
clock sources. It can also be synchronized to the standard 10 MHz reference of measurement
equipment via an on board PLL. Details of the required changes on EVB7 are given in section
6.3.1 and 6.3.2.
EVB7 includes two kinds of digital I/O, one for control only, and two for data and control.
The USB interface is used to control the LMS7002M SPI via the LMS7002M control software.
The USB port is converted to SPI by an on board microcontroller.
The HSMC connector or the 44 pin header can be used for the buffered digital interface and can
be connected to compatible platforms such as the Lime “Stream” board. The Lime “Stream”
board also provides connections to general purpose lab equipment such as pattern generators and
logic analysers. A pin list for the digital interface can be found in Section 6.2. The logic level
for the digital interface can be set by modifying EVB7 and is described in section 6.3.4.
Additionally these connectors can be used to control the SPI but require the board modifications
described in 6.3.3.
A 7th order LC filter can be selected between the analogue output of the LMS7002M and its
digital inputs by using the LMS7002M control software. This allows additional filtering at
100 kHz (IF BW) for 2G applications.
The board includes memory to work with the LMS7002M internal microcontroller. This is
intended to provide calibration support for the LMS7002M and is currently under development.
The memory is programmed via the LMS7002M control software and the USB/SPI interface.
Test points are provided for various test signals including the LMS7002M internal peak and
RSSI detectors as well as various PLL test signals.
More detailed information on the connectors for the evaluation board can be found in Section
6.1. Information about PCB options supported is in Section 6.3.
