LimeSDR

The LimeSDR is a low-cost SDR board featuring the Lime Microsystems LMS7002 RF chip.

Key characteristics include:
  • RF Transceiver: Lime Microsystems LMS7002M MIMO FPRF
  • FPGA: Altera Cyclone IV EP4CE40F23 – also compatible with EP4CE30F23
  • Memory: 256 MBytes DDR2 SDRAM
  • USB 3.0 controller: Cypress USB 3.0 CYUSB3014-BZXC
  • Oscillator: Rakon RPT7050A @ 30.72MHz
  • Continuous frequency range: 100 kHz – 3.8 GHz
  • Bandwidth: 61.44 MHz
  • RF connection: 10 U.FL connectors (6 RX, 4 TX)
  • Power Output (CW): up to 10 dBm
  • Multiplexing: 2×2 MIMO
  • Power: micro USB connector or optional external power supply
  • Status indicators: programmable LEDs
  • Dimensions: 100 mm x 60 mm

RF Output Power

TBD

Clock

The on-board clock is a 250ppb VCTCXO. GSM strictly requires 30ppb, but 250ppb should be sufficient for laboratory use.

Clock Calibration

TBD

Using external clock reference

OsmoTRX on LimeSDR

In terms of OsmoTRX support, you will a relatively complex driver stack consisting of:
  • LimeSuite containing the actual drivers and utilities for LimeSDR (version 17.09 or later required)
  • SoapySDR as middleware that wraps LimeSuite
  • SoapyUHD as plug-in exposing SoapySDR devices to UHD
  • UHD as the driver interface below OsmoTRX

You will need to observe the following dependencies when building the above:
  1. SoapyUHD depends on SoapySDR
  2. LimeSuite depends on SoapySDR.

Verifying the driver stack

You can ensure that LimeSuite recognizes your device using the LimeUtil part of LimeSuite:

$ LimeUtil --find
  * [LimeSDR-USB, media=USB 3.0, module=STREAM, addr=1d50:6108, serial=0009060B00xxyyzz]

You can ensure that SoapySDR and LimeSuite work together as expected using the SoapySDRUtil part of SoapySDR:

$ ./SoapySDRUtil --find

linux; GNU C++ version 6.3.0 20170221; Boost_106200; UHD_003.009.005-0-unknown

STEP BY STEP GUIDE TO INSTALL OSMO_TRX WITH LimeSDR from source (using ubuntu 16.04)

---Install LimeSuite, UHD and SoapyUHD 

sudo add-apt-repository -y ppa:myriadrf/drivers
sudo apt-get update

#install core library and build dependencies
sudo apt-get install git g++ cmake libsqlite3-dev

#install hardware support dependencies
sudo apt-get install libsoapysdr-dev libi2c-dev libusb-1.0-0-dev

#install graphics dependencies
sudo apt-get install libwxgtk3.0-dev freeglut3-dev

---Install LimeSuite

git clone https://github.com/myriadrf/LimeSuite.git
cd LimeSuite
mkdir builddir && cd builddir
cmake ../
make -j4
sudo make install
sudo ldconfig

cd LimeSuite/udev-rules
sudo ./install.sh

Type “LimeSuiteGUI” on terminal to check GUI is running
