{{>toc}} h1. LimeSDR The LimeSDR is a low-cost SDR board featuring the Lime Microsystems LMS7002 RF chip. h2. RF Output Power TBD h2. Clock The on-board clock is a 250ppb VCTCXO. GSM strictly requires 30ppb, but 250ppb _should_ be sufficient for laboratory use. h3. Clock Calibration TBD h3. Using external clock reference TBD h2. OsmoTRX on LimeSDR In terms of OsmoTRX support, you will a relatively complex driver stack consisting of: * "LimeSuite":https://github.com/myriadrf/LimeSuite.git containing the actual drivers and utilities for LimeSDR * "SoapySDR":https://github.com/pothosware/SoapySDR.git as middleware that wraps LimeSuite * "SoapyUHD":https://github.com/pothosware/SoapyUHD.git 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: # SoapyUHD depends on SoapySDR # LimeSuite depends on SoapySDR. h3. Verifying the driver stack You can ensure that LimeSuite recognizes your device using the *LimeUtil* part of LimeSuite: <pre> $ LimeUtil --find 109/0/0 * [LimeSDR-USB, media=USB 3.0, module=STREAM, addr=1d50:6108, serial=0009060B00xxyyzz] </pre> You can ensure that SoapySDR and LimeSuite work together as expected using the *SoapySDRUtil* part of SoapySDR: <pre> $ ./SoapySDRUtil --find 101/0/0 ###################################################### ## Soapy SDR -- the SDR abstraction library ###################################################### linux; GNU C++ version 6.3.0 20170221; Boost_106200; UHD_003.009.005-0-unknown Found device 0 addr = 1d50:6108 driver = lime label = LimeSDR-USB [USB 3.0] 9060B00462B1C media = USB 3.0 module = STREAM name = LimeSDR-USB serial = 0009060B00xxyyzz </pre>
