This timed-tuning ensures that the phase offsets between VCO/PLL chains will remain constant after each re-tune. See notes below: +- Phase synchronization with the UBX is only supported on the X3x0 Series +- Phase synchronization with the SBX works on both N2x0 and X3x0 Series - There is a random phase offset between any two frontends - This phase offset is different for different LO frequencies - This phase offset remains constant after retuning - - Due to a divider, UBX phase offset will be randomly +/- 180 deg after re-tune on N200/N210. - On X300/X310, phase sync with UBX fully works. - This phase offset will drift over time due to thermal and other characteristics - Periodic calibration will be necessary for phase-coherent applications diff --git a/host/docs/usrp_e3x0.dox b/host/docs/usrp_e3x0.dox index bdcfe8bfb..64e784399 100644 --- a/host/docs/usrp_e3x0.dox +++ b/host/docs/usrp_e3x0.dox @@ -86,7 +86,7 @@ You should be presented with a shell similar to the following \section e3x0_sdk Using the SDK -In order to facilitate software development for the integrated ARM Cortex-A9 processor, a <a href="http://www.yoctoproject.org">Yocto Project</a> based SDK is provided in the download section of our website. +In order to facilitate software development for the integrated ARM Cortex-A9 processor, a <a href="http://www.yoctoproject.org">Yocto Project</a> based SDK is provided in the download section of our <a href="http://files.ettus.com/e3xx_images">website</a>.
