Documentation for the Lime Microsystems Field Programmable RF (FPRF) Transceiver IC
Originally logged by @chemeris : LOOPBBEN register is not specified entirely in the documentation. Check the "LMS6002D IF-RF LoopBack Options.pdf" for a diagram of its connections and the values below...
Originally logged by @chemeris : Envelope detector is in fact peak detector of peak detector, it shows IQ imbalance (phase/gain error). Unfortunately, its dynamic range limits its use as a...
Originally logged by @chemeris : Peak detector measures signal level at the TX output. The idea was to use it for TX LO leakage calibration but its dynamic range is...
Originally logged by @chemeris : RXTIA is a synonym for RXVGA1. TIA stands for Trans Impedance Amplifier. That was the initial block name but changed later to RX VGA1 for...
Originally logged by @chemeris : SRXEN/STXEN registers are equivalent to TXEN/RXEN pins. Internal control signals are constructed using logical AND in the following way: iTXEN = TXEN and STXEN iRXEN...
Originally logged by @chemeris: "4.1 General DC Calibration Procedure" procedure is incomplete and often shows failure when it actually completes fine. Refer to FAQ, question 4.7 for a workaround.
Originally logged by @chemeris: "Figure 3.8: RX FE control" misses an important configuration register "SELOUT[1:0]: Select output buffer in RX PLL". This configuration register must be used together with LNASEL_RXFE...
Originally logged by @chemeris: The purpose of the "LO Leakage" label at the "Figure 1: Functional block diagram" is not to show the path of LO leakage. :) Actually it...
