Page 3: General Description
CodeLoader software included can be run on a PC to facilitate the LMX2531LQ1700E internal register programming for the evaluation and measurement. In addition to this cable assembly, there is a microwire buffer board that ensures that the proper voltage levels are provided to the microwire inputs and also this reduces digital noise from computers through the parallel port. -
