User's Guide SNLU099B–January 2012–Revised August 2017 LMK04100, LMK04101, LMK04102, LMK04110, LMK04111, LMK04131, and LMK04133 User’s Guide This user’s guide describes how to set up and operate the LMK041xx evaluation modules (EVMs). The LMK041xx Evaluation Board simplifies evaluation of the LMK041xxB Precision Clock Conditioner with Dual PLLs and Integrated VCO. Configuring and controlling the board is accomplished using Texas Instruments’ TICS Pro software, which can be downloaded from TI’s website: http://www.ti.com/tool/ticspro-sw.
