LMK00101 User’s Guide

This user guide describes how to set up and operate the LMK00101 evaluation board kit (EVK). The
LMK00101 is a high performance, low noise, low voltage CMOS fanout buffer. The core voltage can be
2.5 or 3.3 volts, while the power supply for the outputs can be selected from: 1.5 V, 1.8 V, 2.5 V, or 3.3 V,
provided that it does not exceed the core supply voltage .
