1 Introduction

The TLV3602EVM is an evaluation board designed to evaluate the high-speed TLV3602 comparator. The
TLV3602EVM has layout options intended to make it simple to evaluate timing performance with different
measurement tools. The output of the TLV3602 allows for direct connection to a 50 Ω terminated oscilloscope.
