PCB Design Guidelines for ADNS-5700 One Chip USB LED Sensor

Application Note 5417

Introduction

The ADNS-5700 is a one chip USB LED optical mouse

sensor. The purpose of this application note is to provide

printed circuit board (PCB) design recommendations that

can guide mouse manufacturer to produce a good quality

LED mouse for optimum performance.

A good USB corded mouse design should demonstrate

good performance in all areas including:

• Passes EN 61000-4-4/IEC 801-4 Electrical Fast Transient

• Passes FCC Part 15C Class B and worldwide analogous

• Passes IEC 61000-4-2:2001Electrostatic discharge(ESD)
