INTRODUCTION

The USB334x provides the physical layer interface (PHY) 2.0. Proper design tech-in systems using Hi-Speed USB

niques must be used in the printed circuit board (PCB) layout to maintain the signal integrity required for 480 Mbps oper-

ation. The USB334x is available in both 24-pin and 32-pin QFN packages; layout guidelines for general QFN packages

are provided in this application note.

Audience

This document is written for a reader that is familiar with hardware design and the USB 2.0 specification. The goal of

this application note is to provide guidance on sensitive areas of the PCB layout.

Overview

The following recommendations are for a four layer PCB layout with a Microchip part. Our recommendations are not the

only way to layout our 24-pin and 32-pin QFN packages. PCB design engineers will have his/her own preference, and

the implementation will be dependent on complexity and density of layout, PCB real estate, number and types of devices

in circuit and the environment that the final product will reside in. For example, the PCB described in this application

note has components on both sides of the board. A four layer board could be realized with components on one side only.
