NB7NPQ1102MCMUGEVB

Introduction

The NB7NPQ1102MCMUGEVB evaluation board was

developed to provide a convenient platform to quickly

verify the operation of the NB7NPQ1102M redriver in a

USB type−C system environment.

This evaluation board manual contains:

• Information on the NB7NPQ1102M Evaluation Board

• Board Schematics

• Bill of Materials

Board Features

• Accommodates the Functional Evaluation of the

NB7NPQ1102M

• Acts as a Reference Design that Can Easily be

Modified for Active Cables, UFP (Upstream Facing

Port), DFP (Downstream Facing Port), and DRP (Dual

Role Port) Applications

• Type−C Plug and Receptacle to Easily Place in the

Existing System Environment

• On Board Control Pins for Adjusting Settings without

Compromising Form Factor

• Two NB7NPQ1102M Devices to Facilitate USB

Type−C Connections without using a Multiplexor

Part Description

The NB7NPQ1102M is a 3.3 V dual channel, high gain,

redriver for USB 3.1 Gen 1 and USB 3.1 Gen 2 applications

that supports both 5 Gbps and 10 Gbps data rates. Signal

integrity degrades from PCB traces, transmission cables,

and inter−symbol interference (ISI). The NB7NPQ1102M

compensates for these losses by engaging varying levels of

equalization at the input receiver, and flat gain amplification

on the output transmitter. The Flat Gain and Equalization are

controlled by four level control pins. Each channel has a set

of independent control pins to make signal optimization

possible.

After power up, periodic check of TX output is made for

the receiver connection. When the receiver is detected, the

RX termination becomes enabled and the device is set to

perform the redriver function. Note that both the channels

are independent of each other. The flexibility of this part

allows it to fit into many system applications

The NB7NPQ1102M comes in a small 3 x 3 mm UQFN16

package and is specified to operate across the entire

industrial temperature range of –40°C to 85°C.

This manual should be used in conjunction with the device

datasheet which contains full technical details on the device

specifications and operation.
