DESIGN CONSIDERATIONS

Chapter 2 – Design Considerations

USB Design

MultiTech recommends that you review Intel's High Speed USB Platform Design Guidelines for information about
USB signal routing, impedance, and layer stacking. Also:

Shield USB cables with twisted pairs (especially those containing D+/D-).

Use a single 5V power supply for USB devices. See Power Draw for current (ampere) requirements.

Route D+/D- together in parallel with the trace spacing needed to achieve 90 ohms differential impedance
for the USB pair and to maintain a 20 mil space from the USB pair and all other signals.

If power is provided externally, use a common ground between the carrier board and the device.

Your device may not power up on all Host PCs or host USB devices due to the higher current requirements
of the cellular radio. Check your particular USB host port or PC motherboard's electrical specs for details on
max current capabilities of the particular USB port you are trying to use.

Depending on your design, you may be able to use a dual USB cable to share the current between two low
power USB ports or create a custom USB cable that provides external power.

Noise Suppression Design

Adhere to engineering noise-suppression practices when designing a printed circuit board (PCB). Noise suppression
is essential to the proper operation and performance of the modem and surrounding equipment.

Any OEM board design must consider both on-board and off-board generated noise that can affect digital signal
processing. Both on-board and off-board generated noise that is coupled on-board can affect interface signal levels
and quality. Noise in frequency ranges that affect modem performance is of particular concern.

On-board generated electromagnetic interference (EMI) noise that can be radiated or conducted off-board is
equally important. This type of noise can affect the operation of surrounding equipment. Most local government
agencies have certification requirements that must be met for use in specific environments.

Proper PC board layout (component placement, signal routing, trace thickness and geometry, and so on)
component selection (composition, value, and tolerance), interface connections, and shielding are required for the
board design to achieve desired modem performance and to attain EMI certification.

Other aspects of proper noise-suppression engineering practices are beyond the scope of this guide. Consult noise
suppression techniques described in technical publications and journals, electronics and electrical engineering text
books, and component supplier application notes.

Electromagnetic Interference

The following guidelines are offered specifically to help minimize EMI generation. Some of these guidelines are the
same as, or similar to, the general guidelines. To minimize the contribution of device-based design to EMI, you
must understand the major sources of EMI and how to reduce them to acceptable levels.

Keep traces carrying high frequency signals as short as possible.

Provide a good ground plane or grid. In some cases, a multilayer board may be required with full layers for
ground and power distribution.

Decouple power from ground with decoupling capacitors as close to the device's power pins as possible.

6 QuickCarrier™ USB-E MT100UCC-EV3 Developer Guide

DESIGN CONSIDERATIONS

Eliminate ground loops, which are unexpected current return paths to the power source and ground.

Decouple the telephone line cables at the telephone line jacks. Typically, use a combination of series
inductors, common mode chokes, and shunt capacitors. Methods to decouple telephone lines are similar to
decoupling power lines; however, telephone line decoupling may be more difficult and deserves additional
attention. A commonly used design aid is to place footprints for these components and populate as
necessary during performance/EMI testing and certification.

Decouple the power cord at the power cord interface with decoupling capacitors. Methods to decouple
power lines are similar to decoupling telephone lines.

Locate high frequency circuits in a separate area to minimize capacitive coupling to other circuits.

Locate cables and connectors to avoid coupling from high frequency circuits.

Lay out the highest frequency signal traces next to the ground grid.

If using a multilayer board design, make no cuts in the ground or power planes and be sure the ground
plane covers all traces.

Minimize the number of through-hole connections on traces carrying high frequency signals.

Avoid right angle turns on high frequency traces. Forty-five degree corners are good; however, radius turns
are better.

On 2-layer boards with no ground grid, provide a shadow ground trace on the opposite side of the board to
traces carrying high frequency signals. This will be effective as a high frequency ground return if it is three
times the width of the signal traces.

Distribute high frequency signals continuously on a single trace rather than several traces radiating from
one point.

Electrostatic Discharge Control

Handle all electronic devices with precautions to avoid damage due to the static charge accumulation.

See the ANSI/ESD Association Standard (ANSI/ESD S20.20-1999) – a document “for the Development of an
Electrostatic Discharge Control for Protection of Electrical and Electronic Parts, Assemblies and Equipment.” This
document covers ESD Control Program Administrative Requirements, ESD Training, ESD Control Program Plan
Technical Requirements (grounding/bonding systems, personnel grooming, protected areas, packaging, marking,
equipment, and handling), and Sensitivity Testing.

MultiTech strives to follow these recommendations. Input protection circuitry is incorporated in MultiTech devices
to minimize the effect of static buildup. Take precautions to avoid exposure to electrostatic discharge during
handling.

MultiTech uses and recommends that others use anti-static boxes that create a faraday cage (packaging designed
to exclude electromagnetic fields). MultiTech recommends that you use our packaging when returning a product
and when you ship your products to your customers.

CELLULAR INFORMATION

Chapter 3 – Cellular Information

Antenna System Cellular Devices

The cellular/wireless performance depends on the implementation and antenna design. The integration of the
antenna system into the product is a critical part of the design process; therefore, it is essential to consider it early
so the performance is not compromised. If changes are made to the device's certified antenna system, then
recertification will be required by specific network carriers.
