1.1. Safety Information
The following safety precautions must be observed during all phases of operation, such as usage, service
or repair of any cellular terminal or mobile incorporating EG95 module. Manufacturers of the cellular
terminal should send the following safety information to users and operating personnel, and incorporate
these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for
customers’ failure to comply with these precautions.
Full attention must be given to driving at all times in order to reduce the risk of an
accident. Using a mobile while driving (even with a handsfree kit) causes
distraction and can lead to an accident. You must comply with laws and regulations
restricting the use of wireless devices while driving.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is
switched off. The operation of wireless appliances in an aircraft is forbidden, so as
to prevent interference with communication systems. Consult the airline staff about
the use of wireless devices on boarding the aircraft, if your device offers an
Airplane Mode which must be enabled prior to boarding an aircraft.
Switch off your wireless device when in hospitals,clinics or other health care
facilities. These requests are designed to prevent possible interference with
sensitive medical equipment.
Cellular terminals or mobiles operating over radio frequency signal and cellular
network cannot be guaranteed to connect in all conditions, for example no mobile
fee or with an invalid (U)SIM card. While you are in this condition and need
emergent help, please remember using emergency call. In order to make or
receive a call, the cellular terminal or mobile must be switched on and in a service
area with adequate cellular signal strength.
Your cellular terminal or mobile contains a transmitter and receiver. When it is ON,
it receives and transmits radio frequency energy. RF interference can occur if it is
used close to TV set, radio, computer or other electric equipment.
In locations with potentially explosive atmospheres, obey all posted signs to turn
off wireless devices such as your phone or other cellular terminals. Areas with
potentially explosive atmospheres include fuelling areas, below decks on boats,
fuel or chemical transfer or storage facilities, areas where the air contains
chemicals or particles such as grain, dust or metal powders, etc.

3.6.2. Decrease Voltage Drop
The power supply range of the module is from 3.3V to 4.3V. Please make sure that the input voltage will
never drop below 3.3V. The following figure shows the voltage drop during burst transmission in 2G
network. The voltage drop will be less in 3G and 4G networks.

Drop
Min.3.3V
Figure 7: Power Supply Limits during Burst Transmission
To decrease voltage drop, a bypass capacitor of about 100¾F with low ESR (ESR=0.7Ί) should be used,
and a multi-layer ceramic chip (MLCC) capacitor array should also be reserved due to its ultra-low ESR. It
is recommended to use three ceramic capacitors (100nF, 33pF, 10pF) for composing the MLCC array,
and place these capacitors close to VBAT_BB/VBAT_RF pins. The main power supply from an external
application has to be a single voltage source and can be expanded to two sub paths with star structure.
The width of VBAT_BB trace should be no less than 1mm, and the width of VBAT_RF trace should be no
less than 2mm. In principle, the longer the VBAT trace is, the wider it will be.
In addition, in order to get a stable power source, it is suggested that a zener diode whose dissipation
power is more than 0.5W should be used. The following figure shows the star structure of the power
supply.

3.6.3. Reference Design for Power Supply
Power design for the module is very important, as the performance of the module largely depends on the
power source. The power supply should be able to provide sufficient current up to 2A at least. If the
voltage drop between the input and output is not too high, it is suggested that an LDO should be used to
supply power for the module. If there is a big voltage difference between the input source and the desired
output (VBAT), a buck converter is preferred to be used as the power supply.
The following figure shows a reference design for +5V input power source. The typical output of the power

In order to enhance the reliability and availability of the (U)SIM cards in customers’ applications, please
follow the criteria below in the (U)SIM circuit design:






Keep placement of (U)SIM card connector to the module as close as possible. Keep the trace length
as less than 200mm as possible.
Keep (U)SIM card signals away from RF and VBAT traces.
Assure the ground between the module and the (U)SIM card connector short and wide. Keep the
trace width of ground and USIM_VDD no less than 0.5mm to maintain the same electric potential.
To avoid cross-talk between USIM_DATA and USIM_CLK, keep them away from each other and
shield them with surrounded ground.
In order to offer good ESD protection, it is recommended to add a TVS diode array whose parasitic
capacitance should not exceed 15pF. The 0Ί resistors should be added in series between the
module and the (U)SIM card so as to suppress EMI spurious transmission and enhance ESD
protection. The 33pF capacitors are used for filtering interference of EGSM900. Please note that the
(U)SIM peripheral circuit should be close to the (U)SIM card connector.
The pull-up resistor on USIM_DATA line can improve anti-jamming capability when long layout trace
and sensitive occasion are applied, and should be placed close to the (U)SIM card connector.
3.10. USB Interface
EG95 contains one integrated Universal Serial Bus (USB) interface which complies with the USB 2.0
specification and supports high-speed (480Mbps) and full-speed (12Mbps) modes. The USB interface is
used for AT command communication, data transmission, GNSS NMEA sentences output, software
debugging, firmware upgrade and voice over USB*. The following table shows the pin definition of USB

A common mode choke L1 is recommended to be added in series between the module and customer’s
MCU in order to suppress EMI spurious transmission. Meanwhile, the 0Ί resistors (R3 and R4) should be
added in series between the module and the test points so as to facilitate debugging, and the resistors are
not mounted by default. In order to ensure the integrity of USB data line signal, L1/R3/R4 components
must be placed close to the module, and also these resistors should be placed close to each other. The
extra stubs of trace must be as short as possible.
The following principles should be complied with when design the USB interface, so as to meet USB 2.0
specification.




It is important to route the USB signal traces as differential pairs with total grounding. The impedance
of USB differential trace is 90Ί.
Do not route signal traces under crystals, oscillators, magnetic devices and RF signal traces. It is
important to route the USB differential traces in inner-layer with ground shielding on not only upper
and lower layers but also right and left sides.
Pay attention to the influence of junction capacitance of ESD protection component on USB data
lines. Typically, the capacitance value should be less than 2pF.
Keep the ESD protection components to the USB connector as close as possible.

3.12. PCM and I2C Interfaces
EG95 provides one Pulse Code Modulation (PCM) digital interface for audio design, which supports the
following modes and one I2C interface:


Primary mode (short frame synchronization, works as both master and slave)
Auxiliary mode (long frame synchronization, works as master only)
In primary mode, the data is sampled on the falling edge of the PCM_CLK and transmitted on the rising
edge. The PCM_SYNC falling edge represents the MSB. In this mode, the PCM interface supports
256kHz, 512kHz, 1024kHz or 2048kHz PCM_CLK at 8kHz PCM_SYNC, and also supports 4096kHz
PCM_CLK at 16kHz PCM_SYNC.
In auxiliary mode, the data is also sampled on the falling edge of the PCM_CLK and transmitted on the
rising edge. The PCM_SYNC rising edge represents the MSB. In this mode, the PCM interface operates
with a 256kHz, 512kHz, 1024kHz or 2048kHz PCM_CLK and an 8kHz, 50% duty cycle PCM_SYNC.
EG95 supports 16-bit linear data format. The following figures show the primary mode’s timing
relationship with 8KHz PCM_SYNC and 2048KHz PCM_CLK, as well as the auxiliary mode’s timing
relationship with 8KHz PCM_SYNC and 256KHz PCM_CLK.

used to resist the fall of signals caused by high speed movement and multipath effect, and a GNSS
antenna interface which is only supported on EG95-NA. The antenna ports have an impedance of 50Ί.

3.
Keep a proper distance between the main antenna and the Rx-diversity antenna to improve the
receiving sensitivity.
ANT_DIV function is enabled by default. AT+QCFG="diversity",0 command can be used to disable
receive diversity.
Place the π-type matching components (R1/C1/C2, R2/C3/C4) as close to the antenna as possible.
5.1.4. Reference Design of RF Layout
For user’s PCB, the characteristic impedance of all RF traces should be controlled as 50Ω. The
impedance of the RF traces is usually determined by the trace width (W), the materials’ dielectric constant,
the distance between signal layer and reference ground (H), and the clearance between RF trace and
ground (S). Microstrip line or coplanar waveguide line is typically used in RF layout for characteristic
impedance control. The following are reference designs of microstrip line or coplanar waveguide line with
different PCB structures.

Figure 34: Coplanar Waveguide Line Design on a 4-layer PCB (Layer 4 as Reference Ground)
In order to ensure RF performance and reliability, the following principles should be complied with in RF
layout design:





Use impedance simulation tool to control the characteristic impedance of RF traces as 50Ί.
The GND pins adjacent to RF pins should not be designed as thermal relief pads, and should be fully
connected to ground.
The distance between the RF pins and the RF connector should be as short as possible, and all the
right angle traces should be changed to curved ones.
There should be clearance area under the signal pin of the antenna connector or solder joint.
The reference ground of RF traces should be complete. Meanwhile, adding some ground vias around
RF traces and the reference ground could help to improve RF performance. The distance between
the ground vias and RF traces should be no less than two times the width of RF signal traces (2*W).
For more details about RF layout, please refer to document [4].

In order to achieve better performance of the module, it is recommended to comply with the following
principles for thermal consideration:








On customers’ PCB design, please keep placement of the module away from heating sources,
especially high power components such as ARM processor, audio power amplifier, power supply, etc.
Do not place components on the opposite side of the PCB area where the module is mounted, in
order to facilitate adding of heatsink when necessary.
Do not apply solder mask on the opposite side of the PCB area where the module is mounted, so as
to ensure better heat dissipation performance.
The reference ground of the area where the module is mounted should be complete, and add ground
vias as many as possible for better heat dissipation.
Make sure the ground pads of the module and PCB are fully connected.
According to customers’ application demands, the heatsink can be mounted on the top of the module,
or the opposite side of the PCB area where the module is mounted, or both of them.
The heatsink should be designed with as many fins as possible to increase heat dissipation area.
Meanwhile, a thermal pad with high thermal conductivity should be used between the heatsink and
module/PCB.
The size of the heatsink should be larger than that of the module’s shielding cover to avoid the
deformation of the shielding cover.
The following shows two kinds of heatsink designs for reference and customers can choose one or both
of them according to their application structure.

NOTE
The module offers the best performance when the internal BB chip stays below 105°C. When the
maximum temperature of the BB chip reaches or exceeds 105°C, the module works normal but provides
reduced performance (such as RF output power, data rate, etc.). When the maximum BB chip
temperature reaches or exceeds 115°C, the module will disconnect from the network, and it will recover to
network connected state after the maximum temperature falls below 115°C. Therefore, the thermal design
should be maximally optimized to make sure the maximum BB chip temperature always maintains below
105°C. Customers can execute AT+QTEMP command and get the maximum BB chip temperature from
the first returned value.

Storage, Manufacturing and
Packaging
8.1. Storage
EG95 is stored in a vacuum-sealed bag. The storage restrictions are shown as below.
1. Shelf life in the vacuum-sealed bag: 12 months at <40ÂşC/90%RH.
2. After the vacuum-sealed bag is opened, devices that will be subjected to reflow soldering or other
high temperature processes must be:


Mounted within 168 hours at the factory environment of ≤30ºC/60%RH.
Stored at <10%RH.
3. Devices require baking before mounting, if any circumstance below occurs.


When the ambient temperature is 23ÂşCÂą5ÂşC and the humidity indication card shows the humidity
is >10% before opening the vacuum-sealed bag.
Device mounting cannot be finished within 168 hours at factory conditions of ≤30ºC/60%RH.
4. If baking is required, devices may be baked for 8 hours at 120ÂşCÂą5ÂşC.
NOTE
As the plastic package cannot be subjected to high temperature, it should be removed from devices
before high temperature (120ÂşC) baking. If shorter baking time is desired, please refer to
IPC/JEDECJ-STD-033 for baking procedure.

8.2. Manufacturing and Soldering
Push the squeegee to apply the solder paste on the surface of stencil, thus making the paste fill the
stencil openings and then penetrate to the PCB. The force on the squeegee should be adjusted properly
so as to produce a clean stencil surface on a single pass. To ensure the module soldering quality, the
thickness of stencil for the module is recommended to be 0.18mm. For more details, please refer to
document [3].
It is suggested that the peak reflow temperature is 235ÂşC~245ÂşC (for SnAg3.0Cu0.5 alloy). The absolute
maximum reflow temperature is 260ÂşC. To avoid damage to the module caused by repeated heating, it is
suggested that the module should be mounted after reflow soldering for the other side of PCB has been
completed. Recommended reflow soldering thermal profile is shown below:

11 Appendix C GPRS Multi-slot Classes
Twenty-nine classes of GPRS multi-slot modes are defined for MS in GPRS specification. Multi-slot
classes are product dependent, and determine the maximum achievable data rates in both the uplink and
downlink directions. Written as 3+1 or 2+2, the first number indicates the amount of downlink timeslots,
while the second number indicates the amount of uplink timeslots. The active slots determine the total
number of slots the GPRS device can use simultaneously for both uplink and downlink communications.
The description of different multi-slot classes is shown in the following table.

FCC Certification Requirements.
According to the definition of mobile and fixed device is described in Part 2.1091(b), this
device is a mobile device.
And the following conditions must be met:
1. This Modular Approval is limited to OEM installation for mobile and fixed applications
only. The antenna installation and operating configurations of this transmitter, including
any applicable source-based time- averaging duty factor, antenna gain and cable loss
must satisfy MPE categorical Exclusion Requirements of 2.1091.
2. The EUT is a mobile device; maintain at least a 20 cm separation between the EUT and
the user’s body and must not transmit simultaneously with any other antenna or
transmitter.
3.A label with the following statements must be attached to the host end product: This
device contains FCC ID: XMR2010E*1A.
4.To comply with FCC regulations limiting both maximum RF output power and human
exposure to RF radiation, maximum antenna gain (including cable loss) must not
exceed:
WCDMA/LTE: <4dBi
5. This module must not transmit simultaneously with any other antenna or
transmitter
6. The host end product must include a user manual that clearly defines operating
requirements and conditions that must be observed to ensure compliance with current
FCC RF exposure guidelines.
For portable devices, in addition to the conditions 3 through 6 described above, a
separate approval is required to satisfy the SAR requirements of FCC Part 2.1093
If the device is used for other equipment that separate approval is required for all other
operating configurations, including portable configurations with respect to 2.1093 and
different antenna configurations.
For this device, OEM integrators must be provided with labeling instructions of finished
products. Please refer to KDB784748 D01 v07, section 8. Page 6/7 last two
paragraphs:
A certified modular has the option to use a permanently affixed label, or an electronic
label. For a permanently affixed label, the module must be labelled withan FCC ID Section 2.926 (see 2.2 Certification (labelling requirements) above). The OEM manual
must provide clear instructions explaining to the OEM the labelling
requirements,options and OEM user manual instructions that are required (see next
paragraph).
For a host using a certified modular with a standard fixed label, if (1) the module’s FCC
ID is notvisible when installed in the host, or (2) if the host is marketed so that end users
do not havestraightforward commonly used methods for access to remove the module
so that the FCC ID ofthe module is visible; then an additional permanent label referring
to the enclosed module:“Contains Transmitter Module FCC ID:;05(*1$” or
“Contains FCC ID: XMR201807EG95NA” mustbe used. The host OEM user manual must
also contain clear instructions on how end users can find and/or access the module and
the FCC ID.
The final host / module combination may also need to be evaluated against the FCC
Part 15B criteria for unintentional radiators in order to be properly authorized for
operation as a Part 15 digital device.
The user’s manual or instruction manual for an intentional or unintentional radiator shall
caution the user that changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment. In
cases where the manual is provided only in a form other than paper, such as on a
computer disk or over the Internet, the information required by this section may be
included in the manual in that alternative form, provided the user can reasonably be

cause undesired operation.
Changes or modifications not expressly approved by the manufacturer could void the
user’s authority to operate the equipment.
To ensure compliance with all non-transmitter functions the host manufacturer is
responsible for ensuring compliance with the module(s) installed and fully operational. For
example, if a host was previously authorized as an unintentional radiator under the
Declaration of Conformity procedure without a transmitter certified module and a module
is added, the host manufacturer is responsible for ensuring that the after the module is
installed and operational the host continues to be compliant with the Part 15B
unintentional radiator requirements.
The host product shall be properly labelled to identify the modules within the host
product.
The Innovation, Science and Economic Development Canada certification label of a
module shall be clearly visible at all times when installed in the host product; otherwise,
