3 Interface Application
3.1 Power Supply
On VBAT pads, a ripple current up to 2A typically, may cause voltage drop. Therefore, the power
supply for these pads must be able to provide sufficient current up to more than 2A in order to
avoid the voltage drop of more than 300mV.

3.1.1 Power supply Design Guide
Make sure that the voltage on the VBAT pins will never drop below 3.4V.
Note: If the power supply for BAT pins can support up to 2A, using a total of more than 220uF
capacitors is recommended, or else users must use a total of 1000uF capacitors, in order to avoid
the voltage drop of more than 300mV.
Some multi-layer ceramic chip (MLCC) capacitors (0.1/1uF) with low ESR in high frequency band
can be used for EMC.
These capacitors should be put as close as possible to VBAT pads. Also, user should keep VBAT
trace on the circuit board wider than 2 mm to minimize PCB trace impedance. The following figure
shows the recommended circuit.

In addition, in order to guard over voltage protection, it is suggested to use a zener diode with 5.1V
reverse zener voltage and more than 500mW power dissipation.

4 Crownpo CDZ55C5V1SM 500mW 0805
3.1.2 Recommended Power Supply Circuit
It is recommended that a switching modepower supply or linear regulator power supply is used. It
is important to make sure that all the components used in the power supply circuit can resist a peak
current up to 2A.
The following figure shows the linear regulatorreference circuit with 5V input and 3.8V output.
Figure 6: Linear regulator reference circuit
If there is a big voltage difference between input and output for VBAT power supply, orthe
efficiency is extremely important,then a switching mode power supply will be preferable. The
following figure shows theswitching mode power supply reference circuit.
It is recommended to use an ESD protection component such as ESDA6V1W5 produced by ST
(www.st.com
) or SMF15C produced by ON SEMI (www.onsemi.com ). Note that the USIM
peripheral circuit should be close to the USIM card socket.The following figure shows the 6-pin
SIM card holder reference circuit.
Figure 18: USIM interface reference circuit
Note: USIM_DATA has been pulled up with a100KΩ resistor to USIM_VDD in module. A 100nF
capacitor on USIM_VDD is used to reduceinterference. For more details of AT commands about
USIM, please refer to document [1].
3.5.2 SIM Card Design Guide
SIM card signal could be interferenced by some high frequency signal, it is strongly recommended
to follow these guidelines while designing:
SIM card holder should be far away from antenna
SIM traces should keep away from RF lines, VBAT and high-speed signal lines
SIM7600A-H_User Manual_V1.00 2017-11-24
29
Smart Machine Smart Decision
The traces should be as short as possible
Keep SIM card holder’s GND connect to main ground directly
Shielding the SIM card signal by ground well
Recommended to place a 100nF capacitor on SIM_VDD line and keep close to the SIM
card holder
Add some TVS which parasitic capacitance should not exceed 50pF
Add 51Ω resistor to (SIM_RST/SIM_CLK/SIM_DATA) signal could enhance ESD
protection
Add 22pF capacitor to (SIM_RST/SIM_CLK/SIM_DATA) signal to induce RF signal
interference

Recommended USIM Card Holder
It is recommended to use the 6-pin USIM socket such as C707 10M006 512 produced by

Frequency Loss
700MHz-960MHz <0.5dB
1710MHz-2170MHz <0.9dB
2300MHz-2650MHz <1.2dB
To facilitate the antenna tuning and certification test, a RF connector and an antenna matching
circuit should be added. The following figure is the recommended circuit.

Note: If the antenna is active type, the power should be given by main board, because there is no
power supply on GPS antenna pad. If the antenna is passive, it is suggested that the external
LNA should be used.
4.3.2 GNSS Application Guide
Users can adopt an active antenna or a passive antenna as GNSS signal transceiver. In this
document, all GNSS specification mentioned is from passive antenna. The following is the
reference circuit.
Figure 30: Active antenna circuit
Figure 31: Passive antenna circuit (Default)
In above figures, the components C1 and L1, L2 are used for antenna matching, the values of the
components can only be obtained after the antenna tuning and usually provided by antenna vendor.
C2 in Figure 29 is used for DC blocking. L3 is the matching component of the external LNA, and
the value of L3 is determined by the LNA characteristic and PCB layout. Both VDD of active
antenna and V_LNA need external power supplies which should be considered according to active
antenna and LNA characteristic. LDO/DCDC is recommended to get lower current consuming by
shutting down active antennas and LNA when GNSS is not working.

GNSS can be used by NMEA port. User can select NMEA as output through UART or USB.
NMEA sentences are automatic and no command is provided. NMEA sentences include GSV, GGA,
RMC, GSA, and VTG. Before using GNSS, user should configure SIM7600A-H in proper
operating mode by AT command. Please refer to related document for details. SIM7600A-H can
also get position location information through AT directly.
Note: GNSS is closed by default, it could be started by AT+CGPS. The AT command has two
parameters, the first is on/off, and the second is GNSS mode. Default mode is standalone mode.
AGPS mode needs more support from the mobile telecommunication network. Please refer to
document [24] for more details.

E. Safety Caution
Table 42: Safety caution
Marks Requirements
When in a hospital or other health care facility, observe the restrictions about the use
of mobiles. Switch the cellular terminal or mobile off, medical equipment may be
sensitive and not operate normally due to RF energy interference.
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 to
prevent interference with communication systems. Forgeting to think much of these
instructions may impact the flight safety or offend local legal action, or both.
Do not operate the cellular terminal or mobile in the presence of flammable gases or
fumes. Switch off the cellular terminal when you are near petrol stations, fuel depots,
chemical plants or where blasting operations are in progress. Operation of any
electrical equipment in potentially explosive atmospheres can constitute a safety
hazard.
Your cellular terminal or mobile receives and transmits radio frequency energy while
switched on. RF interference can occur if it is used close to TV sets, radios,
computers or other electric equipment.
Road safety comes first! Do not use a hand-held cellular terminal or mobile when
driving a vehicle, unless it is securely mounted in a holder for hands free operation.
Before making a call with a hand-held terminal or mobile, park the vehicle.
GSM cellular terminals or mobiles operate over radio frequency signals and cellular
networks and cannot be guaranteed to connect in all conditions, especially with a
mobile fee or an invalid SIM card. While you are in this condition and need emergent
help, please remember to use emergency calls. In order to make or receive calls, the
cellular terminal or mobile must be switched on and in a service area with adequate
cellular signal strength.
Some networks do not allow for emergency call if certain network services or phone
features are in use (e.g. lock functions, fixed dialing etc.). You may have to
deactivate those features before you can make an emergency call.
Also, some networks require that a valid SIM card be properly inserted in the cellular
