Temperature Range
–20°C ~ +55°C This range is defined by 3GPP (the global
standard for wireless mobile communication). Telit guarantees its modules to comply with all the 3GPP requirements and to have full functionality of the module with in this range.
–40°C ~ +85°C Telit guarantees full functionality within this
range as well. However, there may possibly be some performance deviations in this extended range relative to 3GPP requirements, which means that some RF parameters may deviate from the 3GPP specification in the order of a few dB. For example: receiver sensitivity or maximum output power may be slightly degraded.
Even so, all the functionalities, such as call connection, SMS, USB communication, UART activation etc., will be maintained, and the effect of such degradations will not lead to malfunction.

** Loop-back mode in call equipment
*** 3.3 voltage / room temperature
Information – The electrical design for the power supply must ensure a peak current output of at least 2A.
General Design Rules
The principal guidelines for the Power Supply Design embrace three different design steps:
Electrical design
Thermal design
PCB layout
4.3.1. Electrical Design Guidelines
The electrical design of the power supply depends strongly on the power source where this power is drained.
4.3.1.1. + 5V Input Source Power Supply – Design Guidelines
The desired output for the power supply is 3.3V. So, the difference between the
input source and the desired output is not big, and therefore a linear regulator can be used. A switching power supply is preferred to reduce power consumption.
When using a linear regulator, a proper heat sink must be provided to dissipate the
power generated.
A bypass low ESR capacitor of adequate capacity must be provided to cut the
current absorption peaks close to the LM960 module. A 100 F tantalum capacitor is usually suitable on VBATT.
Make sure that the low ESR capacitor on the power supply output (usually a
tantalum one) is rated at least 10V.
A protection diode must be inserted close to the power input to protect the LM960
module from power polarity inversion.
1VV0301485 Rev. 3 Page 29 of 74 2018-12-14
LM960 HW Design Guide
4.3.2. Thermal Design Guidelines
The thermal design for the power supply heat sink must be done with the following specifications:
Average current consumption during RF transmission @PWR level max in LM960
as shown in Section 4.2, Power Consumption table.
Information – The average consumption during transmission depends on the power level at which the device is requested to transmit via the network.
Therefore, the average current consumption varies significantly.
Information – The thermal design for the power supply must be made keeping an average consumption at the maximum transmitting level during calls of LTE/HSPA.
Considering the very low current during Idle, especially if the Power Saving function is enabled, it is possible to consider from the thermal point of view that the device absorbs significant current only during Data session.
In LTE/WCDMA/HSPA mode, the LM960 emits RF signals continuously during transmission. Therefore, you must pay special attention how to dissipate the heat generated.
While designing the application board, the designer must make sure that the LM960 module is located on a large ground area of the application board for effective heat dissipation.
Information – The LM960 must be connected to the ground and metal chassis of the host board for best RF performance and thermal dispersion as well as to have module fixed.
The two holes at the top of the module and the main ground

The shield cover of the module and the main board of the host
board or the metal chassis of the host device should be connected with conductive materials.

LM960 HW Design Guide
4.3.3. Power Supply PCB layout Guidelines
As seen in the electrical design guidelines, the power supply must have a low ESR capacitor on the output to cut the current peaks and a protection diode on the input to protect the supply from spikes and polarity inversion. The placement of these components is crucial for the correct operation of the circuitry. A misplaced component can be useless or can even decrease the power supply performances.
The bypass low ESR capacitor must be placed close to the LM960 power input
pins, or if the power supply is of a switching type, it can be placed close to the inductor to cut the ripple, as long as the PCB trace from the capacitor to LM960 is wide enough to ensure a drop-less connection even during the 2A current peaks.
The protection diode must be placed close to the input connector where the power
source is drained.
The PCB traces from the input connector to the power regulator IC must be wide
enough to ensure that no voltage drops occur during the 2A current peaks.
The PCB traces to LM960 and the bypass capacitor must be wide enough to
ensure that no significant voltage drops occur when the 2A current peaks are absorbed. This is needed for the same above-mentioned reasons. Try to keep these traces as short as possible.
The PCB traces connecting the switching output to the inductor and the switching
diode must be kept as short as possible by placing the inductor and the diode very close to the power switching IC (only for the switching power supply). This is done to reduce the radiated field (noise) at the switching frequency (usually 100­500 kHz).
Use a good common ground plane.
Place the power supply on the board in a way to guarantee that the high current
return paths in the ground plane do not overlap any noise sensitive circuitry, such as the microphone amplifier/buffer or earphone amplifier.
The power supply input cables must be kept separate from noise sensitive lines,
such as microphone/earphone cables.
RTC
The RTC within the LM960 module does not have a dedicated RTC supply pin. The RTC block is supplied by the VBATT supply.
If VBATT power is removed, RTC is not maintained so if maintaining an internal RTC is needed, VBATT must be supplied continuously.
Reference Voltage
1.8V regulated power supply output is provided as the reference voltage to a host board. This output is active when the module is ON and goes OFF when the module is shut down.
This table lists the VREG_L6_1P8 signal of LM960.

Power On
The LM960 is automatically turning on when the VBATT is supplied.
Information – To turn on the LM960 module, the SYSTEM_RESET_N pin must not be asserted low.
6.2.1. Initialization and Activation State
After turning on the LM960 module, the LM960 is not yet activated because the SW initialization process of the LM960 module is still in process internally. It takes some time to fully complete the HW and SW initialization of the module.
For this reason, it is impossible to access LM960 during the Initialization state.
As shown in below figure, the LM960 becomes operational (in the Activation state) at least 30 seconds after the VBATT is supplied.
LM960 Initialization and Activation
Information – To check if the LM960 has completely powered on, LM960 and the host must be connected via USB. When USB driver completely loaded, the module has completely powered on and is ready to accept AT commands.
Information – Active low signals are labeled with a name that ends with “_N”
1VV0301485 Rev. 3 Page 36 of 74 2018-12-14
LM960 HW Design Guide
Information – To avoid a back-powering effect, it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the module when it is powered OFF or during an ON/OFF transition.
Power Off
To turn off the LM960, SYSTEM_RESET_N pad must be asserted low more than 1 seconds and then it should be kept low.
When the SYSTEM_RESET_N is asserted low more than 1 seconds, LM960 goes into the finalization state and after the end of the finalization process VREG_L6_1P8 will go to low.
Usually, it takes LM960 less than 200 milliseconds from asserting SYSTEM_RESET_N until reaching a complete shutdown. The DTE should monitor the status of VREG_L6_1P8 to observe the actual power-off.
Information – To completely shut down the LM960 module, the SYSTEM_RESET_N pin must be asserted and kept low.
Otherwise, the LM960 will turn on again after shut down.
Information – To avoid a back-powering effect, it is recommended to avoid having any HIGH logic level signal applied to the digital pins of the module when it is powered OFF or during an ON/OFF transition.
Warning – Not following the recommended shut-down procedures might damage the device and consequently void the warranty.

6.4.2. Unconditional Hardware Reset
To unconditionally restart the LM960 module, the SYSTEM_RESET_N pin must be asserted low more than 1 seconds and then released.
Unconditional Hardware Reset by SYSTEM_RESET_N Pad
Information – The Unconditional Hardware Reset must be used only as an emergency exit procedure, and not as a normal power-off operation.
Information – Do not use any pull-up resistor on the RESET_N line or any totem pole digital output. Using a pull-up resistor may cause latch­up problems on the LM960 power regulator and improper functioning of the module. The RESET_N line must be connected only in an open­collector configuration.

The LM960 module includes super-speed USB3.0 with high-speed USB2.0 backward compatibility. It is compliant with Universal Serial Bus Specification, Revision 3.0 and can be used for control and data transfers as well as for diagnostic monitoring and firmware update.
The USB port is typically the main interface between the LM960 module and OEM hardware.
USB 3.0 needs series capacitors on the TX lines in both directions for AC coupling. In order to interface USB3.0 with an application board of customer, 0.1uF capacitors should be installed on USB_SS_RX_P/M lines of the LM960. There are already series capacitors on USB_SS_TX_P/M lines inside LM960 module.
The USB interface suggested connection is the following:
Connection for USB Interface
Information – The USB signal traces must be routed carefully. Minimize trace lengths, number of vias, and capacitive loading. The impedance value should be as close as possible to 90 Ohms differential.

Antenna requirements
The antenna connection is one of the most important aspect in the full product design as it strongly affects the product overall performance. Hence read carefully and follow the requirements and the guidelines for a proper design.
The LM960 is provided with five RF connectors.
The available connectors are:
Primary RF antenna #0: Tx and Rx path for low bands and middle bands / 4x4
MIMO path of band41.
Primary RF antenna #0: Tx and Rx path for high bands, ultra high bands and
band32 / 4x4 MIMO path of band2(band25) and band4(band66)
Secondary RF antenna #0: Secondary RF antenna #0: Rx Diversity path for low
bands, middle bands / 4x4 MIMO path of band41 / GNSS path
Secondary RF antenna #1: Secondary RF antenna #1: Rx Diversity path for high
bands, ultra high bands and band32 / 4x4 MIMO path of band2(band25) and band4(band66)

The second Rx antenna should not be located in the close vicinity of main antenna. In order to improve Diversity Gain, Isolation and reduce mutual interaction, the two antennas should be located at the maximum reciprocal distance possible, taking into consideration the available space into the application. For the same reason, the Rx antenna should also be cross-polarized with respect to the main antenna. Isolation between main antenna and Rx antenna must be at least 10 dB in all uplink frequency bands.
Envelope Correlation Coefficient (ECC) value should be as close as possible to zero, for best diversity performance. ECC values below 0.5 on all frequency bands are recommended.

10. APPLICATION GUIDE
Debug of the LM960 Module in Production
To test and debug the mounting of the LM960 module, we strongly recommend to add several test pins on the host PCB for the following purposes:
Checking the connection between the LM960 itself and the application
Testing the performance of the module by connecting it with an external computer
Depending on the customer application, these test pins include, but are not limited to the following signals:
SYSTEM_RESET_N, W_DISABLE_N, PCIE_WAKE_N
VBATT, GND
VREG_L6_1P8
USB_D-, USB_D+
USB_SS_TX_M, USB_SS_TX_P, USB_SS_RX_M, USB_SS_RX_P
PCIE_TX_M, PCIE_TX_P, PCIE_RX_M, PCIE_RX_P
In addition, the following signals are also recommended (but not mandatory):
WAN_LED_N
GPIO_01, GPIO_02, GPIO_03, GPIO_04
Bypass Capacitor on Power Supplies
When a sudden voltage step is asserted to or a cut from the power supplies, the steep transition causes some reactions such as overshoot and undershoot. This abrupt voltage transition can affect the device causing it to not operate or to malfunction.
Bypass capacitors are needed to alleviate this behavior. The behavior can appear differently depending on the various applications. Customers must pay special attention to this issue when they design their application board.
The length and width of the power lines must be considered carefully, and the capacitance of the capacitors must be selected accordingly.
The capacitor will also prevent ripple of the power supplies and the switching noise caused in TDMA systems such as GSM.
Especially, a suitable bypass capacitor must be mounted on the following lines on the application board:
VBATT
Recommended values are:
100uF for VBATT
Customers must still consider that the capacitance mainly depends on the conditions of their application board.
Generally, more capacitance is required when the power line is longer. And if customers use the fast power down function, then more bypass capacitors should be mounted on the application board.
