3 Recommended Footprint

The following figure shows the recommended compatible footprint of SIM5360 and SIM5320.

Figure 2: Footprint recommendation (Unit: mm)

4 Hardware Reference Design

The following chapters describe compatible design of SIM5360 and SIM5320 on main functionalities.

4.1 Power Supply

The power supply pins of SIM5360 include four VBAT pins (pin 62&63, pin 38&39). VBAT directly supplies the power to RF circuit and baseband circuit. All four VBAT pins of SIM5360 must be used together. The figure 4 is the reference design of SIM5360 VBAT power supply.



The power supply pins of SIM5320 include VBAT_RF and VBAT_BB. VBAT_RF directly supplies the power to RF circuit; VBAT_BB supplies the power to the baseband circuit. The following figure is the reference design of +5V input power supply. The designed output for the power supply is 4.1V; here a linear regulator can be used.

Figure 3: Reference circuit of the LDO power supply

In addition, in order to get a stable power source, it is suggested to use a zener diode of which reverse zener voltage is 5.1V and dissipation power is more than 500mW.

4.2 USB Interface

SIM5360 and SIM5320 module contains a USB interface. This interface is compliant with the USB2.0 specification. The following circuit is the reference design of USB interface. It is recommended to use an ESD protection component such as ON SEMI (www.onsemi.com ) ESD9M5.0ST5G or ESD9L5.0ST5G.

Figure 6: USB interface

4.3 Network Status Indication

The GPIO1 pin can be used to drive a network status indicator LED. The following circuit is the reference design.

4.5 USIM Interface

The USIM provides the required subscription verification information to allow the mobile equipment to attach to a GSM or UMTS network. Both 1.8V and 3.0V SIM Cards are supported.

It is recommended to use an ESD protection component such as ST (www.st.com ) ESDA6V1W5. The following circuit is a reference design for SIM5360 and SIM5320 USIM circuit.

Figure 9: USIM interface reference circuit

4.6 UART Interface

The SIM5360 UART is 1.8V interface. The SIM5320 UART is 2.6V interface. A level shifter should be used if user’s application is equipped with a 3.3V UART interface. The level shifter TXB0108RGYR provided by Texas Instruments is recommended. The reference design of the TXB0108RGYR is in the following figures.

4.7 RF Interface

SIM5360 and SIM5320 provides RF antenna interface. Customer’s antenna should be located in the host board and connected to module’s antenna pad through micro-strip line or other types of RF trace and the trace impedance must be controlled in 50Ω. The following circuit is a reference design for SIM5360 and SIM5320 RF antenna circuit.

Figure 11: Main Antenna matching circuit

SIM5360 provides RF diversity antenna interface. Customer’s antenna should be located in the host board and connected to module’s antenna pad through micro-strip line or other types of RF trace and the trace impedance must be controlled in 50Ω. The following circuit is a reference design for SIM5360 RF diversity antenna circuit.



Figure 12: DiversityAntenna matching circuit of SIM5360

In figure 11 and figure 12, the components R1/R3,C1/C3,C2/C5 and R2/R5 is used for antenna matching, the value of components can only be got after the antenna tuning, usually, they are provided by antenna vendor. By default, the R1/R3, R2/R5 are 0 ohm resistors, and the C1/C3, C2/C5 are reserved for tuning
