    ME910C1 mPCIe HW Design Guide 4. POWER SUPPLY The power supply circuitry and board layout are a very important part in the full product design and strongly reflect on the product overall performances, so please read carefully the requirements and guidelines that will follow for a proper design. Power Supply Requirements The external power supply must be connected to 3V3_AUX signal and must fulfil the following requirements:...

  • Page 16: General Design Rules

    ME910C1 mPCIe HW Design Guide General Design Rules The principal guidelines for the Power Supply Design embrace three different design steps: • The electrical design • The thermal design • The PCB layout. 4.3.1. Electrical Design Guidelines The electrical design of the power supply depends strongly from the power source where this power is drained.
  • Page 17 ME910C1 mPCIe HW Design Guide Figure 1: Linear regulator with 5V input and 3.3V output +12V Source Power Supply Design Guidelines • The desired output for the power supply is 3.3V. Due to the large difference between the input and output voltage values together with the current sinked, the linear regulator in the example above is capable but not efficient at high current sink and should not be used.

  • Page 18: Thermal Design Guidelines

    RF signals continuously during transmission. Therefore, special attention must be paid to how to dissipate the heat generated. The ME910X1 mPCIe card is designed to distribute the heat from the module IC’s to the entire PCB increasing as much as possible the heat dissipation.

  • Page 19: Power Supply Pcb Layout Guidelines

    4.3.3. Power Supply PCB Layout Guidelines Some ME910X1 versions have GSM capabilities. The GSM system is designed in such a way that the RF transmission is not continuous, otherwise it is packed into bursts at a base frequency of about 216 Hz, and the related current peaks can be as high as about 2.4A.
  • Page 20 ME910C1 mPCIe HW Design Guide • Any PCB power traces to the ME910X1-mPCIE and the Bypass capacitors must be wide enough to ensure no significant voltage drops occurs. This is for the same reason as previous point. Try to keep this trace as short as possible.

  • Page 23: Power On

    Table 13 Operating Range SIM Card Pads Power On The ME910X1-mPCIe will automatically Power ON as soon as VBATT applies to the module and W_DISABLE_N and PERST_N are HI. The module is ready for use after HW power Up and SW initialization process completes. For this reason, it is impossible to access ME910X1-PCIe during the initialization state.

  • Page 25: Unconditional Restart

    Figure 6: MODEM START AT COMMAND” procedure Unconditional Restart To unconditionally restart the ME910X1-mPCIe, the signals PERST_N and W_DISABLE_N must be tied low for at least 200 milliseconds and then released. The unconditional hardware restart must always be implemented on the application board as the software must be able to use it as an emergency exit procedure.
  • Page 26 ME910C1 mPCIe HW Design Guide W_DISABLE_N and PERST_N are in open drain configuration. PERST_N needs an external pull up resistor to 3V3_AUX.
