This chapter provides the power supply requirements, general design rules. Users can design the power supply of module to achieve

stable and well working performance according to this document.

ESIGN

ULES

When the module is used for different external applications, pay special attention to the design for the power supply.

In the process of peripheral circuit designing, users of this Module product should ensure that the external power supply circuit is

capable of providing sufficient power supply capacity firstly, and control the supply range between

3.0~4.0V(Typ.3.3V/3.8V)

strictly. If

the value above module voltage range, it will lead the main chip burned, while below required voltage range, it will affect the RF

circuit’s performance or cause shutdown and restart occurred. For the design of high-speed USB signal lines, it requires to control the

differential impedance at 90ohm. The voltage design of external circuit interfaces should match that of the module PINs, and the

detailed value can be got in Chapter 4. The module product has a good RF indicator; customers can refer to Chapter 6 in the process

of antenna circuit designing.

EQUIREMENT

The power supply of PCIE Type module is usually recommended to be within the range of

3.0~4.0V(Typ.3.3V/3.8V)

. According to the

requirement of mobile terminal device, the power supply voltage of module is 3.3V under normal working condition.

If the network is in poor situation, the antenna will transmit at the maximum power, and the transient maximum peak current can

reach as high as 2.3A. So the power supply capacity for peak current on the main board needs to be above 2.3A to satisfy the

requirement of module peak current; and the average current on the system side needs to be above 2.0A. Meanwhile, consider the

voltage drop of power supply on the side of main board. If the network is in a poor situation or under 2G, the module peak current

will be great. Therefore the power supply has to be designed in order to withstand with these current peaks without big voltage

drops; this means that both the electrical design and the board layout must be designed for this current flow. If the layout of the PCB

is not well designed a strong noise floor is generated on the ground and the supply; and exceptions such as restart of the module

may occur.

The peak current of module under the GSM BURST mode is different due to the differences in actual network environments. And its

transient current under different powers will be various as well. The greater the power is, the greater the transient current is. The

network quality also directly affects the work current of the module. If the network is in well situation, the peak work current on the

module will be small. But if the network is in poor situation, its peak current will be great as shown in Figure 5-1 (when the module

works under the EDGE/GPRS Time Slot (2-high 6-low) and CLASS10). If the module works under the 2-high work Time Slot, it requires

greater current, and the voltage drop will occur accordingly.
