3.3 Power Sources and Grounds
The PCI Express Mini Card provides two power sources: one is 3.3 Vaux (+3.3 Vaux)
and the other is 1.5 V (+1.5 V). For the PCIe Adapter, however, +3.3 Vaux is the only
voltage supply that is available. The input voltage is 3.3 V±9%, as specified by PCI
Express Mini CEM Specifications 1.2.
Table 3-2 Power and ground specifications
Name Pins Minimum Typical Maximum
VCC_3V3 2, 24, 39, 41and 52 3.0 V 3.3 V 3.6 V
GND 4, 9, 15, 18, 21, 26, 27, 29,
34, 35, 37, 40, 43, and 50 0 V
To minimize the RF radiation through the power lines, it is suggested to add ceramic capacitors
of 10 pF and 100 nF in the ground beside the Mini PCI Express connector on the host side.
3.4 Power Supply Time Sequence
Figure 3-2 shows the MU609 with 3.3 V voltage and USB D+ power supply time
sequence.

3.5 WAKE# Signal
WAKE# pin (signal that the module uses to activate the PC) supports software control.
This signal is used for 3G module to wake up the host. It is designed as a OC gate, so
it should be pulled up by the host and it is active-low.

3.6 W_DISABLE# Signal
The W_DISABLE# signal is provided to allow users to disable wireless
communications add-in cards.
The MU609 module does not support this function now.
3.7 LED_WWAN# Signal
MU609 provides a LED_WWAN# signal to indicate the RF status. This function is
under development.

3.8 USB Interface
The MU609 module is compliant with USB 2.0 protocol. The USB interface is powered
directly from the VBAT supply. The USB input/output lines are compatible with the
USB 2.0 signal specifications. Figure 3-5 shows the circuit of the USB interface.

3.9.2 Circuit Recommended for the USIM Card Interface
As the Mini PCIe Adapter is not equipped with an USIM socket, you need to place an
USIM socket on the user interface board.
Figure 3-6 shows the circuit of the USIM card interface.

To meet the requirements of 3GPP TS 51.010-1 protocols and electromagnetic
compatibility (EMC) authentication, the USIM socket should be placed near the
PCIe interface (it is recommended that the PCB circuit connects the PCIe interface
and the USIM socket does not exceed 100 mm), because a long circuit may lead to
wave distortion, thus affecting signal quality.
It is recommended that you wrap the area adjacent to the UIM_CLK and
UIM_DATA signal wires with ground. The Ground pin of the USIM socket and the
Ground pin of the USIM card must be well connected to the power Ground pin
supplying power to the PCIe Adapter.
A 100 nF capacitor and1 μF capacitor are placed between the UIM_PWR and GND
pins in a parallel manner (If UIM_PWR circuit is too long, that the larger
capacitance such as 4.7 μF can be employed if necessary). Three 33 pF
capacitors are placed between the UIM_DATA and Ground pins, the UIM_RESET
and Ground pins, and the UIM_CLK and Ground pins in parallel to filter
interference from RF signals.
It is recommended to take electrostatic discharge (ESD) protection measures near
the USIM card socket. The TVS diode with Vrwm of 5 V and junction capacitance
less than 10 pF must be placed as close as possible to the USIM socket, and the
Ground pin of the ESD protection component is well connected to the power
Ground pin that supplies power to the PCIe Adapter.
3.10 Audio Interface
The MU609 module provides one PCM digital audio interface. Table 3-6 lists the
signals on the digital audio interface.

PCM_CLK: Output when PCM is in master mode;
It is recommended that a TVS be used on the related interface, to prevent electrostatic
discharge and protect integrated circuit (IC) components.
3.11 RF Antenna Connector
The Mini PCIe Adapter provides three antenna connectors (MAIN_ANT, GPS_ANT
and AUX_ANT) for connecting the external antennas.
