4.6 USB 2.0
SIM7600E-PCIE is compliant with USB 2.0 specification. It supports full-speed and high- speed when acting as a
peripheral device.
SIM7600E-PCIE can be used as a USB device. SIM7600E-PCIE supports the USB suspend and resume
mechanism which can reduce power consumption. If there is no data transmission on the USB bus,
SIM7600E-PCIE will enter suspend mode automatically, and will be resumed by some events such as voice call
or receiving SMS, etc.

Figure 10: USB Reference Circuit
Because of the high bit rate on USB bus, please pay more attention to the influence of the junction capacitance
of the ESD component on USB data lines. Typically, the capacitance should be less than 1pF. It is recommended
to use an ESD protection component such as ESD9L5.0ST5G provided by On Semiconductor
(
www.onsemi.com ).
Note;
1. The USB_DN and USB_DP nets must be traced by 90Ohm+/-10% differential impedance.
2. The USB VBUS of the module is connected to VBAT internally, so there is no need to connect externally.
3. The SIM7600E-PCIE has two kinds of interface (UART and USB) to connect to host CPU. For example,
on windows XP operating system, USB interface is mapped to 4virtual ports: “SimTech HS-USB Audio
9001”, “SimTech HS-USB AT port 9001”, “SimTech HS-USB Diagnostics 9001”, “SimTech HS-USB
NMEA 9001”.
