2.2.3.2 Reference circuit
The reference circuit of USB interface is shown in figure 2-7.
1）For getting the steady-going USB power supply, it is recommended that a 10uF（C406）filter capacitor and a 22pF
（C407）filter capacitor should be used.
2）For reducing the BER of USB transmission, it is recommended to add a resistor with values below 10Ωto the
DM and DP in USB interface. Just like the resistors R408 and R409 in figure 2-7.

Page 12 of 32
3）For avoiding the electro-static in USB interface, it is recommended to use the ESD element. Just like the voltage
dependent resistors RV406, RV407 and RV408 with the static capacitance values below 3pF.
Figure 2-7 The reference circuit of USB interface
4）The USB interface input the voltage from USB_IN .For keeping the USB in U9507E module working unfailingly,
a voltage protection circuit should be added by user between the USB_IN of USB interface and the USB_VBUS PIN of
U9507E. It is shown in figure 2-8 with the red circle 2. In the voltage protection circuit, D603 is a Zener diode with a
breakdown voltage value of 5.1v which could keep the voltage on the USB_VBUS PIN of U9507E not more than
5.1v. D602 is a Schottky Diode, and R621 is a resistor with the value 1KΩ. On the other hand the voltage coming
from the USB_IN also could be converted by using a DC/DC converter to 3.6v and then be sent to VBAT PIN of
U9507E. It is shown in figure 2-8 with the red circle 1.
