2.2 U9507A interface application
U9507A supplies multifold functional interface by a Mini PCIe Interface, such as , USIM card interface, USB interface,
audio interface*, UART interface*, PCM（Pulse Code Modulation）interface*and power supply interface and so on.
The detail information will be given in the follow sections.
2.2.1 RF antenna interface
The impedance of RF antenna is 50Ω.
The three connector is on the top of U9507A;
For minimizing the wasting of RF cable, user should pay more attention to make choice. We suggest choosing the cable
that satisfies:
• GSM900/LTE BAND5/LTE Band2/LTE BAND 4/LTE BAND12/WCDMA
BAND5/WCDMA BAND8<0dB
• DCS1800/LTE Band13/LTE Band17/WCDMABAND1 <0dB
• LTE Band28 <0dB
And the antenna should satisfy the table below：

Interface to RF Connector
Figure 2-11 shows a sample connection of a module’s antenna pad at the bottom layer of the module PCB with an
application PCB’s coaxial antenna connector .Line impedence depends on line width, but also on other PCB
characteristics like dielectric, height and layer gap. The sample stripline width of 0.33mm is recommended for an
application with a PCB layer stack resembling the one of the PLS62-W evaluation board shown in Figure 12.For
different layer stacks the stripline width will have to be adapted accordingly.

2.2.4.2 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.
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.

Page 15 of 33
Figure 2-13 The reference circuit of USB interface
4）The USB interface input the voltage from USB_IN .For keeping the USB in U9507A 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
U9507A. 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 U9507A 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
U9507A. It is shown in figure 2-8 with the red circle 1.

DALA, CLK and RST. Just like the resistors R307, R308 and R309 in figure 2-8.
3）For avoiding the electro-static in USIM socket, it is recommended to use the ESD element to the DATA，CLK and
VCC. Just like the voltage dependent resistors RV301, RV302, RV303 and RV304 in figure 2-8. And the ESD
element should close to the USIM socket as close as possible.
4）For getting the more smooth USIM power supply, it is recommended to use the filter capacitors. Just like C311 and
C312 in figure 2-8, and their reference values are 33pF and 100nF.
5）In order to remove the unwanted peak signal and the elimination high frequency interference which produces on RST
