NL952 module uses PCIe interface, according to the PCIe specification, the PCIe Vmain should be used as the +3.3V power source, not the Vaux. The Vaux is the PCIe backup power source and it is not sufficient as the power supply. In addition, the DC/DC power supply other than PCIe ports should not be used as the external power cannot control the module status through the PCIe protocol. 36 48 Power Supply Figure 3-2:

LDO or DC/DC power supply requires the capacitor of no less than 440uF The capacitor for battery power supply can be reduced to 100~200uF Filter out the interference generated from the clock and digital signals Filter out low frequency band RF interference Filter out medium/high frequency band RF interference The stable power supply can ensure the normal operation of NL952 module; and the ripple of the power supply should be less than 300mV in design. Because module support 5CA download, when module operates with the maximum data transfer throughput, the peak current can reach to upper 2500mA. It requests the power source voltage should not be lower than 3.3V, otherwise module may shut down or restart. The power supply requirement is shown in Figure 3-3:

PCIe can achieve the maximum transmission rate of 5 GT/s, and must strictly follow the rules below in PCB Layout:

AP end;

The differential signal pair lines shall be parallel and equal in length;

The differential signal pair lines shall be short if possible and be controlled within 15 inch(380 mm) for The impedance of differential signal pair lines is recommended to be 100 ohm, and can be controlled to 80120 ohm in accordance with PCIe protocol;

It shall avoid the discontinuous reference ground, such as segment and space;

When the differential signal lines go through different layers, the via hole of grounding signal should be in close to that of signal, and generally, each pair of signals require 1-3 grounding signal via holes and the lines shall never cross the segment of plane;

Try to avoid bended lines and avoid introducing common-mode noise in the system, which will influence the signal integrity and EMI of difference pair. As shown in Figure 3-13, the bending angle of all lines should be equal or greater than 135, the spacing between difference pair lines should be larger than 20mil, and the line caused by bending should be greater than 1.5 times line width at least. When a serpentine line is used for length match with another line, the bended length of each segment shall be at least 3 times the line width (3W). The largest spacing between the bended part of the serpentine line and another one of the differential lines must be less than 2 times the spacing of normal differential lines (S1<2S);

Figure 3-13 Requirement of PCIe Line The difference in length of two data lines in difference pair should be within 5mil, and the length match is required for all parts. When the length match is conducted for the differential lines, the designed position of correct match should be close to that of incorrect match, as shown in Figure 3-14. However, there is no specific requirements for the length match of transmit pair and receiving pair, that is, the length match is only required in the internal differential lines rather than between different difference pairs. The length match should be close to the signal pin and pass the small-angle bending design. Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved.

The SIM card hot-plugging function can be configured by AT+MSMPD command, and the description for AT command as shown in the following table:

AT Command Function Description Hot-plugging Detection AT+MSMPD=1 Enable AT+MSMPD=0 Disable Note:

Default value, the SIM card hot-plugging detection function is enabled. The module can detect whether the SIM card is inserted or not through the SIM_DETECT pin state. The SIM card hot-plugging detect function is disabled. The module reads the SIM card when starting up, and the SIM_DETECT status will not be detected. By default, SIM_DETECT is active-high, which can be switched to active-low by the AT command. Please refer to the AT Commands Manual for the AT command. USIM Design The SIM card circuit design shall meet the EMC standards and ESD requirements with the improved capability to resist interference, to ensure that the SIM card can work stably. The following guidelines should be noted in case of design:

The SIM card slot placement should near the module as close as possible, and away from the RF antenna, DC/DC power supply, clock signal lines, and other strong interference sources. The SIM card slot with a metal shielding housing can improve the anti-interference ability. The trace length between the SIM card slot and the module should not exceed 100mm, or it could reduce the signal quality. The UIM_CLK and UIM_DATA signal lines should be isolated by GND to avoid crosstalk interference. If it is difficult for the layout, the whole SIM signal lines should be wrapped with GND as a group at The filter capacitors and ESD devices for SIM card signals should be placed near to the SIM card slot, and the ESD devices with 22~33pF capacitance should be used. least.

Modular A roval Re uest FCC (KDB 996369 DO1 & Part 15.212) FCC ID: ZMONL952NA Items to be covered by Single 1. The modular transmitter must have its own RF shielding. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. The modular transmitter must have its own power supply regulation. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204{b)(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits ic--1e0 | (RS aT eee aOR AMM EMule Mey Flore The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number in accordance with 15.212 (a)(1)(vi)(A) / (B). The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Com liance with these requirements must be assured. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 1.1310, 2.1091, 2.1093, and specific Sections of Part 15, including 15.319{i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. in addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance. Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance.
