The module also provides GNSS functionality as a SKU-configuration. Note: Throughout this document, references to RC7611 should be read as RC7611 and RC7611-1 unless variants are called out separately. Accessories A hardware development kit is available for AirPrime RC Series modules. The kit contains hardware components for evaluating and developing with the module, including:

Other accessories Development board Cables Antennas (additional antennas may be required to support all bands) Rev 1.0 Jan 20 5 41113583 2 2: Power Power Supply The host provides power to the AirPrime RC7611 through multiple power and ground pins. The host must provide safe and continuous power at all times; the module does not have an independent power supply, or protection circuits to guard against electrical issues. For detailed pinout and voltage/current requirements of this module, see the AirPrime RC7611 Product Technical Specification. Module Power States The module has four basic power states, as described in Table 2-1. Table 2-1: Supported Power States State Description Active Sleep

Module is fully powered (Linux can be run in the Application Core; modem is on) and operating in one of the following modes:

Full function (WWAN radio active; GNSS radio can be turned on/off)Highest power consumption. Idle mode (WWAN radio on; module is registered on network, but no active connection; GNSS radio can be turned on/off) Airplane mode (WWAN radio off; GNSS radio can be active if allowed by PRI) eDRX (Extended Discontinuous Reception)eDRX mode provides a flexible sleep for the modem, which significantly reduces energy consumption.

Lower power consumption than Active state, but higher than PSM. Application Core is sleeping; modem is in DRX/eDRX. The processor monitors signals

(triggers) that can wake the module. Sleep state can be entered based on USB-SS (if USB is connected to the module), UART_DTR, wake_lock(), configured GPIOs, and QMI exchanges from the modem. Note: On Windows systems, due to limitations of the Windows ECM driver, Sleep state is only supported if ECM is disabled or USB is disconnected. Rev 1.0 Jan 20 6 41113583 Power Table 2-1: Supported Power States State Description PSM (Power Saving Mode) 3GPP Release 12 introduced network support of PSM. PSM allows the module to negotiate, with the network, an extended period during which registration context with the network is retained while the module is unreachable. During the negotiated period, the module enters a very low-power dormant state. After the specified period, the modem and application processors boot up and the modules sends a TAU (Tracking Area Update) to the network. After sending the TAU, the module remains active to allow any pending data to be exchanged with the network. Then, after a negotiated period of inactivity, the module automatically returns to PSM to repeat the cycle. OFF Module is OFF (no power to the system). Apply power for system to go to:

dations 4 This section describes general routing constraints and recommendations for the AirPrime RC7611. Note: This is a non-exhaustive list of suggested design guidelines. The developer is respon-

sible for deciding whether to implement these guidelines. General Rules and Recommendations Clock and other high-frequency digital signals (e.g. serial buses) should be routed as far as possible from the modules analog signals. If the application design makes it possible, all analog signals should be separated from digital signals by a ground trace on the PCB. Tip: Avoid routing any signals under the module on the application board. PCB Layout Recommendations Ground pads should be re-flowed on to the host PCB with < 30% voiding to allow effective heat dissipation. Power Supply When designing the power supply, make sure that VBAT_BB/VBAT_RF meet the requirements listed in the AirPrime RC7611 Product Technical Specification. Careful attention should be paid to the following:

Power supply qualityPFM, or PSM systems should be avoided; Low ripple, linear regulation or PWM converters are preferred for low noise. Capacity to deliver high current peaks in a short time (for pulsed radio emission) VBAT_BB/VBAT_RF must support peak currents with an acceptable voltage drop that guarantees the minimum required VBAT_BB/VBAT_RF value. VBAT_BB/VBAT_RF signal pads must never exceed the maximum required VBAT_BB/VBAT_RF value, otherwise the modules power amplifier and GPS chipset may be severely damaged. A weakly-designed (not robust) power supply could affect EMC performance, the emission spectrum, and the phase error and frequency error.

Rev 1.0 Jan 20 10 41113583 Routing Constraints and Recommendations Antenna Sierra Wireless strongly recommends working with an antenna manufacturer either to develop an antenna adapted to the application, or to adapt an existing solution to the application. For information on routing constraints for the RF circuit, see RF Circuit on page 12. PCB Specifications for the Application Board Sensitive signals (such as audio, UIM, and clocks) should be protected by ground planes/fills. Routing sensitive signals close to noisy signals could result in noise being coupled. Recommended PCB Land Pattern Refer to AirPrime RC Series Customer Process Guidelines, available at http://

source.sierrawireless.com. Routing Constraints Power Supply If the following design recommendations are not followed, phase error (peak) and power loss could occur.

Since the maximum peak current can reach 2.5 A, Sierra Wireless strongly recommends having a large width for the layout of the power supply signal (to avoid voltage loss between the external power supply and VBAT_BB/

VBAT_RF. Figure 4-1: Power Supply Routing Example Rev 1.0 Jan 20 11 41113583 Hardware Integration Guide Note: Figure 4-1 shows separate traces for VBAT_BB and VBAT_RF. If VBAT_BB and VBAT_RF share a single power supply, these traces should be connected.

Note: For optimal decoupling, place the capacitors on the underside of the board, directly under the pins. Filtering capacitors (100 nF to 1500 F) are recommended near the modules power supply. Attention should be paid to the ground trace or the ground plane on the appli-

cation board for the power supply that supplies the module. The ground trace or ground plane, as well as the VBAT trace, must be able to support current peaks. If the ground trace between the module and the power supply is a copper plane, make sure it is a solid plane. Design routing to make sure total line impedance does not exceed 10 m @ 217 Hz. Ground Plane Connection The AirPrime RC7611 requires a solid, central ground plane (with solder mask defined pads) located directly under the module. This will:

Ensure high current signal returns Provide heat dissipation under higher operating temperatures The ground plane should be connected (with vias) to the reference ground layer of the application board. UIM Interface The length of the tracks between the AirPrime RC7611 and the UIM socket should be as short as possible. Maximum recommended length is 10cm. ESD protection is mandatory on the UIM lines unless there is no physical access to the UIM. The decoupling capacitor(s) should be placed as close as possible to the UIM card connector for the UIM1_VCC signal. RF Circuit The RF signal must be routed on the application board using tracks with a 50 characteristic impedance. The characteristic impedance depends on the dielectric, the track width and the ground plane spacing. It is recommended to use stripline design if the RF path is fairly long (more than 3 cm), since microstrip design is not shielded. Consequently, the RF (transmit) signal may interfere with neighboring electronic circuits. In the same way, the neighboring electronics (micro-controllers, etc.) may interfere with the RF

(receive) signal and degrade the reception performance. Rev 1.0 Jan 20 12 41113583 Routing Constraints and Recommendations USB Interface When the USB interface is externally accessible, ESD protection is required on the USB_VBUS, USB_D+, and USB_D- signals. Thermal Considerations When transmitting, the AirPrime RC7611 can generate significant amounts of heat (due to the internal Power Amplifier) that must be dissipated in the host device for safety and performance reasons. The amount of thermal dissipation required depends on the following factors:

Supply voltageMaximum power dissipation for these modules can be up to 3 W at voltage supply limits. UsageTypical power dissipation values depend on the location within the host, amount of data transferred, etc.

To enhance heat dissipation:

Maximize airflow over / around the module

Locate the module away from other components that generate heat Ensure the module is connected to a solid ground plane EMC and ESD Recommendations EMC tests must be performed on the application as soon as possible to detect any potential problems.

When designing, special attention should be paid to:

Possible spurious emissions radiated by the application to the RF receiver in the receiver band ESD protectionTypically, ESD protection is mandatory for externally acces-

sible signals, including:

VBAT_RF/VBAT_BB UIM (if accessible from outside) Serial link USB Antennas Length of the UIM interface lines (preferably <10 cm) Length of the HSIC interface lines (<10 cm, as required by the HSIC specifi-

cation)

EMC protection on audio input/output (filters against 900 MHz emissions)

Ground plane: Sierra Wireless recommends a common ground plane for

analog/digital/RF grounds Note: The AirPrime RC7611 does not include any protection against over-voltage. The host device must provide adequate ESD protection on digital circuits and antenna ports as detailed in the following table. Rev 1.0 Jan 20 13 41113583 Hardware Integration Guide Note: The level of protection required depends on your application.
