1. Introduction The Sierra Wireless AirPrime MC7354B PCI Express Mini Card is a compact, lightweight, wireless LTE-, UMTS-, CDMA- and GSM-based modem. It provides LTE, EVDO Rel 0, EVDO Rel A, DC-HSPA+, HSPA+, HSDPA, HSUPA, WCDMA, GSM, GPRS, EDGE and GNSS connectivity for networking, and M2M applications over several radio frequency bands. The device also supports 2G/3G roaming, subject to carrier provisioning. 1.1.
2. Power Interface 2.1. Power Supply The host device must provide power to the MC7354B mini card over pins 2, 24, 39, 41 and 52 (VCC) as detailed in the following table. Table 1. Power Supply Requirements Signal Name Pin VCC 2, 24, 39, 41, 52 GND 4, 9, 15, 18, 21, 26, 27, 29, 34, 35, 37, 40, 43, 50 Specification Minimum Typical Maximum Unit Voltage range 3.0 3.3 3.
Hardware Integration Guide 2.3. Power Interface Power States The MC7354B mini card has four power states as detailed in the following table. Table 3.
3. RF Integration 3.1. Table 4.
Hardware Integration Guide 3.2. RF Integration Ground Connection When connecting the mini card to system ground: Prevent noise leakage by establishing a very good ground connection to the mini card through the host connector. Minimize ground noise leakage into the RF. Depending on the host board design, noise could potentially be coupled to the mini card from the host board.
Hardware Integration Guide 3.5. RF Integration RF Desense Sources Common sources of interference that may affect the module’s RF performance (RF desense) which include: Power supply noise Can lead to noise in the RF signal Module power supply ripple limit <= 100 mVp-p 1 Hz–100 kHz Interference from other embedded wireless devices Any harmonics, sub-harmonics, or cross-products of signals that fall in the module’s Rx range may cause spurious response, resulting in decreased Rx performance.
4. Audio Interface The MC7354B supports a PCM/I2S digital audio interface using a dedicated serial link for digital audio data; all other signals, such as subcoding and control, are transmitted separately. The audio interface can be switched from PCM to I2S and vice versa via AT commands. Table 5.

Hardware Integration Guide Regulatory Information Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is open. The MC7354B modem may be used normally at this time. 5.3. Important Compliance Information for North American Users The MC7354B modem has been granted modular approval for mobile applications. Integrators may use the MC7354B in their final products without additional FCC/IC (Industry Canada) certification if they meet the following conditions.
