1. Introduction The Sierra Wireless MC7350 PCI Express Mini Card is a compact, lightweight, wireless LTE- and CDMA-based modem. It provides LTE and CDMA connectivity for networking, and M2M applications over several radio frequency bands and supports 2G / 3G roaming. 1.1. Hardware Development Components Sierra Wireless manufactures the MC Series Development Kit, a hardware development component that is used to facilitate the hardware integration process.
2. Power Interface 2.1. Power Supply The host device must provide power to the MC7350 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 MC7350 mini card has four power states as detailed in the following table.
3. RF Integration 3.1. Supported RF Bands Table 4. Supported RF Bands Band/Connectivity Data Rates CDMA BC0 (Cellular 800 MHz) CDMA IS-2000 Up to 153 kbps, simultaneous forward and reverse channel CDMA BC1 (PCS 1900 MHz) CDMA IS-856 (1xEV-DO Release A) CDMA BC10 (Secondary 800 MHz) Up to 3.1 Mbps forward channel Up to 1.8 Mbps reverse channel Notes 3G diversity support Circuit-switched data bearers up to 14.
Hardware Integration Guide 3.3. RF Integration Shielding Guidelines The mini card is fully shielded to protect against EMI and to ensure compliance with FCC Part 15 “Radio Frequency Devices” (or equivalent regulations in other jurisdictions). Note: The module shields must NOT be removed. 3.4. Antenna Guidelines When selecting the antenna and cable, it is critical to RF performance to match antenna gain and cable loss. 3.4.1.
Hardware Integration Guide 3.5. RF Integration RF Desense Sources Common sources of interference that may affect the module’s RF performance (RF desense) 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 2 The MC7350 supports a PCM/I S 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 2 can be switched from PCM to I S and vice versa via AT commands. Table 5.

Hardware Integration Guide Regulatory Information 5.3. Important Compliance Information for North American Users Note: Details are preliminary and subject to change. The MC7350 modem has been granted modular approval for mobile applications. Integrators may use the MC7350 modem in their final products without additional FCC / IC (Industry Canada) certification if they meet the following conditions. Otherwise, additional FCC / IC approvals must be obtained. 1.
Hardware Integration Guide Regulatory Information 5. A user manual with the end product must clearly indicate the operating requirements and conditions that must be observed to ensure compliance with current FCC / IC RF exposure guidelines. The end product with an embedded MC7350 modem may also need to pass the FCC Part 15 unintentional emission testing requirements and be properly authorized per FCC Part 15.
