1 1: Introduction Sierra Wireless’ Mini Card modules form the radio component for the products in which they are embedded. Mini Cards are available for use on CDMA and GSM networks, including: Note: Throughout this document, MC57xx and MC87xx refer to the entire suites of CDMA and GSM Mini Cards respectively.
CDMA / GSM Mini Card Hardware Integration Guide Required connectors Note: Contact vendors before choosing your connectors — the numbers included here are for reference only. Choose connectors that are appropriate to your design. When integrating these modules into your host device, you need the following connector types: • RF cable that mates with Hirose U.FL connector (model U.FL #CL331‐0471‐0‐10) • Industry‐standard mating connector for 52‐pin EDGE— some manufacturers include Tyco, Foxconn, and Molex.

Download this document (3GPP TS 27.007) from www.3gpp.org. CDMA 1X Standard Technical requirements for CDMA systems, including details on sleep cycle index (SCI) values. Order this document, CDMA 2000 Series Release A (2000) (document # TIA/EIA/IS-2000 Series, Release A) from www.tiaonline.

MC8775 PCI Express Mini Card Product Specification (Document 2130697) Features, mechanical and electrical specifications, and standards compliance of the MC8775.
2 2: Power Interface Overview of operation Note: This chapter contains information for both the CDMA (MC57xx) and GSM (MC87xx) modules. Information that is unique to specific module types is clearly identified. The module is designed to use a 3.3V (nominal) power supply, provided by the host. It is the host’s responsibility to provide safe and continuous power to the module at all times; the module does NOT have an independent power supply, or protection circuits to guard against electrical issues.
CDMA / GSM Mini Card Hardware Integration Guide Note: ESD protection is highly recommended for the USIM / RUIM connector at the point where the contacts are exposed, and for any other signals from the host interface that would be subjected to ESD by the user of the product. Module power states Note: The module unit defaults to the Normal state when VCC3.3 is first applied in the absence of W_Disable# control. The module has four power states: • Disconnected No power to the module.
Power Interface Normal state Note: This is the default state when VCC3.3 is first applied in the absence of W_Disable# control. This is the active state of the module. In this state: • The module is fully powered. • The module is capable of placing / receiving calls or estab‐ lishing data connections on the wireless network. • The USB interface is fully active. Low power mode In this state, RF (both Rx and Tx) is disabled in the module, but the USB interface is still active.
CDMA / GSM Mini Card Hardware Integration Guide The module automatically enters slotted sleep mode when there is no transmission or reception occurring (SCI = 2). Transmit power is assumed to be +3 dBm. 14 2130114 Values in this guide are summarized from the product specification documents (PSDs) - the PSD takes precedence.
3 3: RF Integration The MC87xx operates on the frequencies detailed in Table 3‐1.
CDMA / GSM Mini Card Hardware Integration Guide Figure 3-1: Antenna connection points and mounting holes Ground connection When connecting the module to system ground: • Prevent noise leakage by establishing a very good ground connection to the module through the host connector. • Connect to system ground using the two mounting holes at the top of the module (as shown in Figure 3‐1). • Minimize ground noise leakage into the RF.
RF Integration Antenna and cabling Note: Values in this guide are taken from the appropriate product specification documents (PSDs) (listed in Related documents, page 8) — in the case of a discrepancy between this document and the relevant PSD, use the value listed in the PSD. When selecting the antenna and cable, it is critical to RF perfor‐ mance to match antenna gain and cable loss.
CDMA / GSM Mini Card Hardware Integration Guide Interference and sensitivity Note: These modules are based on ZIF (Zero Intermediate Frequency) technologies; when performing EMC (Electromagnetic Compatibility) tests, there are no IF (Intermediate Frequency) components from the module to consider.
RF Integration Device-generated RF Note: The module can cause interference with other devices such as hearing aids and onboard speakers. Wireless devices such as the Mini Card transmit in bursts (pulse transients) for set durations (RF burst frequencies). Hearing aids and speakers convert these burst frequencies into audible frequencies, resulting in audible noise. All electronic computing devices generate RF interference that can negatively affect the receive sensitivity of the module (RF desense).
CDMA / GSM Mini Card Hardware Integration Guide 20 2130114 In the event of a discrepancy in values between this guide and the Product Specification Document (PSD), the PSD takes precedence.
4 4: Host / Module Communication Interface This chapter provides information about the Host‐Module communication interface (USB interface) and lists the extended AT commands that may be useful for hardware integration testing. Note: On any given interface (USB, USIM/RUIM, etc.), leave unused inputs and outputs as no-connects. LED output The module drives the LED output according to the PCI‐ Express Mini Card specification (summarized in Table 4‐1, below).

CDMA / GSM Mini Card Hardware Integration Guide Important compliance information for North American users The MC57xx / MC87xx modem has been granted modular approval for mobile applications. Integrators may use the MC57xx / MC87xx 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.
Regulatory Information · 5. For MC8781: This device contains FCC ID: N7NMC8781 This equipment contains equipment certified under IC: 2417C‐MC8781 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.
