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. • MC5725 / MC5725V / MC5727 / MC5727V / MC5728V—Operate on CDMA networks using the CDMA IS‐95A, 1X, and 1xEV‐DO (IS‐856) network standards, and support GPS.
CDMA and GSM / UMTS Mini Card Hardware Integration Guide For instructions on setting up the UDK, see PCI Express Mini Card Dev Kit Quick Start Guide (Document 2130705). 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 cables that mate with Hirose U.FL connectors (model U.

2 2: Power Interface Overview of operation Note: This chapter contains information for 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 and GSM / UMTS Mini Card Hardware Integration Guide MC5728V has placeholders for additional ESD devices, for cases where the device must, per customer requirements, meet the higher Human Body Model (+/‐1kV) ESD rating. Specific recommendations are provided where needed in this guide, however, the level of protection required depends on your application.
Power Interface Off state In this state, the host is powered up and the module is powered down (but still connected to the power source). The host keeps the module powered off by driving the W_Disable# signal low. In this state, the module draws minimal current. 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.

3 3: RF Integration The MC87xx operates on the frequencies detailed in Table 3‐1. Table 3-1: MC87xx— RF parameters Product Rev 1.12.4 Oct.

RF Integration 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. Depending on the host board design, noise could potentially be coupled to the module from the host board.
CDMA and GSM / UMTS Mini Card Hardware Integration Guide Shielding The module 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.
RF Integration • Antenna cables should be routed, if possible, away from noise sources (switching power supplies, LCD assemblies, etc.). If the cables are near the noise sources, the noise may be coupled into the RF cable and into the antenna. Disabling the diversity antenna • MC57xx — If your host device is not designed to use the MC57xx module’s diversity antenna, terminate the interface with a 50 Ω load.
CDMA and GSM / UMTS Mini Card Hardware Integration Guide The severity of this interference depends on the closeness of the other antennas to the module’s antenna. To determine suitable locations for each wireless device’s antenna, thoroughly evaluate your host device’s design. Device-generated RF All electronic computing devices generate RF interference that can negatively affect the receive sensitivity of the module.

CDMA and GSM / UMTS Mini Card Hardware Integration Guide The typical handset sidetone is 12 dB below transmit voice levels. For Handset and Headset mode, the threshold of pain (+120 dBSPL) must not be exceeded at the maximum volume setting. A good target for the medium volume setting is +94 dBSPL, as this is a typical level for conversational speech. Most audio gain should be added to the host audio front end (within the PDA style codec gain blocks or amplifiers between the host codec and transducers).

Audio Interface • Audio path mixing—required for voice memo recording and playback via multiple audio paths • Transducer interface—host provides acoustic drivers, must occur outside of path switching and mixing These functions can be performed in either host or module codec, depending on balance of component selection and engineering resources: • Volume settings—adjustable gain settings based on user interface selections • Sidetone—careful placement of sidetone gain control is required to prevent the need
