1. Introduction The Sierra Wireless AirPrime SL9090 soldered-down module forms the radio component for the products in which it is embedded. Module-specific performance and physical characteristics are described in the corresponding product specification document. Note: An understanding of network technology, and experience in integrating hardware components into electronic equipment is assumed. 1.1.
2. Power Interface 2.1. Power Supply The host device must provide power to the AirPrime soldered-down module over pins 42 and 44 (VCC_3V6) as detailed in the following table. Table 1. Power Supply Requirements Requirement Type Value Power Supply 3.6V (nominal) Voltage Range (VMIN – VMAX) 3.4V – 4.
Power Interface 2.3. Power States The SL9090 module has five power states as detailed in the following table. Table 3.
3. RF Integration 3.1. Supported RF Bands Table 4.
RF Integration 3.1.1. Ground Connection Guidelines When connecting the module to system ground: Prevent noise leakage by establishing a very good ground connection to the module through the host connector. 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.
RF Integration 3.3. 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 The AirPrime SL9090 embedded module only supports digital audio interface (I2S) as summarized in the following tables. Refer to document [2] AirPrime SL9090 Product Technical Specification and Customer Design Guidelines for detailed information about the digital audio interface. Table 5. I2S Audio Interface Features Feature Details Implementation I2S interface supported to interface with external codec Power 1.
5. Regulatory Information 5.1. Important Notice Because of the nature of wireless communications, transmission and reception of data can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost.
Regulatory Information 5.3. Important Compliance Information for North American Users The SL90909 modem has been granted modular approval for mobile applications. Integrators may use the SL9090 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. At least 20 cm separation distance between the antenna and the user’s body must be maintained at all times. 2.
Regulatory Information Stripline and Coplanar design requires having a correct ground plane at both sides. Consequently, it is necessary to add some vias along the RF path. It is recommended to use Stripline design if the RF path is fairly long (more than 3cm), since MicroStrip design is not shielded. Consequently, the RF signal (when transmitting) may interfere with neighbouring electronics (AF amplifier, etc.). In the same way, the neighbouring electronics (micro-controllers, etc.
