Wistron NeWeb Confidential Document 4 1. General Description The AVMD7540-SWA5 module is a complete radio module solution containing all the necessary HW and FW to provide a system-integration ready, multichannel wireless HD audio solution. The module is comprised of a AV7540 IC combined with RF front-end circuits (RF PA + balun + filter + RF switch), flash memory, crystal, and passive components. It is FCC certified and ready for operation with U.FL connectors. The module provides a convenient set of digital I/O interfaces for digital audio through an I2S port, host MCU control through an SPI or I2C interface and optional GPIO for various control and indicator functions. The module is a card edge style using the 36 pin PCIe card edge connection method to save space and cost in connecting to the main board. FCC & IC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the exemption from the routine evaluation limits in section 2.5 of RSS 102. 1. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 2. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters from user and bystanders. The device meets the exemption from the routine evaluation limits in section 2.5 of RSS 102 Wistron NeWeb ® Wistron NeWeb Corporation 20 Park Avenue II, Hsinchu Science Park, Hsinchu 308, Taiwan, R.O.C.
