4 Page 4 Rev.: Product The AWI58 is an integrated single chip receiver designed for analog A/V sender and wideband digital FSK receiver operating in the 5.8GHz ISM band. The receiver IC consists of a fully integrated frequency synthesizer, LNA, Mixer, IF Amplifier, PLL FM Demodulator, Audio Demodulator and Audio OP Amplifier. The IC is provided in 48-lead QFN7X7 package and is designed to provide a fully functional FM/FM receiver. Main Features 3.6V power Supply (Typical) Wideband PLL demodulator for adjustment-free production 7 channels operation for analog A/V sender and digital FSK transmission applications Channel select by use of either a DIP switch or a tact switch for a set of pre-defined frequencies Integrated stereo Sound Demodulator and Audio OP Amplifiers Pin Configurations

PIN7(SW) is normal high and each pull low will advance one channel in the predefined channel sequence (CH1, CH, CH7, CH1 ) See Note MSB of the 3 Bits CH Selection PIN. 8 BIT If PIN7(SW) is grounded, PIN8 is normal high and enabled when pull low. If use PIN7(SW) to select channel, PIN8 outputs the selected channel status according to the operation of PIN7(SW). A series resistor R30 of 47K and a shunt capacitor C6 of 0.068uF are recommended. See Note
