Product Description

The AWI5800 is an integrated single chip transmitter designed for analog A/V sender and wideband digital FSK transmitter operating in the 5.8GHz ISM band. The transmitter consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator and a stereo audio modulator. The IC is provided in 32-lead QFN5X5 package and is designed to provide a fully functional FM/FSK transmitter.

Main Features

3.3V power Supply7 channel operation for analog A/V sender and digital FSK transmission applicationsChannel select by use of either a DIP switch or a tact switch for a set of pre-defined frequenciesProgrammable user-defined channel frequencies by use of the 3-wire serial interfaceTwo audio sub-carriers generated with PLL for high frequency accuracy and stability

MSB of the 3 Bits CH Selection PIN.If PIN5(SW) is grounded, PIN6 is normal high and enabled when pull low.If use PIN5(SW) to select channel, PIN6 outputs the selected channel status according to the operation of PIN5(SW). A series resistor R24 of 47KΩ and a shunt capacitor C42 of 39pF are recommended. (See Note2)

BIT26

If PIN23(SEL) is unconnected (Internal pull high), the channel can be selected by either PIN5(SW) or the settings of BIT0, BIT1, BIT2 (when PIN5 is grounded) from a set of pre-defined channel frequencies. PIN5(SW) is normal high and each pull low will advance one channel in the pre-defined channel sequence (CH1, CH2 …, CH7, CH1 …) (See Note2)
