Product Details

The ADF7022 is a very low power, high performance, highly integrated FSK/GFSK transceiver designed for operation at the three io-homecontrol® channels at 868.25 MHz, 868.95 MHz and 869.85 MHz in the license-free ISM band. The ADF7022 is fully compliant to ETSI-300-220, and is based on the popular ADF7020 transceiver with enhanced digital baseband features specifically designed for the io-homecontrol® standard.

ADF7022 features include:

  • Fully integrated io-homecontrol®-compliant protocol covering
    Layer 1, Layer 2, and time critical elements of Layer 3
    Media access
    Master, slave, and beacon modes supported
    Automatic io-homecontrol channel scan
    Automatic CRC, preamble, start byte insertion/check
    UART data encoding as per io-homecontrol
