Description
The Atmel AT86RF210 Z-Link
TM
Transceiver is a fully integated, low-cost ZigBee
TM
transceiver capable of transmitting and receiving BPSK modulated digital data over a
frequency range of 868 MHz and 902928 MHz using a minimum number of external
components. It combines excellent RF performance with low cost, small size and low
current consumption. The AT86RF210 includes a crystal stabilized Fractional-N syn-
thesizer, BPSK transmitter and receiver, and full Direct Sequence Spread Spectrum
Signal (DSSS) processing, including spreading and despreading. The device is fully
compatable with IEEE 802.15.4 and ZigBee standards. It includes internal voltage
regulation and battery monitoring circuitry and requires a minimum number of external
support components.
