Description
The AT48802 Spread-Spectrum Signal Processor (SSSP) chip from Atmel handles all PN code generation, synchronization, and handshaking required for either station (handset or base station) of a time division duplex direct sequence spread-spectrum cordless telephone. The AT48802 supports RF spreading and despreading for the best rejection of interference.
