Operation Description Receiver first uses SPRF2413A/SPRF2423A chip to perform RF transceiver, mi xing, demodulating and passing the data.SPRF2413A/SPRF2423A chip decode these data with its decoding control unit and passes decoded data to inside US B interface unit. USB interface unit passes all these data to the computer USB processor. The USB processor then processes all incoming instruction. The po wer of the receiving unit is provided by PC USB. SPRF2413A/SPRF2423A u ses a 16MHz crystal.
