SPIRIT1QTR

Very low-power RF transceiver intended for RF wireless applications. It can perform cyclic redundancy checks on the data as well as FEC encoding/decoding on the packets. It provides an optional automatic acknowledgement, retransmission and timeout protocol engine in order to reduce overall system costs by handling all the high-speed link layer operations. Typically used at AMR (automatic meter reading), home and building automation, WSN (wireless sensors network), industrial monitoring and control, wireless fire and security alarm systems and point-to-point wireless link.

• 2-FSK, GFSK, MSK, GMSK, OOK and ASK modulation schemes
