It can receive FSK and ASK modulated signals. The IC is designed for gen- eral purpose applications for example in the European bands at 433MHz and 868MHz or for similar applica- tions in North America or Asia, for example at 315MHz or 915MHz. The receiver has been optimized for consumer and industrial applications. 39010 71121 Page 2 of 29 Data Sheet Rev. 011 Jun/12 VCC LNASEL MIXO RFSEL VEE IFAP DTAO IFAN CLKO MODSEL IFSEL SLCSEL DF2 ROI
