General Description:
The RF83 is a single chip ASK/OOK (ON-OFF Keyed) RF receiver IC. This device is a true "antenna-in to data-out” monolithic device. All RF and IF tuning are accomplished automatically within the IC which eliminates manual tuning and reduces production costs. The result is a highly reliable yet low cost solution.
The RF83 is a fully featured part in 16-pin packaging and a same part packaged in 8-pin packaging with a reduced feature set.
The RF83 provides two additional functions, (1) a Shutdown pin, which may be used to turn the device off for duty-cycled operation, and (2) a “Wake-up” output, which provides an output flag indicating when an RF signal is present. These features make the RF83 ideal for low and ultra-low power applications, such as RKE and remote controls.
All IF filtering and post-detection (demodulator) data filtering is provided within the RF83, so no external filters are necessary. One of four demodulator filter bandwidths may be selected externally by the user.
The RF83 offer two modes of operation; fixed-mode (FIX) and sweep-mode (SWP). In fixed mode the RF83 functions as a conventional super-heterodyne receiver. In sweep mode the RF83 sweeps a wider RF spectrum. Fixed-mode provides better selectivity and sensitivity performance and sweep mode enables the RF83 to be used with low cost, imprecise transmitters.
