Overview
RF83//RF83C/RF83L/RF83CL ASK/OOK Receiver V2.
0 RF83/RF83C/RF83L/RF83CL 300~440MHz ASK/OOK Receiver General Description The RF83/RF83C 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 the RF83C is a reduced function set part packaged in 8-pin packaging .
The RF83/RF83C operating voltage range is 3.
6V-5.
5V, Their low voltage counterparts are RF83L/RFM83CL at 2.
1V-3.
6V.
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/RF83C, so no external filters are necessary.
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.
