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.
