RF83/RF83C 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.

RF83/RF83C ASK/OOK Receiver V1.1
4. 8-Pin Options
The standard 16-pin package allows complete control of all configurable features. Some reduced
function 8-pin versions are also available.
For high-volume applications additional customized 8-pin devices can be produced. SWEN, SEL0
and SEL1 pins are internally bonded to reduce the pin count. Pin 6 may be configured as either
SHUT or WAKEB.

Pin Function
Bandwidth Selection Bit 0 (Digital Input): Used in
conjunction with SEL1 to set the desired demodulator filter
bandwidth. See Table 1. Internally pulled-up to VDDRF
RF Power Supply: Ground return to the RF section power
supply.
Antenna (Analog Input): For optimal performance the
ANT pin should be impedance matched to the antenna. See
―Applications Information‖ for information on input
impedance and matching techniques
RF Power Supply: Positive supply input for the RF section
of the IC
Base-Band Power Supply: Positive supply input for the
baseband section (digital section) of the IC
Data Slicing Threshold Capacitor (Analog I/O): Capacitor
connected to this pin extracts the dc average value from the
demodulated waveform which becomes the reference for
the internal data slicing comparator
Not internally connected
Base-Band Power Supply: Ground return to the baseband
section power supply
