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.
