RF83A//RF83C ASK/OOK Receiver V1.1

RF83A/RF83C

General Description

300~440MHz ASK/OOK Receiver

The RF83A/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 RF83A is a fully featured part in 16-pin

packaging and the RF83C is a reduced function set part

packaged in 8-pin packaging .

The RF83A 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 RF83A 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 RF83A/RF83C, so no

external filters are necessary.

The RF83A offer two modes of operation; fixed-mode

(FIX) and sweep-mode (SWP). In fixed mode the RF83A functions as a conventional super-heterodyne

receiver. In sweep mode the RF83A sweeps a wider RF spectrum. Fixed-mode provides better selectivity and

sensitivity performance and sweep mode enables the RF83A to be used with low cost, imprecise transmitters.
