433/868/915MHZ ASK/OOK
RECEIVER
Product Description
The RF2919 is a monolithic integrated circuit intended for
use as a low cost ASK/OOK receiver. The device is pro-
vided in 32-lead plastic packaging and is designed to pro-
vide a fully functional AM receiver. The chip is intended
for applications in the North American 915MHz ISM band
and European 433MHz and 868MHz ISM bands. The
integrated VCO, +64 prescaler, and reference oscillator
require only the addition of an external crystal to provide
a complete phase-locked oscillator for single channel
applications. A data comparator is included to provide
logic level outputs.
