Product Description
The RF2968 is a monolithic integrated circuit intended for
use as a low-cost FSK transceiver in
Bluetooth
applica-
tions. The device is provided in 32-lead plastic LPCC
packaging and is designed to provide a fully-functional
FSK transceiver. The chip is intended for
Bluetooth
appli-
cations in the 2.4GHz to 2.5GHz ISM band. The IF and
demodulation sections of the chip require no external fil-
ters or discriminators. The chip also features an image
reject front end and a fully programmable synthesizer
with integrated oscillator circuitry. Self-calibrating RX and
TX IF circuitry optimizes link performance and eliminates
manufacturing variations.
