PRELIMINARY
HFA3863
Direct Sequence Spread Spectrum
Baseband Processor
The Intersil HFA3863 Direct Sequence
Spread Spectrum (DSSS) baseband
processor is part of the PRISM 2.4GHz
radio chipset, and contains all the
functionsnecessaryforafullorhalfduplex
packet baseband transceiver.
The HFA3863 has on-board A/D’s and D/A for analog I and Q
inputs and outputs, for which the HFA3783 IF QMODEM is
recommended. Differential phase shift keying modulation
schemes DBPSK and DQPSK, with data scrambling capability,
are available along with Complementary Code Keying to provide
avarietyofdatarates.Built-inflexibilityallowstheHFA3863tobe
configured through a general purpose control bus, for a range of
applications.BothReceiveandTransmitAGCfunctionswith7-bit
AGC control obtain maximum performance in the analog
portions of the transceiver. The HFA3863 is housed in a thin
plastic quad flat package (TQFP) suitable for PCMCIA board
applications. It is pin compatible with the HFA3861B.
