HFA3860A
Direct Sequence Spread Spectrum
Baseband
The Intersil HFA3860A Direct
Sequence Spread Spectrum (DSSS)
baseband processor is part of the
PRISM 2.4GHz radio chipset, and
contains all the functions necessary for
a full or half duplex packet baseband transceiver.
The HFA3860A has on-board A/Ds for analog I and Q inputs,
for which the HFA3724/6 IF QMODEM is recommended.
Differential phase shift keying modulation schemes DBPSK
and DQPSK, with data scrambling capability, are available
along with M-Ary Bi-Orthogonal Keying to provide a variety
of data rates. Built-in flexibility allows the HFA3860A to be
configured through a general purpose control bus, for a
range of applications. A Receive Signal Strength Indicator
(RSSI) monitoring function with on-board 6-bit A/D provides
Clear Channel Assessment (CCA) to avoid data collisions
and optimize network throughput. The HFA3860A is housed
in a thin plastic quad flat package (TQFP) suitable for
PCMCIA board applications.
