HFA3860
11 Mbps Direct Sequence Spread
Spectrum Baseband Processor
The Intersil HFA3860 Direct Sequence
(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 for applications requiring 11 Mbps performance.
The HFA3860 has on-board A/Ds for analog I and Q inputs, for
which the HFA3726 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 HFA3860 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)toavoiddatacollisionsandoptimizenetworkthroughput.
The HFA3860 is housed in a thin plastic quad flat package
(TQFP) suitable for PCMCIA board applications.
