Direct Sequence Spread
Spectrum Baseband
Processor
The Intersil HFA3824 Direct Sequence
(DSSS) baseband processor is part of the PRISM™
2.4GHz radio chipset, and contains all the functions neces-
sary for a full or half duplex packet baseband transceiver.
The HFA3824 has on-board ADC’s for analog I and Q
inputs, for which the HFA3724/6 IF QMODEM is recom-
mended. Differential phase shift keying modulation schemes
DBPSK and DQPSK, with optional data scrambling capabil-
ity, are combined with a programmable PN sequence of up
to 16 bits. Built-in flexibility allows the HFA3824 to be config-
ured through a general purpose control bus, for a wide range
of applications. A Receive Signal Strength Indicator (RSSI)
monitoring function with on-board 6-bit 2 MSPS ADC pro-
vides Clear Channel Assessment (CCA) to avoid data colli-
sions and optimize network throughput. The HFA3824 is
housed in a thin plastic quad flat package (TQFP) suitable
for PCMCIA board applications.
