HFA3824A
August 1998 File Number 4459.2
Direct Sequence Spread Spectrum
Baseband Processor
The Intersil HFA3824A 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.
The HFA3824A has on-board ADC’s 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 optional data scrambling
capability, are combined with a programmable PN sequence
of up to 16 bits. Built-in flexibility allows the HFA3824A to be
configured 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
provides Clear Channel Assessment (CCA) to avoid data
collisions and optimize network throughput. The HFA3824A
is housed in a thin plastic quad flat package (TQFP) suitable
for PCMCIA board applications.
