ADVANCE INFORMATION Data Sheet
HFA3861
July 1999 File Number 4699.1
Direct Sequence Spread Spectrum
Baseband Processor
The Intersil HFA3861 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 HFA3861 has on-board A/D’s 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 a variety of data rates. Built-in flexibility
allows the HFA3861 to be configured through a general
purpose control bus, for a range of applications. Both
Receive and Transmit AGC functions with 7-bit AGC control
obtain maximum performance in the analog portions of the
transceiver. The HFA3861 is housed in a thin plastic quad
flat package (TQFP) suitable for PCMCIA board
applications.
