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 ADCs 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 exibility allows the HFA3824A to be congured 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 at package (TQFP) suitable for PCMCIA board applications By Intersil Corporation
