HFA3824A  
Data Sheet  
August 1998  
File Number 4459.2  
Direct Sequence Spread Spectrum  
Baseband Processor  
Features  
• Complete DSSS 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  
• High Data Rate. . . . . . . . . . . . . . . . . . . . . . .up to 4 MBPS  
• Processing Gain. . . . . . . . . . . . . . . . . . . . . . . . up to 12dB  
• Programmable PN Code . . . . . . . . . . . . . . . .up to 16 Bits  
• Ultra Small Package. . . . . . . . . . . . . . . . . . . . 7 x 7 x 1mm  
• Single Supply Operation (44MHz Max) . . . . . 2.7V to 5.5V  
• Modulation Method. . . . . . . . . . . . . . . .DBPSK or DQPSK  
• Supports Full or Half Duplex Operations  
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  
• On-Chip A/D Converters for I/Q Data (3-Bit, 44 MSPS)  
and RSSI (6-Bit, 2 MSPS)  
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.  
• Backward Compatible with HSP3824  
• Programmable Rotation I, Q Sense  
Applications  
• Systems Targeting IEEE802.11 Standard  
• DSSS PCMCIA Wireless Transceiver  
• Spread Spectrum WLAN RF Modems  
• TDMA Packet Protocol Radios  
• Part 15 Compliant Radio Links  
• Portable Bar Code Scanners/POS Terminal  
• Portable PDA/Notebook Computer  
• Wireless Digital Audio
