HFA3860A  
Data Sheet  
November 1998  
File Number 4488.2  
Direct Sequence Spread Spectrum  
Baseband  
Features  
• Complete DSSS Baseband Processor  
™
The Intersil HFA3860A Direct  
Sequence Spread Spectrum (DSSS)  
baseband processor is part of the  
PRISM™ 2.4GHz radio chipset, and  
contains all the functions necessary for  
• Processing Gain. . . . . . . . . . . . . . . . . . . . . . . . . . ≥10.4dB  
• Programmable Data Rate. . . . . . . .1, 2, 5.5, and 11MBPS  
• Ultra Small Package. . . . . . . . . . . . . . . . . . . . 7 x 7 x 1mm  
• Single Supply Operation (44MHz Max) . . . . . 2.7V to 3.6V  
• Modulation Methods. . . . . . .DBPSK, DQPSK, and MBOK  
• Supports Full or Half Duplex Operations  
a full or half duplex packet baseband transceiver.  
The HFA3860A has on-board A/Ds 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 data scrambling capability, are available  
along with M-Ary Bi-Orthogonal Keying to provide a variety  
of data rates. Built-in flexibility allows the HFA3860A to be  
configured through a general purpose control bus, for a  
range of applications. A Receive Signal Strength Indicator  
(RSSI) monitoring function with on-board 6-bit A/D provides  
Clear Channel Assessment (CCA) to avoid data collisions  
and optimize network throughput. The HFA3860A is housed  
in a thin plastic quad flat package (TQFP) suitable for  
PCMCIA board applications.  
• On-Chip A/D Converters for I/Q Data (3-Bit, 22MSPS) and  
RSSI (6-Bit)  
• Backwards Compatible with HFA3860  
• Supports Antenna Diversity  
Applications  
• Enterprise WLAN Systems  
• Systems Targeting Ethernet Data Rates  
• 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
