| Intensi-fiTM (R) DRAFT-802.11n PRODUCT FAMILY FEATURES (R) * First IEEE 802.11n draft-compliant Wi-Fi solution * BCM4321--MAC/baseband controller for draft-802.11n and (R) SYSTEM/CHIP BENEFITS * Reference Designs * * * * * 802.11a/b/g devices (PCI/PCI Express /CardBus) BCM2055--2x2 dual-band single-chip radio--3x3 and 4x4 antenna options for increased range and performance All CMOS implementation of the world's most advanced system architecture for draft-802.11n networks Fully backward-compatible with IEEE 802.11a/b/g legacy devices Allows cost-effective system design using low-cost PCB and single-sided assembly High-performance features across the Intensi-fiTM product line * High-performance whole house wireless coverage * OneDriverTM * SecureEasySetupTM * SmartRadioTM * WPATM/WPA2TM * Cisco(R) Compatible Extensions (CCX4) * Full-rate Advanced Encryption Standard (AES) engine in hardware * WMMTM for quality of service * * * * * * * * * BCM94321CB2--CardBus reference design * BCM94321MP--Mini PCI reference design * BCM94321MC--PCI Express Mini Card reference design * BCM94704NR--AP/Router reference design * BCM94705NR--GbE AP/Router reference design Two spatially multiplexed streams support data rates up to 270 Mbps. Increased rate/range performance enhances user satisfaction while reducing product support calls. Self-calibrating architecture allows high-yield board manufacturing. 2x2 antenna structure maintains form factor compatibility with high-volume IEEE 802.11a/g industrial designs. Low-cost CMOS implementation for MAC, baseband, and radio allows integration with Broadcom's cable/DSL/set-top/ VoIP chipsets. OneDriver: Single driver across platforms simplifies driver update process and improves customer satisfaction. Designs meet Pb-free/RoHS worldwide requirements. SecureEasySetup for simple Wi-Fi setup and security configuration. APPLICATIONS * Wireless client cards for desktop and notebook PCs (PCI, PCI Express, Mini Card, Mini PCI, and CardBus form factors) * High-performance draft-802.11n router solutions with the BCM4704 SoC and BCM4705 SoC * Home multimedia entertainment wireless networks * Consumer Wi-Fi devices and other embedded applications requiring high-performance throughput and range Intensi-fi Reference Designs OVERVIEW BCM4321 and BCM2055 AP/Router Block Diagram Flash Memory EBI Host UART USB 1.1 Host or Device x1 Modem/ Audio/ GPIO JTAG 2.5V Reg 1.8V Reg PCI Express Internal Bus Intensi-fi Draft - 802.11n MAC Intensi-fi Draft - 802.11n PHY/AFE 264 - 300 MHz MIPS32 Core with MMU PCI 2.3 Host PCI V2.3 BCM2055 RF Radio DDR/SDR SDRAM SDRAM I/F USB 1.1 Host Security 10/100 MAC 10/100 MAC LED GPIO BCM4704 AP/Router SPROM I/F 4 Kb OTP BCM4321 CardBus/Mini PCI/PCI Express BCM5325E/F Magnetics 10/100 WAN RJ-45 Quad Magnetics 10/100 LAN RJ-45 Intensi-fi Specifications Interface/System bus support Standard Data rate (Mbps) PCI/CardBus/PCI Express IEEE 802.11g, 802.11b, 802.11a, Intensi-fi draft-802.11n 54, 48, 36, 24, 18, 12, 9, 6, 11, 5.5, 2, 1 20 MHz BW: 130, 117, 104, 78, 52, 39, 26, 13 40 MHz BW: 270, 243, 216, 162, 108, 81, 54, 27 PSK/CCK, DQPSK, DBPSK, OFDM Infrastructure and ad hoc 2.4 GHz--2.5 GHz, 4.9 GHz--5.85 GHz 2.4 GHz: 11 for North America, 13 for Europe, and 14 for Japan 5 GHz: 12 for North America, 19 for Europe, and 4 for Japan 2x2: 2.4 GHz 16 dBm 1.5 dB, 5 GHz 14.5 dBm 1.5 dB Two or more antennas for simultaneous transmission and reception 1.8V (3.3V for reference designs) Average standby <130 mW IEEE 802.1x, WEP/WEP2, WPA/WPA2, TKIP, Weak-key avoidance, CCX, CCX 2.0, CCX 3.0, CCX4.0, 128-bit OCB mode AES, IEEE 802.11i Microsoft(R) Vista, Windows(R) XP, Windows(R) 2000, Linux(R), VxWorks(R) Worldwide regulatory, Wi-Fi 802.11a/b/g, WHQL, CCX Modulation Network architectures Operating frequencies Operating channels RF output power Antenna connectors Power requirements Power consumption Security Software support Certifications ORDERING INFORMATION BCM94321CB2 BCM94321MP BCM94321MC BCM94704NR BCM94705NR 2.4-GHz Intensi-fi draft-802.11n CardBus reference design 2.4/5-GHz Intensi-fi draft-802.11n Mini PCI reference design 2.4/5-GHz Intensi-fi draft-802.11n PCI Express Mini Card reference design 2.4/5-GHz Intensi-fi draft-802.11n AP/Router reference design 2.4/5-GHz Intensi-fi draft-802.11n GbE AP/Router reference design Broadcom(R), the pulse logo, Connecting everything(R), the Connecting everything logo, Intensi-fiTM, SecureEasySetupTM, SmartRadioTM, and OneDriverTM are among the trademarks of Broadcom Corporation and/or its affiliates in the United States, certain other countries and/or the EU.
