全科科技创立于1991年4月，为专业通讯组件设计及通路商，网罗国际知名通讯大厂之研发专才，以整体性的规划，突破一般零组件代理商仅能提供价格和交期之限制，将各项通讯IC及解决方案引进客户端，协助客户解决产品开发瓶颈，全面提升产业水准。
Broadcom 的 AirForce™ 产品系列提供系统设计行业最广泛的 Wi-Fi® 集成电路, 应用范围从 PC 和消费类设备到接入点和路由器.Broadcom 的 AirForce™ 802.11a, 802.11b, 54g® 和 Intensi-fi® 解决方案使制造商能够生产具有消费者和企业所需的性能, 互操作性, 安全性和易用性的 Wi-Fi 产品.领先的 Wi-Fi 产品品牌, 如 Apple, Belkin, Buffalo, Dell, eMachines, Gateway, HP, Linksys/Cisco 和 Motorola, 都采用了 AirForce 解决方案.
所有 AirForce 芯片集都具有全 CMOS 设计, SmartRadio™ 性能以及使大批量无线局域网产品的设计和制造更容易的通用体系结构.这种高度集成的体系结构使 Broadcom 能够提供业界第一个单片 Wi-Fi 解决方案.另外, Broadcom 的 OneDriver™ 软件适用于所有 802.11a, 802.11b, 802.11g 和 draft-802.11n 解决方案, 从而提供单个驱动程序映像和许多基于标准的性能增强功能, 包括 Xpress™ Technology 和 125 High Speed Mode™(获得更大的总体网络吞吐量), BroadRange™(在更长的传输距离内获得更高的性能)和 SecureEasySetup™(用于按钮设置和安全性配置).
AirForce 系列还具有业界最高的安全性, 因为它采用 Wi-Fi Protected Access™(WPA 和 WPA2)这种基于硬件的高级加密标准 (AES) 实现方法并支持 Cisco Compatible Extensions (CCX4).
BCM4325 - Low-Power 802.11a/b/g with Bluetooth® 2.1 + EDR and FM
Low-Power 802.11a/b/g with Bluetooth® 2.1 + EDR and FM
The Broadcom BCM4325 family of single-chip devices provides for the highest level of integration for a mobile or handheld wireless system, with integrated IEEE 802.11a/b/g (MAC/Baseband/Radio), Bluetooth 2.1 + enhanced data rate (EDR), and FM receiver. Thus providing a compact small form factor solution with minimal external components to drive the costs for mass volumes and allows for flexibility in size, form, and function of handheld devices. The BCM4325 is designed to address the needs of highly mobile devices that require minimal power consumption and reliable operation.
The BCM4325 utilizes advanced design techniques and process technology to deliver the lowest active and idle power, extending the system battery life while maintaining consistent connectivity, and still provides a rich set of features.
BCM4751 - Integrated Monolithic GPS Receiver
Integrated Monolithic GPS Receiver
Provides Faster Signal Searches, Accurate Real-Time Navigation, Improved Tracking Sensitivity and Very Low Average Power Consumption
The Broadcom BCM4751 is a single-chip GPS receiver used for tracking and navigation, primarily in mobile devices. Its massively parallel, hardware correlator architecture provides faster signal searches, accurate real-time navigation, improved tracking sensitivity and very low average power consumption.
The BCM4751 integrates a number of external components that reduce the overall system cost for manufacturers and enables very small footprints when designing GPS into mobile devices. With real estate in mobile devices at a premium, a complete GPS solution, featuring the BCM4751, will use less than 30 mm² of board space, including all of the necessary components for a typical cellular phone implementation. |
