Small PRISM 2.5 reference design with USB interface

1 August 2001 Telecoms, Datacoms, Wireless, IoT

Intersil has released what it claims is the industry's smallest wireless reference design. It provides all the integrated circuits, software, firmware and a companion voltage-controlled oscillator to give systems manufacturers a highly integrated, and complete solution for designing 802.11b-compliant wireless networking capability into small, handheld devices according to the company.

Featuring a universal serial bus (USB 1.1) interface and based on Intersil's PRISM 2.5 chipset, the reference design speeds the development of smaller wireless enabled products that provide access to networks and the Internet for fast, efficient transmission of data, video and VoIP services.

The ISL37300U reference design allows a complete WLAN adapter to be provided on a small mini-USB card measuring approximately 60 x 38 mm - ideal for small form factor applications including embedded and external USB-based applications. The PRISM 2.5 chipset's integrated ISL3873 BBP/MAC simplifies the design to add embedded wireless LAN capability to products that connect with USB to the host device. The solution delivers full 11 Mbps data rates and fully complies with the IEEE-802.11b standard, allowing manufactures to achieve Wi-Fi certification.
