Application Scenarios & Design Considerations

Wireless LAN Integrated Medium Access Controller with Baseband Processor

Alternative Part Number

  • MAX2820ETI+ --: 2.4 GHz 802.11b transceiver in a similar function class, offered by a different vendor as a drop-in style alternative for wireless LAN designs.
  • LMX5252TMX --: Integrated 2.4 GHz WLAN radio transceiver comparable to the ISL3873 function, from a different series and manufacturer.
  • SA2400A --: 2.4 GHz 802.11b transceiver IC serving the same wireless LAN application, with a clearly different part naming and vendor.
  • PRISM2.5 --: The ISL3873 is a PRISM 2.5 WLAN baseband/MAC chipset device; the PRISM2.5 chipset family is the direct functional equivalent for wireless LAN applications.
  • HFA3863 --: Intersil/Harris PRISM-series baseband processor with similar 2.4 GHz WLAN modem functionality, suitable as a functional substitute in PRISM-based designs.
  • ISL3886 --: Later Intersil PRISM-family WLAN baseband/MAC controller offering comparable interface and functionality, usable as an upgrade path for the ISL3873.
