  • Create a 1-Wire Master with Xilinx PicoBlaze

    Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wire slave devices. The systemimplements a 1-Wire master connected to a UART and outputs temperature to a PC from the DS28EA00 temperaturesensor. In addition, high/low alarm outputs are displayed from the DS28EA00 PIO pins using LEDs.

  • Employing a Single-Chip Transceiver in Femtocell Base-Station Applications

    Abstract: This application note discusses the development and deployment of 3G cellular femtocell base stations. The technicalchallenges for last-mile residential connectivity and adding system capacity in dense urban environments are discussed, with 3Gfemtocell base stations as a cost-effective solution. Maxim's 3GPP TS25.104-compliant transceiver solution is presented along withcomplete radio reference designs such as RD2550. For more information on the RD2550, see reference design 5364, "FemtocellRadio Reference Designs Using the MAX2550–MAX2553 Transceivers."
