NOTE

  • 带有SerDes接口的PLB千兆位级以太网MAC

    This application NOTE describes a reference system which illustrates how to build an embeddedPowerPC® system using the Xilinx 1-Gigabit Ethernet Media Access Controller processor core.This system has the PLB_Gemac configured to use Scatter/Gather Direct Memory Access andthe Serializer/Deserializer (SerDes) interface. This application NOTE describes how to set up thespecific clocking structure required for the SerDes interface and the constraints to be added tothe UCF file. This reference system is complete with a standalone software application to testsome of the main features of this core, including access to registers, DMA capabilities, transmitand receive in loopback mode. This reference system is targeted for the ML300 evaluationboard.

  • XAPP1042-利用GPIO实现以太网PHY寄存器访问

    The XPS Ethernetlite peripheral does not provide any mechanism to access the Ethernet PHYregisters. These registers are used to configure auto negotiation parameters and to obtain PHYstatus. This application NOTE provides reference systems and associated software to accessPHY registers by connecting the serial management bus signals MDC and MDIO to GPIOswhich the software controls directly.

  • 数字卫星设备控制兼容的天线供电系统设计

    Abstract: This application NOTE discusses a design for a phantom antenna power-supply system compatible with theDigital Satellite Equipment Control (DiSEqC) communication standard, using the MAX16948 automotive dual, highvoltageLDO/switch. The presented application circuit provides a remote antenna power supply and also enables onewaycommunication from the radio head unit to the remote antenna. This system architecture offers flexibility inDiSEqC tone-burst frequency choice (100Hz to 30kHz), enabling users the ability to select the best frequency for theirapplication.

  • MAX7060的ASK_FSK的ISM射频发射机

    Abstract: This application NOTE illustrates the flexibility of the MAX7060 ASK/FSK transmitter. While the currently available evaluationkit (EV kit) has been optimized for the device's use in a specific frequency band (i.e., 288MHz to 390MHz), this document addresseshow the EV kit circuitry can be modified for improved operation at 433.92MHz, a frequency commonly used in Europe. Twoalternative match and filter configurations are presented: one for optimizing drain efficiency, the other for achieving higher transmitpower. Features and capabilities of earlier Maxim industrial, scientific, and medical radio-frequency (ISM-RF) transmitters areprovided, allowing comparison of the MAX7060 to its predecessors. Several design guidelines and cautions for using the MAX7060are discussed.
