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.

基本的编辑工具(GENERAL EDITING FACILITIES) 对象放置(Object Placement) ISIS支持多种类型的对象，每一类型对象的具体作用和功能将在下一章给出。虽然类型不同，但放置对象的基本步骤都是一样的。 放置对象的步骤如下(To place an object:) 1.根据对象的类别在工具箱选择相应模式的图标(mode icon)。 2. Select the sub-mode icon for the specific type of object. 2、根据对象的具体类型选择子模式图标(sub-mode icon)。 3、如果对象类型是元件、端点、管脚、图形、符号或标记，从选择器里(selector)选择你想要的对象的名字。对于元件、端点、管脚和符号，可能首先需要从库中调出。 4、如果对象是有方向的，将会在预览窗口显示出来，你可以通过点击旋转和镜象图标来调整对象的朝向。 5、最后，指向编辑窗口并点击鼠标左键放置对象。对于不同的对象，确切的步骤可能略有不同，但你会发现和其它的图形编辑软件是类似的，而且很直观。 选中对象(Tagging an Object) 用鼠标指向对象并点击右键可以选中该对象。该操作选中对象并使其高亮显示，然后可以进行编辑。

This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized safety controllers and provides a significant competitive advantage over traditional microcontroller or ASIC-based designs. Introduction The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas around machines such as fast-moving robots, and distributed control systems in process automation equipment such as those used in petrochemical plants. The International Electrotechnical Commission’s standard, IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was developed in the mid-1980s and has been revised several times to cover the technical advances in various industries. In addition, derivative standards have been developed for specific markets and applications that prescribe the particular requirements on functional safety systems in these industry applications. Example applications include process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC 62304), automotive (ISO 26262), power generation, distribution, and transportation. 图Figure 1.

Today’s digital systems combine a myriad of chips with different voltage configurations.Designers must interface 2.5V processors with 3.3V memories—both RAM and ROM—as wellas 5V buses and multiple peripheral chips. Each chip has specific power supply needs. CPLDsare ideal for handling the multi-voltage interfacing, but do require forethought to ensure correctoperation.
