The NCV7356 is a physical layer deviCE for a single wire data linkcapable of operating with various Carrier Sense Multiple Accesswith Collision Resolution (CSMA/CR) protocols such as the BoschController Area Network (CAN) version 2.0. This serial data linknetwork is intended for use in applications where high data rate is notrequired and a lower data rate can achieve cost reductions in both thephysical media components and in the microprocessor and/ordedicated logic deviCEs which use the network.The network shall be able to operate in either the normal data ratemode or a high-speed data download mode for assembly line andservice data transfer operations. The high-speed mode is onlyintended to be operational when the bus is attached to an off-boardservice node. This node shall provide temporary bus electrical loadswhich facilitate higher speed operation. Such temporary loads shouldbe removed when not performing download operations.The bit rate for normal communications is typically 33 kbit/s, forhigh-speed transmissions like described above a typical bit rate of83 kbit/s is recommended. The NCV7356 features undervoltagelockout, timeout for faulty blocked input signals, output blankingtime in case of bus ringing and a very low sleep mode current.

The CC1101 is a low-cost sub- 1 GHztransceiver designed for very low-powerwireless applications. The circuit is mainlyintended for the ISM (Industrial, Scientific andMedical) and SRD (Short Range deviCE)frequency bands at 315, 433, 868, and 915MHz, but can easily be programmed foroperation at other frequencies in the 300-348MHz, 387-464 MHz and 779-928 MHz bands.CC1101 is an improved and code compatibleversion of the CC1100 RF transceiver. Themain improvements on the CC1101 include:

Abstract: When people want portable music, they usually rely on battery-powered audio deviCEs. With a bit of engineeringblood (or curiosity) running in your veins, it is not difficult to build a wireless Bluetooth® stereo audio system that can becontrolled with any deviCE that has a Bluetooth connection and a music player

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.

Abstract: This application note helps system designers choose the correct external components for use with the MAX16948 dualremote antenna LDO/switch, thus ensuring that automobile-regulated phantom antenna supply and output-current-monitoring circuitrymeet performance objectives. An electronic calculator is provided that helps specify the critical external components for theMAX16948, thus reducing design time. The calculator also determines the deviCE's analog output voltage, output current-limitthreshold, and output current-sensing accuracies. The calculator includes new automatic Step By Step feature that assists designerswith component choice. To use the new automatic feature, click on the Step By Step button relative to the desired section.

The LTC®3207/LTC3207-1 is a 600mA LED/Camera driverwhich illuminates 12 Universal LEDs (ULEDs) and onecamera fl ash LED. The ULEDs are considered universalbecause they may be individually turned on or off, setin general purpose output (GPO) mode, set to blink at aselected on-time and period, or gradate on and off at aselected gradation rate. This deviCE also has an externalenable (ENU) pin that may be used to blink, gradate, orturn on/off the LEDs without using the I2C bus. This may beuseful if the microprocessor is in sleep or standby mode. Ifused properly, these features may save valuable memoryspace, programming time, and reduce the I2C traffi c.

It would not be an exaggeration to say that semiconductor deviCEs have transformed humanlife. From computers to communications to internet and video games these deviCEs and the technologies they have enabled have expanded human experience in a way that is unique in history. Semiconductor deviCEs have exploited materials, physics and imaginative applications to spawn new lifestyles. Of course for the deviCE engineer, in spite of the advances, the challenges of reaching higher frequency, lower power consumption, higher power generation etc.

1. 简介 ISIS中的属性有非常大的用处。一个特定的对象的属性是由一些关键字组成，比如，在ISIS中，我们使用封装的属性与PCB的封装关联。 对象，管脚，电路图都有自己的属性，如果你想很把这个功能强大的软件用好你必须很清楚他们之间的联系，这个软件和以前你所用过的画电路的软件有些不同。 2. 对象属性 对象属性有两个类型—系统属性和使用属性。在ISIS中的这些功能是由一些保留字所组成，不管是内部的程序比如ARES和VSM，或者你自己所使用的软件都是有关联的。 (1)系统属性 系统属性在ISIS中是由一些特殊含义的关键字所够成。比如，一个元件中的deviCE属性是根据元件库在分配时候定义的。这些属性一般是文本的—比如元件的REF和VALUE属性可以直接从Edit Component对话框中访问，但是别的比如deviCE属性就是做为图形操作所生成的结果。

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.

Introduction to Xilinx Packaging Electronic packages are interconnectable housings for semiconductor deviCEs. The major functions of the electronic packages are to provide electrical interconnections between the IC and the board and to efficiently remove heat generated by the deviCE. Feature sizes are constantly shrinking, resulting in increased number of transistors being packed into the deviCE. Today's submicron technology is also enabling large-scale functional integration and system-on-a-chip solutions. In order to keep pace with these new advancements in silicon technologies, semiconductor packages have also evolved to provide improved deviCE functionality and performance. Feature size at the deviCE level is driving package feature sizes down to the design rules of the early transistors. To meet these demands, electronic packages must be flexible to address high pin counts, reduced pitch and form factor requirements. At the same time,packages must be reliable and cost effective.
