单片机编程 PCA9549 Octal bus switch with
The PCA9549 provides eight bits of high speed TTL-compatible bus switching controlledby the I2C-bus. The low ON-state resistance of the switch allows connections to be madewith minimal propagation delay. Any individual A to B channel or combination of channelscan be selected via the I2C-bus, determi ...
单片机编程 1A SIMPLE STEP-DOWN SWITCHING
The TL2575 and TL2575HV represent superior alternatives to popular three-terminal linear regulators. Due totheir high efficiency, the devices significantly reduce the size of the heatsink and, in many cases, no heatsink isrequired. Optimized for use with standard series of inductors available from s ...
通信网络 基于以太网分布式的数据采集控制系统
针对飞行模拟器座舱数据采集的复杂性，设计了一种基于以太网分布式的数据采集控制系统，该系统是RCM5700微处理器模块上的以太网应用。在系统的基础上具体讨论了PoE技术的应用，在传输数据的网线上同时提供电流，提出并实现了一种包括辅助电源在内的完整可靠的PoE供电方案。设计采用美国国家半导体的LM5073和LM5576并根据不 ...

多远程二极管温度传感器-Design Considerations for pc thermal management
Multiple RDTS (remote diode temperature sensing) provides the most accurate method of sensing an IC’s junction temperature. It overcomes thermal gradient and placement issues encountered when trying to place external sensors. PC ...
无线通信 RF Power Amplifiers for Wireless Communications, Second Edition
When I started writing the first edition of RF Power Amplifiers for Wireless Communications,some time back in 1997, it seemed that I was roaming a largely uninhabitedlandscape. For reasons still not clear to me there were few, if any, otherbooks dedicated to the subject of RF power amplifiers. Rig ...
无线通信 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 antenn ...

ARM7硬件说明与开发
The ARM7 is a low-power, general purpose 32-bit RISC microprocessor macrocell for use in application or
customer-specific integrated circuts (ASICs or CSICs). Its simple, elegant and fully static design is
particularly suitable for cost and power-sensitive applications. The ARM7’ ...

This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 &micro m CMOS process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the sync ...
