Abstract: A handful of components are integrated into a circuit that creates a high-quality random data stream that generates eye diagrams up to 62.5MHz. The circuit diagram and eye diagram are shown. The eye diagram, one...

Abstract: This application note describes the use and features of six available DVD formats: DVD-ROM, DVD-R, DVD-RW, DVD-RAM, DVD+R, and DVD+RW. It explains how recording and rewriting work, including the bit stream coding and recording/re...

Abstract: This application note explains how to eliminate the voltage change when a digital potentiometer is used as a voltage-divider in series with other resistors. IntroductionMechanical and electronic digit...

Abstract: This application note presents three designs that use references with digital potentiometers to adjust voltages. As the designs increase in complexity and number of references, the voltage can be adjusted even higher. The MAX5436...

Abstract: This application note analyses the parameters that affect the errors in precision digital-to-analog converter (DAC) applications. The analysis focuses on the factors introduced by both the data converter and the voltage reference...

Abstract: Design idea outlining how to use an I2C-controlled analog switch to triple the number of devices connected to an I2C bus. Perhaps the most effective way to gain board space and increase component density is to m...

Abstract: This note discusses the effects on switches when used to connect loads. High currents through a switch degrade its quality when used as a power switch. Both mechanical switches and relays exhibit switch bounce during operation. T...

射頻識別（RFID）技術(shù)近年來在國內(nèi)外得到了迅速發(fā)展。對于需要電池供電的便攜式系統(tǒng)，功耗也越來越受到人們的重視。本文將具體闡述基于MSP430F2012和CC1100低功耗設(shè)計理念的雙向...

Abstract: Many servers need to be able to switch video, keyboard, mouse, and perhaps audio signals from one of several computers to a front panel. This application note focuses on the keyboard/mouse portion, and presents a circuit for impl...

Abstract: This application note describes the hardware and software differences between the Dallas Semiconductor DS21Q44 and the DS21Q43A quad port framer devices. The DS21Q44 quad E1 framer, offers a broader feature set while retaining th...

Abstract: Some special functions are not derivable by using the normal transmit and receive side registers. In order to derive those functions, we need to use the test registers of the following devices: DS21Q42, DS21Q44, DS2152, DS2154, D...

Abstract: This application note describes the hardware and software differences between the Dallas Semiconductor DS21Q42 and the DS21Q41B quad port framer devices. The DS21Q42 enhanced quad T1 framer offers a broader feature set while reta...

Abstract: This application note show how to connect the DS21x5y family of single chip transceivers (SCTs) to the Texas Instruments TSM320C54x family of digital signal processors (DSPs) utilizing the buffered serial port. Both continuous an...

Abstract: Tech Brief 7 provides the requirements for multiplexing four PCM streams into one 8MHz system backplane using the Dallas Semiconductor/Maxim DS2152 and DS2154 T1/E1 single chip tranceivers (SCTs). The DS2155, DS26528, DS26524, DS...

Abstract: The application note describes how to design a backplane of 8.192MHz that simultaneously connects to any four framers of the following: DS21Q41 quad T1 framer, DS21Q43 E1 framer, DS2141 T1 controller, DS2151 T1 single chip transc...
