C Detects transmission rate of RS-232 interface -  09/30/99 EDN-Design Ideas RS-232 is the most common serial interface in the PC world.  Most RS-232 interfaces communicate with the receiver at a fixed transmission rate, such as 9600 baud.  But what happens if the transmitter operates with different transmission rates? Different transmission rates__ Circuit Design by Thomas Schmidt, Microchip Technology, Chandler, AZ

ADC's Reference Improves RTD Measurements -  10/27/94 EDN-Design Ideas Temperature measurements using RTDs   (resistance-temperature detectors]generally employ bridge circuits with stable power supplies for signal conditioning.  Unfortunately, this scheme generally produces nonlinear outputs.  A linear b__ Circuit Design by Bharat Heavy Electricals Ltd, Tiruchirapalli, India

Advantages of AC-Coupling in SerDes Applications -  This App Note presents several benefits of using capacitors to AC-couple an LVDS data link.  The article guides the reader through proper capacitor selection and termination topology.  Common troubleshooting issues are discussedApp Note 4085-- 3/04/2008 --   (add 5/08) __ Maxim Integrated

Design a Low Jitter Clock for High Speed Data Converters -  App Note/ 800 / Aug-05___ Maxim Integrated

Design a Visible Optical Link for RS-232C Communications -  01/09/03 EDN-Design Ideas Embedded processor directly drives LCDThe design in Figure 1 is a visible optical link for those who need to see the transmitted data.  An isolation figure ofthan 5000V is a bonus.  Tests of the system used the COM input of a data-acquisition system, as well as a standard PC's COM port.  The MC1489 converts the RS-232C data to TTL signals__ Circuit Design by Shyam Tiwari, Sensors Technology Ltd, Gwalior, India

Dual PICAXE Infared Data Communication -  What's this? Twin Picaxes? Is this Stan's idea of an April Fools Day Joke? Maybe he's just seeing double ___ SiliconChip

Dual-voltage regulator meets USB-power needs -  19-Aug-04 EDN-Design Ideas This design idea stems from the limited availability of IC voltage regulators that can meet key USB-power specs, coupled with the need for turn-on sequencing and rise-time control at each output.  As always, for PC-related designs, minimum cost is a primary motivation.  USB specs require all loads to limit inrush current to less than 100 mA plus 50 C of charge when powered on__ Circuit Design by Wayne Rewinkel, National Semiconductor, Phoenix, AZ

Effects of Digital Crosstalk in Data Converters -  App Note/ 1761 / May-06___ Maxim Integrated

Efficient All-In-One USB Power Management IC Solution -  DN1008 Design Notes___ Linear Technology/Analog Devices

Ethernet 10BaseT simulator jig yields zero emissions -  10/22/98 EDN-Design Ideas (File has several circuits, scroll to find this one)  A test jig (Figure 1) is a valuable tool because it evaluates RF emissions from Ethernet unshielded-twisted-pair (UTP) 10BaseT LAN-interface devices without contaminating the measured results with its own RF emissions.  When an RF-emissions-measurement lab tests a multiport, UTP 10BaseT Ethernet device for compliance with FCC-radiated emission limits, the test is meaningful only if the device transmits data packets from all 10BaseT ports.  __ Circuit Design by Glen Chenier, Fujitsu Network Communications, Richardson, TX

Extending the Applications of 5V Powered RS-232 Transceivers -  DN14 Design Notes___ Linear Technology/Analog Devices

Get Power Out of PC Parallel Port -  An article which includes circuits, shares how to us a parallel port to connect to a very wide selection of devices like software protection dongles, removable disks, modems, network adapters, printer sharing units, parallel port extenders, soundcards, electronic telecard readers and many circuits.   __ Designed by Tomi Engdahl

Humidty Sensor to Data Aquisition System Interface -  The circuit shown in the schematic features zero drift operational amplifiers (LTC1250 and LTC1050) and a precision instrumentation switched capacitor block (LTC1043).  This design will maintain excellent DC accuracy down to microvolt levels.  This method was chosen over the use of a true RMS-to-DC or log converter because of __ Linear Technology/Analog Devices App Note, Mar 16th 2011

Interface a Serial 12-Bit ADC to a PC -  10-Jul-03 EDN-Design Ideas Over the years, IC manufacturers have devised various ways of effecting interfaces and paying special attention to reducing the number of ICs' interface-I/O pins.  The MAX187 is one such device, a 12-bit A/D converter.  You can create an interface to this ADC using serial data- communications techniques__ Circuit Design by DS Oberoi and Harinder Dhingra, GCET, Jammu, India

Isolated RS232 for PIC16F84 -  Connect serial transmit bit of the transformerless supply PIC16F84 circuit with COM1 through the use of isolation device.  Protect your notebook from direct connected to power line.   __ Designed by Wichit Sirichote

Low-Cost RS-232C Multiplexer Serves as Multiport Adapter -  03/01/96 EDN-Design Ideas Multiport RS-232C PC add-on boards are intended for intensive multichannel communication.  Therefore, each serial port has its own transmission controller.  If your application doesn't need interrupt-driven service, and polling the devices through RS-232C channels one after another is sufficient, then you can use a single controller with switched input and output signals instead of installing a costly multiport adapter.__ Circuit Design by Jerzy R Chrzaszcz, Institute of Computer Science, Warsaw University of Technology  Warsaw, Poland

LTC1387: 5V RS-232/RS485 Multiprotocol Transceiver -  DN176 Design Notes___ Linear Technology/Analog Devices

LVDT Signal Conditioning -  An LVDT transformer is exited with a fixed frequency sine wave.  The distance of displacement of the movable core will change the amplitude of the transformer output which is is converted to a dc voltage by the LT1967 True RMS converter.  The direction of the core movement is indicated by the phase shift of the sine wave and is detected by a simple phase comparator circuit.  __ Linear Technology/Analog Devices App Note, Mar 16, 2010

Multiply Your Sampling Rate with Time Interleaved Data Converters -  App Note/ 384 / Sep-07) __ Maxim Integrated

PC Monitors two-way RS-232 transmission -  02/01/01 EDN-Design Ideas The goal of monitoring transmission in a data link is obvious: You want to know the contents of the data, when it was sent, and by whom.  If one of the communicating parties is a PC or another user-programmable controller, then you can modify parameter settings or, at worst, change transmission routines to generate log files or perform other actions.  __ Circuit Design by Jerzy Chrzaszcz, Warsaw University of Technology, Poland
