Building a QAM Modulator
Texas InstrumentsThis report describes how one can use the GC2011 Digital Filter chip to build digital modulators for most BPSK QPSK and QAM radio signals. The modulator described here will accept a data stream with a symbol rate equal to B (standing for baud) and will output a modulated QAM signal centered at an IF frequency equal to the symbol rate or twice the symbol rate (B or 2B). A typical application woul
Load Dump and Cranking Protection for Automotive Backlight LED Power Supply (Rev. A)
Texas InstrumentsAutomotive electronic systems can be subjected to wide input voltage variations resulting from cold cranking and load dump conditions. The need for over voltage protection is particularly common in automotive 12 V and 24 V systems where peak load dump transients can be as high as 60 V. Cranking condition sags the battery voltage to a low value when the battery is supplying current to an electric s

Texas InstrumentsThis application report contains frequently asked questions (FAQs).
Using the USB APLL on the TMS320VC5506/C5507/C5509A (Rev. B)
Texas InstrumentsThis document describes how to switch to and program the unisersal serial bus (USB) analog phase-locked loop (APLL) on the C5506/C5507/C5509A devices. Example assembly programs for programming and switching to and from the APLL are also provided in the attached zip file. It is assumed that the reader is familiar with the use and operation of the C5506/C5507/C5509A USB digital phase-locked loop (DP
Low-Cost Noise-Immune Isolated Thermocouple Signal Processor
Texas InstrumentsThis application report describes a low-cost thermocouple-based temperature measurement system featuring high-noise immunity and electrical isolation between the analog and digital circuits. Unlike conventional designs employing analog cold junction compensation in this design the thermocouple is connected directly to the differential inputs of an INA326 instrumentation amplifier. This configur

Interfacing High-Speed LVDS Outputs of the ADS527x/ADS524x
Texas InstrumentsThe ADS527x and ADS524x families of devices are high-performance octal/quad channel analog-to-digital converters ideal for the highest system density. Serial low voltage differential signaling (LVDS) outputs reduce the number of I/O interfaces required power and overall package size. These device families are rated to work from sampling rates of 20MSPS to 70MSPS corresponding to data rates of 2
Data Capture with Multiple ADS1244 or ADS1245 Devices in Parallel
Texas InstrumentsThe ADS1244 and ADS1245 are excellent low-power high-precision analog-to-digital converters (ADCs). This application note discusses several important considerations when using the ADS1244/45 devices in multi-channel parallel measurement systems.
XgxPerf Toolkit
Texas InstrumentsThis application report shows how to use the XgxPerf toolkit to build and benchmark a Qt™ based application. It is assumed that you are familiar with installing and writing applications based on Qt.
Network Developer's Kit (NDK) Benchmarks (Rev. A)
Texas InstrumentsThis document describes a procedure to benchmark the Network Developer?s Kit (NDK) using Code Composer Studio™ software and some additional command-line tools. Source code is provided in a compa
The Impact of DWARF on TI Object Files
Texas InstrumentsThis document identifies the differences in object file content when DWARF replaces COFF as the primary debug information format. Please refer to DWARF Debugging Information Format Specification Version 2.0 for a description of this format.
High Resolution Video Using the DM642 DSP and the THS8200 Driver (Rev. A)
Texas InstrumentsThe DM642 DSP has three 20-bit video ports capable of high definition (HD) display. The video ports can be programmed to follow HDTV standards such as SMPTE274M and SMPTE296M. These HDTV standards follow a 4:2:2 convention where luminance and chrominance signals are separated onto two different 8- or 10-bit data paths. This convention is more commonly called Y/C mode. Many new HD displays accept
High-Performance Backplane Design With GTL+ (Rev. A)
Texas InstrumentsResults from a system that demonstrates the performance of GTL+ devices in a backplane are provided. The Texas Instruments (TI) GTL16622A is the example used in the design of the physical backplane. The TI backplane demonstration system is a useful tool for designers in understanding issues related to loading effects termination signal integrity and data-transfer rate in a high-performance
The TPS71501 External PNP Transistor Boosts LDO Output Current
Texas InstrumentsUsing an external PNP transistor together with a low-dropout (LDO) regulator such as the TPS71501 supplies a load current of 1 A with an output of 9 V.
