HDQ Communication Basics (Rev. A)
Texas InstrumentsThis report compares the communication timing specifications for the different battery gas gauge and battery monitor products. It discusses some of the interface requirements necessary for robust HDQ communication such as the need for a break prior to each communication how to reliably read 16-bit dynamic values over the 8-bit bus and the need for some noise filtering on the HDQ line. It also
Random Number Generation on a TMS320C5x
Texas InstrumentsThis document discusses how a random number can be generated on a TMS320C5x. The goal of this application note is to provide a fast proven useful random number generator that can be used in various fixed-point applications. The theory is discussed and a code example is provided.
Macromodels for RF Op Amps Are a Powerful Design Tool
Texas InstrumentsThe macromodel for the Diamond Transistor OPA660 gives an example of the structure and performance of these new Spice models.
Vocoder Implementation Using TMS470 High-End Timer
Texas InstrumentsThe TMS470 family of ARM7 microcontrollers contains a RISC coprocessor referred to as the High-End Timer (HET). The HET can implement complex I/O operations independent from the CPU one of which is the capability to generate PWM signals. This application report describes using this PWM capability along with an open source voice algorithm called Speex to encode 8-bit voice messages without the n
4-Wire and 8-Wire Resistive Touch-Screen Controller Using the MSP430 (Rev. A)
Texas InstrumentsThis application report describes how to use an MSP4309(tm) microcontroller to drive and read a resistive touch screen. The hardware and software solutions provided enable the reading of user input th
Clock jitter analyzed in the time domain, Part 3
Texas InstrumentsPart 1 of this three-part article series focused on how to accurately estimate jitter from a clock source and combine it with the aperture jitter of an ADC. In Part 2, that combined jitter was used to calculate the ADC’s signal-to-noise ratio (SNR), which was then compared against actual measurements. This article, Part 3, shows how to further increase the SNR of the ADC by improving the ADC’s aperture jitter, with a focus on optimizing the slew rate of the clock signal.

Application and Design Considerations for CDC5xx Phase-Lock Loop Clock Drivers
Texas InstrumentsToday?s high-speed system designs require stringent propagation and skew parameters to maintain desired system performance. TI developed the CDC5XX platform of PLL clock drivers to meet the need for high-performance clock system components. This document describes the features and functions of the CDC5XX and discusses design considerations and configurations for the CDC586 CDC582 and CDC2582 clo
Bit-Reversed Addressing in C on the C3x
Texas InstrumentsThe C compiler does not support bit-reversed addressing. This document contains a code example showing how to embed assembly language statements into the C code to do this.
Using the ADSDeSer-50EVM to Deserialize ADS527x 10-Bit Outputs
Texas InstrumentsThe ADSDeSer-50EVM provides an direct means of examining the serialized 10-bit data output from the ADS527x families of serialized low voltage differential signal(LVDS) data converters by deserializing the data and converting to a parallel data port. This application report discusses the process of reading deserialized 10-bit data outputs from the ADS527x family using the ADSDeSer50-EVM.
