Not all low dropout (LDO) linear regulator data sheets provide the voltage dropout information needed for all applications. This application report shows a designer how to use an LDO data sheet's specified dropout performance to determine the dropout voltage at other operating conditions.
The purpose of this application report is to facilitate the migration of MSP430F167/F168/F169/F1610/F1611/F1612-based designs to the MSP430F261x device family. In the course of this application report
This document provides a vocabulary of French speech data coded in LPC (format D6). This ready-to-use vocabulary is used to generate a vocal output for Date and Time Stamping (DTS) and voice prompts.
The AFEDRI8201 analog front end chip is an IF analog-to-digital converter for AM/FM/HD/DAB/digital radio systems. This article explains how the AFEDRI8201 can support applications such as HD radio™ Eureka DAB and ISDB-TSB. In addition an actual AFEDRI8201 register configuration example is described.
The TMS320TCI6484 has 32KB L1D SRAM 32KB L1P SRAM and 2MB L2 SRAM. A 32-bit 667MHz DDR2 SDRAM interface is provided on the DSP to support up to 512MB of external memory.
Memory access performance is very critical for software running on the DSP. On the TCI6484 DSP all the memories can be accessed by DSP cores and multiple DMA masters.
The DSP core is capable of performing up to 128 bits
Many applications require multiple analog-to-digital converters (ADC) in a system. Daisy chaining multiple ADCs enables the use of a single data receiver or a small FPGA. It offers easy and minimal digital routing. This application report describes how multiple ADCs (ADS8410/13) work in a daisy-chain mode. The device offers a high-speed (200 Mbps) LVDS serial interface. This application report als
This application report summarizes key information required for understanding the 'LVT8986 linking addressable scan ports (LASPs) multidrop addressable IEEE Std 1149.1 (JTAG) test access port (TAP) tr
This application report presents the new features available in Code Composer Studio?(CCS) v2 that facilitate efficient project management. The CCS Project Management system has been broadened and improved to include: multi-project/multi-configuration support source code control as well as the ability to interface to external build processes.The material presented in this application note foc
This application report presents phase noise data taken on the Texas Instruments' CDCE62005 jitter cleaner and synchronizer PLL. The phase noise performance of the CDCE62005 depends both on the phase noise of the reference clock and the CDCE62005 itself. This application report shows the phase noise performance at the most popular CDMA frequencies and helps the user to choose the right clocking so
In 1821 Thomas Seebeck discovered the physical phenomenon that when you join two dissimilar metalson both ends and heat one end a continuous current is created in the thermoelectric circuit . If the otherend is broken a voltage can be measured that is proportional to the temperature difference between theheated junction (measuring or hot junction) and the open end (reference or cold ju
How do I set and use interrupts on C for the Texas Instruments (TI)(tm) TMS320C6x DSP?Writing Interrupt Service Routines (ISRs) in C is straightforward as long as you follow the simple rules set out in this document. The problem consists of four parts: - Selecting the interrupt source and writing the ISR- Creating and initializing the interrupt vector table- Setting the proper register
The DRV411 is a signal-conditioning integrated circuit for use in closed-loop magnetic current-sensor modules. The DRV411 is designed to interface with symmetrical indium antimonide (InSb) and gallium arsenide (GaAs) type Hall sensors. Symmetrical Hall elements have their input and output impedances closely matched. The DRV411 contains excitation and conditioning circuitry that significantly red
This document presents an implementation of a hidden Markov model (HMM) speech recognition system using the 16-bit fixed-point TMS320C2xx or TMS320C5x digital signal processors (DSPs). It discusses system resource requirements vocal flexibility and future enhancements to this system. The application is verified using a TMS320C53 DSP platform.

The 'C5x DSK is designed to directly connect to a microphone and an 8-ohm speaker via RCA jacks. The I/O RCA jacks are directly connected to the dual A/D and D/A converter called the Analog Interface Circuit (AIC). In some instances the microphone does not generate the signal level required for the AIC to detect and convert the signal. It is suggested that a dynamic or amplified (pre-amp) microph
