The integrated circuit (IC) industry is converting to lead (Pb)-free termination finishes for leadframe-based packages. IC component users need to know the maximum length of time that components can be stored prior to being soldered. This study predicts shelf life of the primary Pb-free finishes being proposed by the industry. Components were exposed to a controlled environment with known aging a

This application report describes the implementation of the MPEG-2 video decoder on the TMS320C62x(tm)DSP. The MPEG-2 video standard specifies the decompression and coded representation for entertainment-quality digital video and is widely used in different digital video systems including DVB DTV DVD DSS etc. The decoder software implements all the MPEG-2 main-profile-at-main-level functional

This application report describes the implementation of a universal DSP module (UDM) to vocoders for a range of bit rates and to modems operating in the voice-band range. The UDM is based on the Texas Instruments (TI(TM)) TMS320C31 DSP. Difficulties in vocoder design are examined as well as measurement results for the HF modem under simulated HF channel environments. The error correction codi

Utilizing Ripple Steering in Forward and Flyback Converters and Input Filters

Current generations of telemcommunications infrastructure require intensive real-time computation. To meet the demands of next generation equipment such as 3G wireless base stations designers must seek methods to improve hardware and software efficiency.These real-time systems are typically distributed systems consisting of one master processor and one or more slave processors. Software flex

This document provides material composition listings of packing materials that are used by TI to ship products to customers. It lists substances contained in the manufacturing of packing materials wit

DC-Coupling Between Differential LVPECL, LVDS, HSTL, and CML

DSP education is established in the standard curriculum of most electrical engineering departments around the world. Since theoretical study is more or less standardized we looked for ways to involve students in practical design projects. The TI DSP Solutions Challenge gave us the opportunity to study design and implement a DSP system of moderate to high complexity. We chose the Texas Instr

Engineers often need to connect LEDs in parallel. Ideally, the LEDs share current equally. In reality, even LEDs from the same production lot have poorly matched I-V characteristics. This mismatch c

The TMS320C40 (?C40) DSP is a high-performance 32-bit floating-point parallel processor with CMOS technology. The ?C40 power supply currents vary with the specific application and device program activity. This document shows the user how to determine power supply current for the ?C40 under various operating conditions. Once the current is determined power dissapation can be calculated followed

The TPS40197 reference design is a synchronous buck converter providing VID programmable output voltage from 0.9 V to 1.2 V at up to 7 A from a 12-V or 5-V bus (4.75 V ~ 13.2 V). The design uses the TPS40197 – a synchronous buck controller with 4-bit VID interface for Smart-Reflex™ DSPs.

DN105 -- Upgrade from CC2510/11 Preview to Released Part

The most important task you must perform before starting ANY application is DSK initialization. Initialization is done in software preceding the entry to your application and must be done if the Analog Interface Circuit (AIC) is to be used.If this initialization is not done your DSK applications will not run properly. At other times the application seems to run but nothing will happen. For e

Efficient utilization of available memory in a TMS320C24x? DSP sometimes requires the placement of data in program space memory (as opposed to data space memory). In particular, the on-chip flash (or

This document describes how to use the multichannel buffered serial port (McBSP) in the Texas Instruments (TI)(TM) TMS320C6000 digital signal processors (DSP) to interface with devices that conform to the Inter-IC Sound (I2S) specification. I2S is a protocol for transmitting two channels of digital audio data over a single serial connection.The flexible McBSP in the TMS320C6000 supports the I
