The UCC3972 CCFL controller provides the necessary circuit blocks to implement a highly efficient CCFL backlight power supply in a small-footprint, 8-pin TSSOP package. This design note describes the

This document provides guidelines for identifying and solving common problems associated with the collection of high-speed data. On a trace-capable device the trace interface is one of the highest performance interfaces. Although only used during design development and debug the trace interface must be implemented correctly to achieve full functionality and optimal performance.

The spectrum of bus-interface devices with damping resistors or balanced/light output drive currently offered by various logic vendors is confusing at best. Inconsistencies in naming conventions and methods used for implementation make it difficult to identify the best solution for a given application. This report attempts to clarify the issue by looking at several vendors? approaches and discussi

Certain features of the TMS3320C54x? architecture and instruction set facilitate the solution of numerically intensive problems. Some examples include filtering encoding techniques in telecommunication applications and speech recognition. This application report discusses digital filters that use both fixed and adaptive coefficients and fast Fourier transforms.

TMS320DM365TPS74801TPS74701 Simple Power Solution Using LDOs For TMS320DM365 Processor

Dynamically selecting the desired bus configuration and format is useful for systems such as network switches and routers that use 32-to 36-bits of data or 8- and 16-bit controllers and buses. The SN74ABT3613 FIFO provides a unidirectional data path with bus-matching and byte-swapping on Port B while the SN74ABT3614 FIFO provides a bi-directional data path with bus-matching and byte-swapping in e

Many FIFOs being released today include programmable almost-empty and almost-full flags. TI?s newly released SN74V2x5 FIFOs are functionally equivalent to devices offered by IDT and are pin-for-pin compatible. The programmable flags can be used to provide interrupt signals when used in digital signal processor (DSP) and microprocessor applications. Additional configurations use the programmable fl

Realistic wireless channel models consider the impact of multipath propagation. Since a transmitted signal is subject to reflections and refraction on walls surfaces and so forth the receiving node will see signals differing in phase and amplitude. Using more than one antenna allows the evaluation of different multipath scenarios to avoid or reduce the effects of fading and interferences. Diver

This application report describes and shows how to implement a direct thermocouple interface, without using the signal conditioning circuitry normally required for thermocouples. The thermocouple inte

This document discusses the power consumption of the Texas Instruments TMS320DM6441 digital media System-on-Chip (DMSoC). Power consumption on the DM6441 device is highly application-dependent so a spreadsheet is provided to model power consumption for a user’s application. To get good results from the spreadsheet realistic usage parameters must be entered. The low-core voltage and other power d

The TLC320AD57C (?AD57C) is a sigma-delta stereo A/D converter providing 18-bit resolution with a signal-to-noise ratio of 97dB and a dynamic range of 91 dB. The device consists of two synchronous conversion path with a decimal decimation filter following the 64X oversampling sigma-delta modulator.

This document provides an overview of a PLL clock driver. The advantages and disadvantages of PLLs and the cost in designs are discussed. TI manufactures three low-voltage high-performance PLL clock drivers the CDC2582 CDC2586 and the CDC2586.

Phase Locked Loop (PLL) is a fundamental part of radio wireless and telecommunication technology. The goal of this document is to review the theory design and analysis of PLL circuits. PLL is a simple negative feedback architecture that allows economic multiplication of crystal frequencies by large variable numbers. By studying the loop components and their reaction to various noise sources we

Wireless phones continue to gain additional features making them more valuable to the end user. Many of these features involve increased audio functionality and hence some additional design effort on the audio portion of the phone. This paper gives an overview of audio amplifiers before describing different audio architectures that can be used to implement features like ear-bud speakers stereo

MSP430 microcontrollers are designed specifically for ultra-low-power applications. Features such as multiple low-power modes instant wakeup intelligent autonomous peripherals and much more to enable such ultra-low-power capabilities.
