This application report discusses the process of replacing the CLC016 reclocker with the LMH0026 reclocker.

Wireless Power is rapidly gaining momentum in the market place enabling a convenient new way to charge mobile devices. Qi compliant Wireless Power Transmitters (TX) present the foundation on which wireless power infrastructure is currently being built. This report aims at helping wireless power developers to make their first steps building practical wireless power systems. It outlines a step by st

This application report describes the process required to build the ARM® CMSIS DSP library in Code Composer Studio v6.1 with ARM Compiler version up to 5.2.5. This document also describes how to use Code Composer Studio v6.1 to build run and verify the 11 ARM DSP example projects that are included in the CMSIS package.

Auxiliary power (V aux) applications involve switching from one voltage source to another while maintaining uninterrupted power to the load. The Texas Instruments? TPS208x/9x family of power distribut

The TMS320 DSP Algorithm Standard (referred to as XDAIS) allows algorithms to make external references to functions implemented either in standard libraries or in other eXpressDSP-compliant libraries. However in some cases algorithms may be required to access specific functionalities that can be accomplished only in frameworks or in other externally linked modules.

This document discusses ho

Block floating-point (BFP) implementation provides an innovative method of floating-point emulation. This application report implements the BFP algorithm for the Fast Fourier Transform (FFT) algorithm on a Texas Instruments (TI) TMS320C54x DSP by taking advantage of the exponent encoder and normalization units on the DSP. The BFP algorithm as it applies to the FFT allows fractional signal gain adj

The PGA450-Q1 device must be optimized and fine-tuned for each particular application. All supporting materials provided by TI for the PGA450-Q1 have been optimized for Texas Instruments' lab-bench setup. The PGA450-Q1 device is not ensured to perform identically in an end-user’s test environment because of varying environmental factors.
These factors include temperature humidity air p

In recent years Passive Go (PG) systems for motorcycles have been developed that have been copied from automotive Passive Entry and Passive Start (PEPS) systems. But for bikes with no requirement to unlock doors or roll down windows at a distance such systems are over-designed with their UHF uplinks. The MCU RF group at Texas Instruments has developed a complete low-frequency approach to this pr

The switcher with integrated FETs (SWIFT?) TPS5461x family of internally compensated synchronous buck regulators offers a quick and easy solution to many power supply applications. These devices require a minimum of six additional components. The design procedure is simple and can be accomplished with the five basic steps outlined in this application report.

This design notes shows the hot swap designer how to control a ?5V rail using a UCC3919 Hot Swap Power Manager. This technique could also be applied using other positive Hot Swap Power Managers. Two c

The ISO120/121/122 isolation amplifiers (ISO amps) have a small (10-20mVp-p typ) residual demodulator ripple at the output. A simple filter can be added to eliminate the output ripple without decreasing the 50kHz signal bandwidth of the ISO amp.
