This application report summarizes the necessary steps to setup the direct memory access controller (DMA) to transfer data between the SCI and the data RAM of the microcontroller freeing the CPU during the entire message transmission. Detailed code examples are provided as guidelines for the different setup steps.

DRV2605 DRV2605 Device Setup Guide

Thermal metrics such as qJA and qJC are used to compare thermal performance of plastic integrated circuit (IC) packages. The thermal conductivity of all materials of the IC packaging and of the test board affect the thermal resistance values reported by semiconductor manufacturers. Recent advancements in reporting thermal data include standard test-board designs. Texas Instruments (TI) has publi

Current sensing in power supplies and motor controls demand the use of a very low value resistor. Each application varies in need for resistance value power rating size form factor inductance temperature coefficient and accuracy. To meet some of these applications the copper of a printed circuit board (PCB) can be utilized but has some distinct limitations. This design note provides design

Supporting HDMI 1.3 12-bit deep color with the TMDS341A

This report describes an all-digital implementation of an AGC on a TMS320C17 DSP. The AGC is designed specifically for modem applications.- The first section provides an overview of modem receiver structure and implementation.- The second section discusses the AGC block diagram and the motivation for using an AGC in a modem receiver.- The third section covers the AGC hardware and s

The first section describes the impact of the clock jitter introduced by the analog phase−locked loop module (ZPLL) on the system clock (SYSCLK) and the peripheral clock (ICLK). In the second section the resulting impact on the CAN communication is explained.

The UCC28019A and its predecessor the UCC28019 are eight-pin active power factor correction (PFC) controllers that use the boost topology and both operate in continuous current conduction mode.

The DP83640 provides a highly precise low-jitter clock output that is frequency-aligned to the masterIEEE 1588 clock and can be phase-aligned as well. Empirical testing shows very low jitter (less than 1 nspeak-to-peak and standard deviation when using the FCO source) and precise phase alignment. Whiletest results show that the FCO has superior long term jitter performance using the PGM as

Single- and Double-Cell Low-Dropout Lithium-Ion Charger Using the bq2056

Video Interface Design White Paper

A nickel/palladium (Ni/Pd) lead finish for integrated circuits (IC) was introduced in 1989. In 1998 solderability test results were published on Ni/Pd-finished components using a Sn/Ag/Cu/Sb lead-free (Pb-free) solder paste and printed wiring board (PWB) pads coated with organic solderability preservative (OSP). Since then a number of other Pb-free solder alloys have been introduced.This evalu

200-W Interleaved Forward Converter Design Review Using TI's UCC28221 PWM Controller

The LMH6515 is a fully differential amplifier optimized for signal path applications up to 400 MHz and hasa 200Ω input.

This application report presents a method for utilizing the on-chip pulse width modulated (PWM) signal generators on the TMS320F280x™ family of digital signal controllers as a digital-to-analog converter (DAC). The method involves analog low-pass filtering the PWM signal to remove high frequency components leaving only the low-frequency content. Theoretical and experimental results are presented
