This document provides the interface circuit for each of the microcontrollers and the assembler code listings for each interface. An overview of analog considerations for

SB-100 Subscriber Line Card for Central Office Telephone Switching Equipment

Electromagnetic Interference (EMI) is an unwanted effect between two electrical systems as a result ofeither electromagnetic radiation or electromagnetic conduction. EMI is the major adverse effect caused bythe application of switch-mode power supplies (SMPS). In switching power supplies EMI noise isunavoidable due to the switching actions of the semiconductor devices and resulting disconti

This document is a compilation of frequently asked questions regarding the TUSB6250 USB 2.0 to ATA/ATAPI Bridge Controller.

This document is an overview of the use of the I2C slave function set for MSP430 devices with the USCI module. The functions provided in the package can be used for MSP430 slave devices performing I2C

Gallium Nitride (GaN) based power FETs are finding increasing use in high efficiency power converters. GaN FETs provide zero reverse recovery charge (Qrr) and very low gate charge. These features resu

This application report describes how to interface the DAC7731 digital-to-analog converter to the MSP430F149 microcontroller.

The TPS61020 is a highly integrated low-power boost converter ideally suited for portable battery-powered equipment. To improve start-up performance from a power-limited source such as a battery the TPS6102x family uses different steps and modes to reduce demand on the battery. This prevents the battery bus from sagging during start-up and improves start-up operation at low voltage.

The 'ALVCH16244 is a 16-bit advanced low voltage CMOS (ALVC) unidirectional driver. Typically data sheet values for tpd ten and tdis are characterized under a 50-pF capacitive load with a temperature range of -40?C to 85?C. At times these drivers are used in memory addressing for dual in-line memory modules (DIMM) with a 10-pF load and and temperature range of 0?C to 70?C. This document provide

Low Power Wireless Radio as a technology is of great application to many of the products where wireless connectivity is needed. But the world of RF is completely different from the conventional development environment perspective as the frequencies involved make the testing of such systems more complex. Texas Instruments has a huge portfolio of Low Power Wireless Simple Link solutions catering th

This report discusses implementation of the PID and deadbeat controllers with the TMS320 family of DSPs. These application-specific processors are designed to process signals including control signals very efficiently.The report covers the following topics:- Control Systems - Analog Controllers - Digital Controllers - Analog versus Digital Controllers- Process

This document provides a brief review of the fast Fourier transform (FFT) algorithm and its extension to two dimensions then focuses on parallel implementations of 2-D FFTs. It presents a TMS320C40 32-bit parallel digital signal processor (DSP) implementation of parallel 2-D FFT using the TMS320C40 development tool (PPDS). The appendices provide the C and TMS320C40 assembler source code for perfo

This document assists in the estimation of power consumption for the TMS320VC5501 and TMS320VC5502 digital signal processors (DSPs). As power consumption can vary widely on these devices, a spreadshee

Many types of wires are widely used to transmit data. Specifically Category 3 and Category 5 (Cat3 and Cat5e respectively)—also known as unshielded twisted pair or UTP lines—are now recommended for new telephone installations. Coaxial (coax) cables are used to distribute cable television (CATV) signals throughout a home. #12 and #14 American wire gauge (AWG) electric power distribution wire is a
