This application note describes the implementation of multichannel echo control on a TMS320C62xx processor core that can cancel echoes with a 4-32-ms delay. This software is based on the leaky normalized least mean square (LMS) filter with either 16- or 32-bit weighting coefficients.
Design of a power supply for a high-performance point-of-load processor requires special attention to manage core and input/output (I/O) voltage sequencing which is critical to device operation and long term reliability. The TPS54x80 devices of low input voltage synchronous-buck dc/dc converters are designed for easily implementing sequential ratio-metric or simultaneous sequencing schemes. F
The bq34z100-G1 device is configurable to provide gauging for Li-Ion Li-Polymer LiFePO4 lead acid (PbA) NiMH and NiCd cell chemistries. The gauge can support charge and discharge currents up to 32 A pack capacities up to 29 Ah and pack voltages up to 65 V without special setups. This document provides information to setup the gauge to support packs that exceed these current capacity or vol

This application note describes an approach to design feedback loop compensation for an LLC resonant half-bridge power converter. The approach described here is based on the measured Bode plots of the modulator generated by a network analyzer. Frequency domain poles and zeros in the feedback loop compensation can be analytically determined then fine-tuned with a bench test. This measurement is ne
As new generations of microcontrollers lower their supply voltages from 5 V to 3.3 V and beyond issues with interfacing and noise are increasing. This application report presents cost-effective interfacing techniques for inputs and outputs of 3.3 V microprocessors in an automotive environment. In addition concerns about 3.3 V analog-to-digital converters (ADC) are discussed.

The enhanced DMA (EDMA) is a highly efficient and parallel data transfer engine. To make the best use of its resources it is necessary to understand the architecture and schedule transfers intelligently. This document details how to summarize analyze and schedule system traffic to produce efficient designs. An example audio/video system is presented and analyzed in full. Finally EDMA performan
This application report describes the Linux® operating system driver for the TSC2007 to help customers implement designs using the TSC2007 touch-screen controller. It also discusses the driver and associated code. The Linux driver code can be integrated into a customer's software system under different host processors. This driver has been tested and used on the Atmel AT91SAM9261EK platform.
Since the integration of high computational DSP power with all necessary motor control peripherals into a single chip, TMS320F240, it has become possible to design and implement a highly efficient and
The OMAP™5910 is a true system-on-a-chip device which consists of an ARM925T microprocessor unit (MPU) and TMS320C55x digital signal processor (DSP) cores. The device has many important peripherals necessary for luelessly interfacing with external devices in multimedia communication systems. One of the ports available is a eneral-purpose 16-bit parallel bus called EMIFS that is typically
Certain revisions of the prototype TMX320VC5510 DSP (hereafter referred to as VC5510) support an analog phase-locked loop (APLL) clock generator. This document provides a description of the programming and use of this APLL including the control register description how to program the APLL for the desired clock frequency and how to determine through software whether the device contains a digit
The LMZ35003 is a 7-V to 50-V input 2.5-A output integrated power module which integrates a DC/DCconverter shielded inductor and passives in a low-profile QFN package. For applications requiring greaterthan 2.5 A it is possible to parallel multiple LMZ35003 devices by following the recommendations in thispaper.
Hardware and layout limitations often require smaller package sizes that could potentially create a tradeoff for the number of serial peripherals available to the user. With the I2C protocol, special
