This document supplies information for using the Expansion Bus Module (EBM) on the TMS470R1B1M to interface to external memory and peripherals. The module supports the multiplexing of the input/output (I/O) functions and the expansion bus interface. When the I/O functions are not used the EBM can be used to interface 8- or 16-bit memories.

Low-Voltage Differential Signaling Yields Megatransfers per Second with Milliwatts of Power

RS-485 is a widely used standard for industrial communication due to its simplicity and suitability for use in high-noise environments on long cables. Inherent in the standard are balanced signal drivers and receivers which use differential signaling to reject common-mode noise. Receiver hysteresis is commonly used to ensure glitch-free reception even when differential noise is present. This appl

The TPIC6595 is a monolithic device that contains eight 1.5A/45-V low-side DMOS power switches combined with the logic functions of an SN74HC595 and packaged in a 20-pin dual in-line plastic package (DIP) or wide body surface-mount package (DW). The TPIC6595?s outputs are inverted relative to those of the SN74HC595. This document provides a functional description of the TPIC6595 and detailed app

This application note describes how to realize an Electrical Echo Canceller using the LMS instruction of the TMS320LC54x series DSP. Thanks to this compact instruction it is possible to perform the Prediction Filter (FIR) and the weight updating at the same time. The software described is based on the Leaky Normalized Least Mean Square adaptive (LNLMS) filter with single precision (16 bit) coeff

DN010 -- Close-in Reception with CC1101

This application report provides basic circuits of the Texas Instruments op amp collection.

High-performance signal processing devices such as FPGAs and DSPs require multiple power supply voltages for operation. The order and timing in which these supply outputs power up and down is usually specified. A design example using the TPS54380 is shown for the case where the power supply to be tracked is also the input voltage to the TPS54380. Information is provided for adjusting the start-u

This application note addresses a method to OR the high side of the power source as well as the low side using N-channel MOSFETs, thus replacing diodes D1 and D2 with more efficient MOSFETs in the hig

This application note provides Pin Open and Short Test Results for the device pins of the TPS54xx0-Q1and TPS57xx0-Q1 family of step-down SWIFT™ DC-DC converters. The TPS54xx0-Q1 and TPS57xx0-Q1 family of power devices consists of high-input-voltage step-down regulators that provide a variety ofcurrent options.

Resistive elements configured as Wheatstone bridge circuits are used to construct force and pressure sensors. The resistive elements used to make the bridge change resistance in response to mechanical strain.This report discusses the basic concepts of resistive bridge sensors and three circuits commonly used for signal conditioning their output.

The RapidIO® Message Queue Transport (MQT) allows applications to communicate to other TI DSP processors via serial RapidIO. The RapidIO MQT plugs into the MSGQ module of DSP/BIOS. The RapidIO MQT module uses the messaging logical layer of RapidIO to send MSGQ messages between processors. The MSGQ module manages the communication with the MQTs off-loading that burden from the application. The

The G.726 is a voice-compression algorithm standard defined by the International Telecommunication Union (ITU). It can be used in many applications such as digital cordless telephones radio/wireless local loop and pair-gain. The software package described in this application report is plug and play compliant with the multichannel framework using the TMS320C54x DSP.

The TI D-CAP™ Mode controller is widely used in computing power management. D-CAP™ Mode requires an appropriate amount of equivalent series resistance (ESR) on output capacitors to ensure the loop stability. However many customers prefer to use a low-ESR capacitor such as a ceramic output capacitor. Sufficient output ripple however may not be available in this case to ensure the system stabili

The Burr-Brown REF102 is a buried-zener-based precision 10.0V reference. It has better stability and about five times lower output noise than band-gap-based voltage references such as the PMI REF-10. Still its output noise is about 600uVp-p at a noise bandwidth of 1MHz (the output noise of the PMI REF-10 is about 3000uVp-p at 1MHz).
