This document describes how to interface the multichannel buffered serial port (McBSP) in the TMS320C6000? digital signal processor (DSP) to a voice band audio processor (VBAP). The VBAP under discussion is the TI TLV320AC56 3V 2.048 MHz audio processor which is a m-law companding device. The interface is also applicable to TI?s TLV320AC57 an A-law companding audio processor.The highly
The DAC8534 is a quad-channel, low-power, 16-bit, serial digital-to-analog converter. This application report presents a method for interfacing the DAC8534 to the TMS320C6x-series DSKs using McBSP1 an
This technical brief is an overview of the low power architectural features and design considerations of the TMS320LC54x DSP (Digital Signal Processor) family. For those with a deeper interest in low-power DSP design this technical brief also provides an overview of a more detailed application brief titled Calculation of TMS320C54x Power Dissipation TI literature number SPRA164. The audience
This application report reviews the design steps used in the evaluation module (EVM) UCC25230EVM-754. The EVM helps evaluate the UCC25230 pulse-width modulation (PWM) controller in a forwardflyback or Flybuck™ dc-dc converter topology for a 48-V telecom bias supply. The EVM is a dual-output converter with 1500-VDC isolation between the two outputs. Each output is typically rated as 12 V and 65 m
The installation and configuration of a system can be a major problem for the user as a result of the wide variety of different plug-in boards and computer systems which are in use. The ISA (Industry Standard Architecture) bus is a widely used standard in the PC industry. The ISA bus architecture requires the allocation of resources. These include the I/O address space a memory address space th
This application report describes the concepts and benefits of SmartReflex™ technology implemented in the DM6467 device. Two reference power supply designs that support the SmartReflex feature are also discussed. With the SmartReflex feature enabled an average of 1W in power savings can be achieved for strong devices. The included reference designs show that additional components are requir
This application report describes the implementation of a three-phase electronic electricity meter using MSP430 4xx family of microcontrollers. The implemented functions are RMS voltage for each phase
Double data rate (DDR) bus termination power requirements bring new challenges to the power supply by requiring voltage tracking of a reference supply requiring both sourcing and sinking current and maintaining a high efficiency over a wide current range. This paper address these issues while presenting an example DDR design of 12 A of output current with voltage outputs between 0.9 V and 1.25 V
Bit-reversed addressing mode normally requires that the n-element array be aligned on an n-word boundary. When n is large this may result in a large hole in the memory map. To enable more efficient use of memory a technique to use bit-reversed addressing without data alignment is presented.
A bipolar 12V supply from a single +5V input can be developed using a number of conventional approaches. A boost converter is the most logical for the +12V output; however, it cannot be used in some i
This application report presents a method for interfacing the TLC320AD535 and TLC320AD545 codecs from Texas Instruments (TI)(tm) with the multichannel buffered serial port (McBSP) on TI's C54xx family of digital signal processors (DSPs). As is the case with many codecs from TI these devices utilize a primary and secondary communication protocol to differentiate between actual signal data and code
