This application report describes the use of TMS320C5402 DSP to interface to Sigmatel STAC9721 AC97 Codec. In the AC97 interface standard the codec will supply a BITCLK to a digital controller for it to generate a Frame Sync (FSYNC) that is synchronized to the received BITCLK. The digital controller in this context is the TMS320C5402 DSP and FSYNC is generated from the Sample Rate Generator (SRG
The TPIC6C596 is a serial-in parallel-out, Power+ Logic <TM> 8-bit shift register with low-side switch DMOS outputs rating of 100 mA per channel. The device is designed to drive resistive and inductiv
This application report provides explanations and design considerations for interfacing RS-422 differential current mode logic (CML) differneital emitter coupled logic (ECL) and single-ended drivers with low-voltage differential signal (LVDS) receivers.
The HEX30 utility takes a TMS320C3x/TMS320C4x COFF file and converts it into a PROM programmer (i.e. Intel Motorola and ASCII formats) file. This document describes how to link this output file to the rest of an assembly language application. It is suggested that using the Intel or ASCII formats when trying to link this data with your application will be the most effective path. The document inc
This application report describes the implementation of a three phase electronic electricity meter using the Texas Instruments MSP430F471xx system-on-chip (SOC) processor. This application report incl
This document describes issues of interest related to migration from the TMS320VC5409 to the TMS320VC5409A. The objective of this document is to indicate differences between the two devices. Functions that are identical between the two devices are not included. For detailed information on the specific functions of either device refer to the device data sheets 5409(SPRS082) 5409A (SPRS139) the
Provides curves for the predicted MTBF vs the ambient operating temperature for the PT3100/4100 isolated products. The note also includes a discussion on the reliability cal-culation methods the physical construction and a block diagram of the product.
This document describes the problems that occur when making timing measurements with fast logic circuits. An introduction to impedance matching and the determination of stripline impedance along with the requirements for an efficient test setup is provided. An example of the test setup with the test results is included in this document. The appendix contains descriptions of the ac-performance boa
Modern day electronic devices, such as cell phones and MP3 players, can usually be powered with either an adapter or USB source through a single input connector using a mini USB cable. For a simple ch
