Efficient Resampling Filters for the AIC111
Texas InstrumentsThe AIC111 is an ultralow-power fixed sample rate sigma-delta codec with a sample rate of 40 kHz and a usable bandwidth of 10 kHz. Typically most applications process data at sample rates of 8 kHz 16 kHz and 20 kHz. This requires that the DSP or microprocessor connected to the AIC111 decimate the incoming data from 40 kHz down to the required sampling frequency and interpolate the data back

Input Impedance Measurement Using ADC FFT Data
Texas InstrumentsTexas Instruments has introduced a family of high-speed analog-to-digital converters (ADCs) suited tomeet the demand for high-speed and high-IF sampling systems. To achieve the highest overall system performance an analog front-end circuit with an antialiasing filter must drive the ADC with the highestpossible dynamic range and lowest distortions. One important parameter of the front-end circ

Audio Demonstration on the DM642 EVM
Texas InstrumentsThe software demonstrates a g.729a voice codec running on the DM642 EVM. The demonstration collects stereo samples and plays back the resulting samples. The right channel samples are not modified and fed straight through. The left channel samples are fed through a g.729a encoding and decoding process and the resulting samples are played back.
The demonstration uses/features:
- Low pass

Driving Signals Over XAUI Backplanes Using DS42MB100, DS40MB200, or DS42BR400 (Rev. B)
Texas InstrumentsThis application report demonstrates how TI?s DS42MB100, DS40MB200, and DS42BR400 equalize XAUI backplane FR4 traces and reduce data dependent jitter to within XAUI specifications.
High Voltage Power Supply Using the Highly Integrated TPS61040
Texas InstrumentsThe TPS61040 is a highly integrated low-power boost converter capable of delivering output voltages up to 28 V. Additionally using a coupled inductor enables the TPS61040 to be used in applications where higher voltages are required - up to 75 V can be achieved.
Host USB Support on the DVEVM
Texas InstrumentsThe TMS320DM6446 device can be configured as a universal serial bus (USB) host or slave device. When configured as a host it can support USB mass storage devices such as USB flash drives which are widely used today to transfer pictures music and documents between PCs laptops and portable devices; however this support is not enabled by default. This document outlines the necessary steps for e
