Application Notes
- Clocking Recommendations for DM6446 Digital Video EVM with Sngle PLL (Rev. A)PDF, 94 Kb, Revision: A, File published: Aug 8, 2007
The DM6446 (DaVinciв„ў) Digital Video Evaluation Module (EVM) requires a number of clock frequencies to run the system properly. The current clocking proposal of this EVM consists of a VCXO chip PI6CX100-27W, a PLL chip PLL1705, several voltage level translators, and a few oscillators or crystals. This application report discusses an optimized clocking proposal with Texas Instruments new clock driv - VCXO Application Guideline for CDCE(L)9xx Family (Rev.

This document presents a method to smoothly change frequency by IВІCв„ў protocol on Texas Instruments CDCE(L)949, CDCE(L)937, CDCE(L)925, CDCE(L)913 Clock Synthesizers, thus avoiding unnecessary intermediate frequencies. It also includes a code example to generate the IВІC protocol for the CDCE(L)9xx with the TMS320C645x. - Generating Low Phase-Noise Clocks for Audio Data Converters from Low FrequencyPDF, 860 Kb, File published: Mar 31, 2008
Generating a high-frequency system clock Fs (128fs to 768fs) from a low-frequency sampling clock fs (10 kHz to 200 kHz) is challenging, while attempting to maintain low phase jitter. A traditional phase-lock loop (PLL) can do the frequency translation, but the added phase jitter prevents the generated system clock signal from effectively driving high-performance audio data converters. This applica - Troubleshooting I2C Bus ProtocolPDF, 184 Kb, File published: Oct 19, 2009
When using the I2Cв„ў bus protocol, the designer must ensure that the hardware complies with the I2C standard. This application report describes the I2C protocol and provides guidelines on debugging a missing acknowledgment, selecting the pullup resistors, or meeting the maximum capacitance load of an I2C bus. A conflict occurs if devices sharing the I2C bus have the same slave address. This
