  • Usage of I2C for CDCE(L)949, CDCE(L)937, CDCE(L)925, CDCE(L)913
    PDF, 297 Kb, File published: Sep 23, 2009
    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 Frequency
    PDF, 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 Protocol
    PDF, 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
