  Generating Low Phase-Noise Clocks for Audio Data Converters from Low Frequency
  PDF, 860 Kb, 档案已发布: 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.

  Troubleshooting I2C Bus Protocol
  PDF, 184 Kb, 档案已发布: 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
