PCM2702EG4 datasheet by Texas Instruments

PCM2702EG4 Frequently Asked Questions (FAQs)

• What is the recommended clock source for the PCM2702EG4?
  The recommended clock source is a crystal oscillator with a frequency of 12.288 MHz or 11.2896 MHz, which is then divided internally to generate the required clock frequencies for the ADC and DAC.
• How do I configure the PCM2702EG4 for master or slave mode?
  The PCM2702EG4 can be configured for master or slave mode by setting the M/S bit in the control register. In master mode, the device generates the clock signals, while in slave mode, it receives the clock signals from an external source.
• What is the maximum input voltage for the analog inputs?
  The maximum input voltage for the analog inputs is 2.5V, which is the maximum voltage that can be applied to the ADC inputs without causing damage to the device.
• How do I implement a mute function for the analog outputs?
  The PCM2702EG4 has a mute pin (MUTE) that can be used to mute the analog outputs. When the MUTE pin is pulled low, the analog outputs are muted, and when it is pulled high, the outputs are enabled.
• What is the recommended power-up sequence for the PCM2702EG4?
  The recommended power-up sequence is to apply power to the digital supply (VDD) first, followed by the analog supply (VCC). This ensures that the digital circuitry is powered up before the analog circuitry.
