LM49352RLX/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the codec near the audio connectors to minimize noise. Decoupling capacitors should be placed close to the power pins.
  • To minimize power consumption, use the lowest possible clock frequency, disable unused features, and use the power-down mode when not in use. Additionally, use a low-dropout regulator to minimize voltage drops.
  • A crystal oscillator or a high-quality clock source with low jitter is recommended. The clock frequency should be between 12.288 MHz and 24.576 MHz for optimal performance.
  • Use a shielded enclosure, keep the audio cables away from the digital lines, and use a common-mode choke to reduce electromagnetic interference (EMI). Additionally, follow good PCB design practices to minimize radiation.
  • The maximum allowed capacitance for the headphone output is 10 μF. Exceeding this value may cause instability or oscillation in the output stage.
