PCM1800E Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the analog input signals. This ensures that the internal voltage regulators are powered up correctly.
  • The analog input filter should be designed to reject noise and interference above 20 kHz. A simple RC filter with a cutoff frequency around 10 kHz to 15 kHz is recommended. The filter should also be designed to minimize signal attenuation and distortion.
  • The recommended clock frequency for the PCM1800E is 256 times the sampling frequency. For example, for a sampling frequency of 44.1 kHz, the clock frequency should be 11.2896 MHz (256 x 44.1 kHz).
  • The PCM1800E outputs 24-bit data in MSB-first format. The data should be latched on the rising edge of the BCK (bit clock) signal. The data is output in a continuous stream, with the MSB of each sample output first, followed by the remaining 23 bits.
  • The PCM1800E is a high-speed, high-resolution ADC, and as such, it requires careful layout and routing to minimize noise and interference. The analog input traces should be kept short and away from digital traces. The power supply traces should be wide and well-decoupled. The clock traces should be short and matched in length to minimize skew.
