Working Principles

The PCM1864QDBTRQ1 operates by receiving analog audio signals through its analog inputs (AINL and AINR). These signals are then converted into digital format using high-resolution ADCs. The converted digital audio data can be accessed through the digital audio output (DOUT) pin.

The device requires a master clock (MCLK) input to synchronize the conversion process. Bit clock (BCLK) and left/right clock (LRCLK) signals are used to control the timing of data transmission.
