The recommended power-up sequence is to apply VCC first, followed by VDD, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly and prevents any potential damage to the device.
To configure the PCM2705CDBR for master mode operation, set the MCLK pin to the desired clock frequency, and then set the BCLK and LRCLK pins to the desired bit clock and left-right clock frequencies, respectively. Additionally, set the MODE pin to a logic high to enable master mode.
The maximum allowed capacitance on the VCC and VDD pins is 10uF. Exceeding this value can cause power-up issues and affect the device's performance.
The PCM2705CDBR outputs 24-bit audio data in I2S format. The digital output data should be handled according to the I2S protocol, with the left and right channel data multiplexed on the DOUT pin, and the bit clock and left-right clock signals provided on the BCLK and LRCLK pins, respectively.
The recommended layout and routing for the PCM2705CDBR involves keeping the analog and digital signal paths separate, using a solid ground plane, and minimizing the length of the clock signal traces. Additionally, it is recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
