The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the device.
To configure the PCM2707 for master mode operation, set the MCLK pin to the desired clock frequency, and then set the BCLK and LRCK pins to the desired bit clock and frame clock frequencies, respectively. Additionally, set the MODE pin to logic high to enable master mode.
The maximum allowed capacitance on the VCC and VDD pins is 10uF. Exceeding this value may cause power-up issues or affect the device's performance.
The PCM2707's digital output data format is in I2S (Inter-IC Sound) format. The device outputs 24-bit or 16-bit data, depending on the configuration, with the most significant bit (MSB) first. The data is output on the DOUT pin, and the clock signal is output on the BCLK pin.
It is recommended to keep the analog and digital signals separate and use a multi-layer PCB with a dedicated ground plane to minimize noise and crosstalk. The analog signals (VCC, VDD, and analog output) should be routed away from the digital signals (clock, data, and control signals) to prevent noise coupling.
