The recommended power-up sequence is to first apply the analog power supply (VDDA) and then the digital power supply (VDDD). This ensures that the analog circuitry is powered up before the digital circuitry.
The UDA1330 can be configured for master or slave mode by setting the appropriate values on the MCLK, BCLK, and WCLK pins. In master mode, the UDA1330 generates the clock signals, while in slave mode, it receives the clock signals from an external source.
The maximum clock frequency supported by the UDA1330 is 50 MHz for the master clock (MCLK) and 100 MHz for the bit clock (BCLK) and word clock (WCLK).
The UDA1330 has a built-in mute function that can be controlled by the MUTE pin. When the MUTE pin is set high, the output of the DAC is muted. Additionally, the mute function can also be controlled through the I2C interface by writing to the appropriate register.
The recommended layout and routing for the UDA1330 involves keeping the analog and digital signals separate, using a ground plane to reduce noise, and minimizing the length of the clock signal traces to reduce jitter.
