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 latch-up conditions.
To configure the PCM1718E for Master Clock mode, set the MCLK pin to the desired clock frequency, and set the BCK pin to the desired bit clock frequency. Then, set the WS pin to the desired word select frequency, and set the SDIN pin to the desired serial data input. Finally, set the MODE pin to '1' to enable Master Clock mode.
The maximum allowed jitter on the Master Clock input is 500 ps peak-to-peak. Exceeding this limit may cause errors in the digital-to-analog conversion process.
Yes, the PCM1718E can be used with a separate analog power supply. In this case, the VCC pin should be connected to the digital power supply, and the VDD pin should be connected to the analog power supply. This can help to reduce noise and improve the overall performance of the device.
To implement a mute function using the PCM1718E, simply toggle the MUTE pin high to mute the analog output. When the MUTE pin is high, the analog output will be forced to a zero-volt level, effectively muting the audio signal.
