PCM1748E/2K Frequently Asked Questions (FAQs)
-
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 the device is properly initialized.
-
To minimize noise and EMI, it is recommended to keep the analog and digital signal traces separate, use a solid ground plane, and place decoupling capacitors close to the device. Additionally, use a shielded cable for the analog input signals and keep the clock signal traces away from the analog signals.
-
The maximum clock frequency that can be used with the PCM1748E/2K is 256 fs (3840 kHz), but it is recommended to use a clock frequency of 128 fs (1920 kHz) or lower to ensure optimal performance and minimize jitter.
-
To configure the PCM1748E/2K for master clock mode, set the MCLK pin to the desired clock frequency and set the BCK pin to the desired bit clock frequency. The device will then generate the LRCK signal internally.
-
The recommended termination scheme for the digital output signals of the PCM1748E/2K is to use a 50-ohm termination resistor to VCC or VDD, depending on the output signal level. This helps to reduce signal reflections and improve signal integrity.
