PCM1750U Frequently Asked Questions (FAQ)
-
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 minimize noise and EMI, it is recommended to keep the analog and digital grounds separate, use a solid ground plane, and keep the signal traces short and away from the power traces. Additionally, use decoupling capacitors on the power pins and consider using a shielded enclosure for the PCB.
-
The maximum clock frequency that can be used with the PCM1750U is 256 fs (384 kHz), but it is recommended to use a clock frequency of 128 fs (192 kHz) or lower to ensure optimal performance and minimize jitter.
-
To configure the PCM1750U 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 configure the serial data format using the SDF pin.
-
The recommended termination scheme for the PCM1750U's digital outputs is to use a 50-ohm termination resistor to ground, and to use a series resistor of 22-33 ohms to limit the output current and prevent damage to the device.
