PCM2705DB Frequently Asked Questions (FAQ)
-
The recommended clock source for the PCM2705DB is a crystal oscillator or a high-quality clock source with low jitter. The clock source should be able to provide a stable clock signal with a frequency of 12.288 MHz or 24.576 MHz, depending on the desired audio sampling rate.
-
To configure the PCM2705DB for master mode operation, set the MCLK pin to the desired clock frequency, and set the BCLK pin to the desired bit clock frequency. Then, set the WS pin to the desired word select frequency, and set the DOUT pin to the desired data output format. Finally, set the MODE pin to '1' to enable master mode operation.
-
The maximum cable length for the PCM2705DB's I2S interface depends on the clock frequency and the signal quality. As a general rule, the cable length should be kept as short as possible to minimize signal degradation and noise pickup. A maximum cable length of 10 cm to 20 cm is recommended for most applications.
-
The PCM2705DB has a power-on reset sequence that must be followed to ensure proper operation. The sequence is: VCC, then VREF, then MCLK, then BCLK, then WS, and finally DOUT. The power-on reset sequence should be followed in the order specified to prevent damage to the device or incorrect operation.
-
The recommended layout and routing for the PCM2705DB's PCB design involves keeping the analog and digital signal traces separate, using a solid ground plane, and minimizing the length of the signal traces. The MCLK, BCLK, and WS signals should be routed close to the device and away from noisy signals. The DOUT signal should be routed away from the device and towards the receiving device.
