Part Number: TAS5558

I have encountered an issue about using TAS5558 internal clock. I would like to configure the internal register but I can't find the corresponding register. could you tell me where to find these register?

Hi Linda,

Sorry i didn't make myself clear, here's the question:

1. I connect Pin MCLK to Pin SCLK, is this connection feasible? (in the red circle)

2. if it is feasible, the master clock is 3.072MHz, i would like to change it to 48kHz, which is used for sampling, how to configure the corresponding register?

Thanks

Best regards

Hi Ming,

I will follow the question of you.

You can connect SCLK to MCLK pin as clock input, the only requirement is the clock rate should be >= 3.072MHz. And the clock change is automatically detected by AMP internal OSC, so you doesn;t need to do any register setting.
