TAS6511-Q1: To Enable Hybrid Modulation

CH Wong

Part Number: TAS6511-Q1

Tool/software:

Hi,

I would like to enable the Hybrid Modulation mode and from the datasheet has limited information.

Q1) It mentioned that this mode need to be activated in DSP memory but I couldn't find any DSP memory book and page registers details?

Q2) What is the switching frequency, PVDD supply voltage and output impedance that are dependent when using this mode?

Please advise

Thank you

Hi CH

After check within the team, this description in the datasheet not fully correct, it's possibly for early samples.

For the final RTM part, no need to use additional DSP register settings. Just at 0x02 register choose Hybrid would be fine.

Hi Shadow,

Thank you for clarify that. I assume that we do not need to set the switching frequency, PVDD voltage and impedance.

What about the DSP memory book and page registers details? most of the digital audio processing capabilities for this device required to written into DSP memory.

For example the Gain Compensation Biquads where it required to written the respective coefficients in the DSP memory , hence it will be helpful to have the details to ensure we write into the correct range/registers.

I'll check it with software team, they would prepare a table of all of DSP registers. Will give you before this Friday.
