TAS5414C-Q1 Frequency Response of PSRR

Hi Kato,

We will look into this and get back to you.

Hi Gregg-san,

Thank you for your quick response.
It seems that the files which you sent to me are the crosstalk characteristics for TAS5414B-Q1.
Is that my misunderstanding?
Could you please send the frequency response of PSRR for TAS5414C-Q1 to me including the on/off condition of the enhanced crosstalk function?

Best Regards,
Kato

Hi Gregg-san,

Thank you for your reply.
I had a concern about the files since it seemed that those are the characteristics of crosstalk.
Are those the frequency response regarding the PSRR although I will confirm them just in case?

Best Regards,
Kato

Hi Gregg-san,

Thank you for explaining so politely.
I understood and will inform our customer of these information which I have obtained from you.

Best Regards,
Kato

Hi Gregg-san,

I have one more quesiton.
The PSRR is not degraded when enabling the enhanced crosstalk function although I compared with the on/off conditions for the enhanced crosstalk function, conversely is improved it.
On the other hand, I have heard from you the other day as below.
Could you please tell me this reason?

"The Crosstalk Enhancement is a function that improves the crosstalk, but also slightly degrades the THD and PSRR performance."

Hi Gregg-san,

Thank you for explaining so politely.
I will confirm it again, contact you if I have any questions.

Hi Gregg-san,

That looks like that the PSRR is not degraded when enabling the enhanced crosstalk function to me although I reviewed them again.
Is that my misunderstanding?

Hi Gregg-san,

Thank you for your reply.
I understood that the PSRR is degraded at 1kHz, may be not degraded in other case since you do not guarantee the full audio frequency band.

Best Regards,
Kato
