TAS5828M: Supported for input frequency 192KHz

Yasushi Fujiwara

Part Number: TAS5828M
Other Parts Discussed in Thread: TAS5825M,

Hello Experts,

My customer has question as follows. Would you answer it?
1. As you can see below photo(PPC3), "supported for input frequency 192K" is "X". Does it mean that PPC3 cannot support 192KHz? If it is supported for 192KHz, please tell which feature should be used.

2. Do you have documents about Process flow? It is available for TAS5825M. https://www.ti.com/lit/an/slaa786a/slaa786a.pdf
3. Do you have documents about Tuning guide? It is available for TAS5825M. https://www.ti.com/lit/an/slaa894/slaa894.pdf

Best Regards,
Fujiwara

Hello Fujiwara,

We do not have a separate tuning guide for the TAS5828M, but let me check in internally about a process flow document we can provide.

best regards,

Luis

Hello Luis,

Thanks for reply. I will wait your reply.

Also how about input sampling rate question? Latest PPC3 can support 192KHz input sampling rate? The datasheet stated that TAS5828M support 192KHz input sampling rate, so PPC3 should be support it, I think.

Best Regards,
Fujiwara

Hi Fujiwara

We haven't built this function into PPC3. To support 192KHz needs a lot of DSP resource, which means we need to develop a new process flow, cut off some of the functions and support 192KHz. We haven't got enough requirement from customer to decide which function should be cut off.

If you have solid requirement from customer, welcome to e-mail to us, tell us more details of the customer's project and needs. Thank you.
