TAS2560: 96 KHz configuration

Jakob Bergmeier
Prodigy 25 points
Part Number: TAS2560

Hi all,

I am trying to configure the TAS2560 with the PPC3. Unfortunately there is no option in the End System Integration to choose a sample rate of 96 KHz. 

I tried to write the registers (0x36 to 0x33 and 0x04 to 0x1*) with the Register Map tool but without any success.

Are there any options or registers I am missing? Could you please provide some further information or a complete config file therefore?

Thanks in advance! Best,

Timo

    Hi Jakob,

    You may also need to set the device in Mode 2 by setting register 0x02, as described in data sheet: https://www.ti.com/lit/ds/symlink/tas2560.pdf#page=44&zoom=100,0,96

    I'll do some tests on my side and will let you know the results and required configuration later this week.

    Hi Jakob,

    Just a follow up on this thread:

    • You need to set MODE 2 in register 0x02, although I tried modes 1 and 3 and it's still working
    • Please notice that Class-H is not available in this mode, although you can still use the boost by setting PWR_DEV bits to "01"
    • You need to set PCM_RATE bits to "11" on register 0x36 to select 96kHz

    An example script is included below:

    w 98 00 00
w 98 7f 00
w 98 01 01
d 10

w 98 00 00
w 98 7f 00
w 98 00 00
w 98 15 02
w 98 00 00
w 98 7f 00
w 98 36 33
w 98 02 02
w 98 07 41

w 98 00 00
w 98 7f 00
w 98 07 40
