Hi there,

We use a TAS5782m as i2s master, CSR8675 as slave, initial setting are SCLK =3.072MHz, LRCK =48KHz, standard i2s.

and when we play the audio stream at sample rate=96KHz, the audio stream output from TAS5782m is not correct.

can TAS5782m auto detect the input sample rate and output the correct audio stream?

thanks

hello,

The TAS5782 supports 96k and 96k->48k SRC.

Hi Linda,

can the TAS5782 output a 96k LRCK signal as master mode?

we use TAS5782 as master mode in our system, and play 3 kind of sampling rate audio stream, 44.1K, 48K and 96K.

and we now use a 12MHz as PLLCLKIN, but can not make a 96k LRCK output signal.

thanks

hi, Lin,
can you share us whole application block diagram? do you want to use TAS5782 as signal source? TAS5782 normally working in slave mode.

regards
Linda
