Audio sample rate converter

The TDA7786x is equipped with internal sample rate converters (SRC) that can be

configured to modify the sampling frequency of outgoing and incoming digital audio both in

the master and in the slave SAI mode (the native audio sampling frequency of the

TDA7786x is 45.6 kHz).

The SRC is able to automatically detect the input and output sampling rates and includes a

sample clock jitter rejection function which can be enabled separately. The input signal

word-width is 20 bits, while the output signal word width can be selected as 20 bits or 16

bits. In order to properly assist in the conversion, the SRC is coupled to self-adjusting low-

pass filters.
