Base-band I2S interface frequency diversity

When the STA680 is paired with the TDA7786 or any tuner of ST STAR family it can benefit

from the supported base-band interface frequency diversity that allows to improve the EMI

robustness of the system.

The frequency diversity technique allows the base-band data-rate to be varied at run-time

depending on the frequency of the tuned station, thus moving the intrinsic radiation of the

BBI digital lines away from the signal of interest.
