Notes:
3.
Pseudo-random noise with triangular probability density function. Bandwidth up to 10MHz.
4.
Guaranteed by characterization.
5.
Assuming that 120dB(SPL) is mapped to 0dBFS.
6.
Assuming an input of -45dBV
7.
Guaranteed by design.
8.
All parameters are tested at 2.4MHz. Frequency range guaranteed by characterization.
9.
Device wakes up when fCLK 300kHz.
