APPLICATION INFORMATION
VA represents the maximum available digital mW output response (VA = 1.06 Vrms).
VOD = A × VA
where A =
1 + (R1/R2)
4 + (R1/R2)

higher clock frequencies and sample rates
The TCM320AC46 is designed to work with sample rates up to 24 kHz where the frequency of the frame sync
determines the sampling frequency. However, there is a fundamental requirement to maintain the ratio of master
clock frequency, fCLK, to frame sync frequency, fFSR/fFSX. This ratio for the device is 2.048 MHz/8 kHz or 256
master clocks per frame sync. For example, to operate the TCM320AC46 at a sampling rate of fFSR and fFSX
equal to 16 kHz, fCLK must be 256 times 16 kHz, or 4.096 MHz. If the TCM320AC46 is operated above an 8-kHz
sample rate, however, it is expected that the performance will be degraded.
