Product data sheet
8.1 System clock
Table 4:
The UDA1384 operates in slave mode only; this means that in all applications the system
must provide either the system clock (the bit clock for the voice ADC) or the word clock.
The audio ADC part, the voice ADC part and the DAC part can operate at different
sampling frequencies (DAC-WS and ADC-WS modes) as well as a common frequency
(SYSCLK, WSDA and DSD modes).
The voice ADC part supports a sampling frequency up to 50 kHz and the audio ADC
supports a sampling frequency up to 100 kHz. The DAC sampling frequency range is
extended up to 200 kHz with the range above 100 kHz being supported through 192 kHz
sampling mode, which halves the oversampling ratio of SYSCLK and internal clocks.
The mode of operation of the audio and voice channels can be set via the L3-bus or
I
When applied, the system clock must be locked in frequency to the corresponding digital
interface clocks.
The voice ADC part can either receive or generate the WSV signal as shown in
