... Low power audio DAC 8 FUNCTIONAL DESCRIPTION 8.1 System clock The UDA1334TS operates in slave mode only; this means that in all applications the system must provide the system clock and the digital audio interface signals (BCK and WS). The system clock must be locked in frequency to the digital interface signals ...
