2.5 Clocks, Digital Phase-Locked Loop (PLL), and Serial Data Interface  
These modules provide the timing and serial data interface for the TAS3202. The clocking system for the  
device is illustrated in Figure 2-1. The TAS3202 can be either clock master or clock slave depending on  
the configuration. However, clock master mode is the primary mode of operation.

Figure 2-1. Clock Generation  
DISCLAIMER: Analog performance is not ensured in slave mode, as the analog performance depends  
upon the quality of the MCLK_IN. The TAS3202 is not robust with respect to MCLK_IN errors (glitches,  
etc.); if the MCLK_IN frequency changes under operation, the device must be reset.  
I2C clock master operation:  
External 512Fs crystal oscillator is used to generate all internal clocks plus all clocks for external  
asynchronous sampling rate converter (ASRC) output (if external ASRC is present).  
LRCLK_OUT is fixed at 48 kHz (Fs).  
SCLK_OUT is fixed at 64Fs.  
MCLK_OUT is fixed at 256Fs. In master mode, the external ASRC converts incoming serial audio data  
to 48-kHz sample rate synchronous to the internally generated serial audio data clocks.  
In master mode, all clocks generated for the TAS3202 are derived from the 24.576-MHz crystal. The  
internal oscillator drives the crystal and generates the main clock to digital PLL (DPLL), master clock  
outputs, 256Fs clock to the ADC, and 128Fs clock to the DAC. The DPLL generates internal clocks for  
the DAP and the 8051 microprocessor.
