9.3.7 Clock Generation and PLL

The TLV320AIC3204 supports a wide range of options for generating clocks for the ADC and DAC sections as well as interface and other control blocks. The clocks for ADC and DAC require a source reference clock. This clock can be provided on variety of device pins such as MCLK, BCLK or GPI pins. The CODEC_CLKIN can then be routed through highly-flexible clock dividers to generate the various clocks required for the ADC and DAC sections. In the event that the desired audio clocks cannot be generated from the reference clocks on MCLK, BCLK or GPIO, the TLV320AIC3204 also provides the option of using the on-chip PLL which supports a wide range of fractional multiplication values to generate the required clocks. Starting from CODEC_CLKIN the TLV320AIC3204 provides several programmable clock dividers to help achieve a variety of sampling rates for ADC, DAC and clocks for the processing block.

To minimize power consumption, the system ideally provides a master clock that is a suitable integer multiple of the desired sampling frequencies. In such cases, internal dividers can be programmed to set up the required internal clock signals at very low power consumption. For cases where such master clocks are not available, the built-in PLL can be used to generate a clock signal that serves as an internal master clock. In fact, this master clock can also be routed to an output pin and may be used elsewhere in the system. The clock system is flexible enough that it even allows the internal clocks to be derived directly from an external clock source, while the PLL is used to generate some other clock that is only used outside the TLV320AIC3204.
