ZHCS986B May 2012 – December 2018 TLV320DAC3203
The TLV320DAC3203 supports a wide range of options for generating clocks for the DAC as well as interface and other control blocks. The clocks for the DAC require a source reference clock. This clock can be provided on a variety of device pins such as MCLK, BCLK, or GPIO pins. The CODEC_CLKIN can then be routed through highly-flexible clock dividers to generate the various clocks required for the DAC sections. In the event that the desired audio clocks cannot be generated from the reference clocks on MCLK, BCLK, or GPIO, the TLV320DAC3203 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 TLV320DAC3203 provides several programmable clock dividers to help achieve a variety of sampling rates for the DAC.
