CLOCK Generation and PLL
The TLV320AIC3120 supports a wide range of options for generating clocks for the ADC and DAC
sections as well as the interface and other control blocks shown in Figure 5-33. 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 GPIO1 pins. The source reference clock for the codec can be chosen by programming
the CODEC_CLKIN value on page 0 / register 4, bits D1–D0. CODEC_CLKIN can then be routed through
