Hi MIYAOKA-san

The Master clock is the Main frequency for TAS6424E device, it's internal digital circuit need to rely on this clock to work. TAS6424E device doesn't have internal PLL to generate Main frequency, so the MCLK is essential.

Hi Shadow,

I can see PLLs in the Datasheet block diagram. Is this another use?

Miyaoka-san,

The device does not have a PLL to generate the MCLK from the SCLK. The PL referenced in the block diagram is not discussed in the datasheet, so it is not important to the external operation of the device.

The design team is out on Holiday. Please wait for their return.
