CLOCKING THE ADAV4601 USING THE 96-WAY CONNECTOR (MCLK)
b) To clock the ADAV4601 using the MCLK from the 96-way connector, jumper 12 (J12) must be set to position 1-4.
Data from the 96-way connector in this mode can be synchronous or asynchronous, if there is data is from the
SPDIF connector this is asynchronous and can be handled using the SRC1. The appropriate register writes must be
performed to power up and enable the SRCs so as to ensure the correct operation of the device.

Figure 4. Clocking using the 96-way connector (MCLK)
Once the board has been set up to use the 96-way connector the appropriate clock frequency must be
programmed in the ADAV4601. This can be done by writing directly to the initialisation register in the ADAV4601
using SigmaStudio, please refer to the Appendix A – Detailed Register Descriptionsfor more details on register
settings.
