Clocking The Adav4601 Using The 96-Way Connector (Bclk1) - Analog Devices ADAV4601 System Design Document

CLOCKING THE ADAV4601 USING THE 96-WAY CONNECTOR (BCLK1)

c) To clock the ADAV4601 using the BCLK1 from the 96 way connector, jumper 12 (J12) must be set to position 2-4.
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.

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 initialization register in the ADAV4601
using SigmaStudio, please refer to the Appendix A – Detailed Register Descriptions for more details on register
settings.
