Master Mode
The DAC can be configured for master mode operation using Register 10: MASTER MODE AND SYNC CONFIGURATION.
Register 1: Input selections (0x01) input_select must also be set to either DSD or Serial mode. Auto Select will not work correctly in master mode.
DATA_CLK frequency can be configured using one of the following methods:
1. Set the desired master_div in Register 10: MASTER MODE AND SYNC CONFIGURATION.
OR
2. Use NCO mode to set CLK/FSR ratio with Register 34-37: Programmable NCO (0x22 – 0x25). When NCO mode is enabled it has
precedence and the master_div setting will be ignored.
An available GPIO pin can be configured to output CLK using Register 8: GPIO1-2 CONFIGURATION. GPIO1 is recommended for this purpose
since GPIO2 is used to control Low Power Bypass mode.
Contact your local FAE for DoP master mode support.
