    Thread Summary
    
                The user is verifying the configuration of an AD9838 with a 10 MHz MCLK. The final answer confirms that the AD9838 has no SDO pin for reading back registers, suggests enabling the SIGN BIT OUT for a basic proof of life, and recommends using the No-OS driver from the provided GitHub repository for more advanced configuration.
