Operating the AD9174 using SPI

Thread Summary

The user is trying to generate frequencies on the AD9174 board using the P3 SPI pins with the onboard HMC7044 as the clock source. The support engineer provided a sample macro sequence for configuring the AD9174 and HMC7044, using the onboard 122.88 MHz oscillator to clock the HMC7044, which then clocks the AD9174 DAC. The user is advised to check related threads for additional context.
