How to configure 4x interpolation mode in AD9144?

Question asked by rkumar on Jun 27, 2018

Hello Everyone, 

 

I'm trying to configure 4x interpolation mode for AD9144 in the AD-FMCDAQ2-EBZ board connected to KCU105. I did register setting ad9144_spi_write(dev, 0x112, 0x03) through Xilinx SDK project but with this configuration, I don't see any output on DAC. It works fine with bypass mode ad9144_spi_write(dev, 0x112, 0x00). 

 

Please help me with the required settings to achieve 4x interpolation. Any reference design or example would be great help. 

 

Thanks & Regards,

Rakesh
