Hi,

My customer want to use internal PLL of AD9122.

The conditions of AD9122 is shown below.

  - Ref clock & Data rate: 150MHz

  - DAC clock : 600MHz

  - SPI register : 0x0D ------ 0xD5 / 0x0A ------ 0xCF / 0x0A ------- 0xA0 / the others ------ default value

When she read the register 0x0E [7], the value is '0'.

 

Plese help what is wrong?
