AD9514 synchronization

I feed AD9514 CLK input from AD9517 output. SYNCB pin of AD9514 is tied with CSB pin of AD9517. After AD9517 callibration finish I read state of AD9517 register once more to synchronize AD9514 outputs, but result is sporadic. What may be a reason of this? SPI CLK frequency is 1.5MHz, CLK signal from AD9517 to AD9514 CLK input is100MHz.
