Just a confirmation, dose the status pins, No55 and 56, get high in status of PLL locked?
The status pins for indicating PLL lock, pins 55, 56 on the AD9528 are active high.
hey,sorry to disturb you.I met a problem when I want to configure registers of ad9528 by using the SPI interface of ad9528. As it said in datasheet,the status need to be both low. But the status pins, No55 and 56,are both high. I tried to reset the ad9528,but it doesn't work.Do you know how to change the status? Please.
