#ad9528#ad9371 When I power up the ad9528,I find the pin status0 and status1 are both 3.3V,but the datasheet of ad9528 has no reference about it.I tried to reset the ad9528,but it doesn't work.
Datasheet explains the purpose of status0 and status1 pin it is used to indicate status of internal signals.
Refer below sections in datasheet
SPI/I2C PORT SELECTION
STATUS CONTROL (REGISTER 0x0505 TO REGISTER 0x0507)
If you are using AD9371 EVB then this pin is used to output presence of REFA on status0 and PLL1 and PLL2 locked on status1 once you power on and configure this will show high.
You tagged the AD9371 in your question. Are you using the AD9371 evaluation platform or the AD9528 evaluation board?
