I designed a new board with the ad9361.i have a problem in the hardware setup phase.my board looks like to AD-FMCOMMS3-EBZ board.when i connect AD-FMCOMMS3-EBZ to power supply.It takes a little current from the source.
but when i connect my board to power supply it does not take any current from the source
I checked the 1.3 volt voltage below the ad9361 pins and other voltage pins,that's all right
i tested my board with vc707 eval board.but unfortunately it does not work.
My board has a few differences with AD-FMCOMMS3-EBZ
1- I2C EEPROM (M24C02-WDW6TP) is DNP(not populated by default)
2- I2C ADC(AD7291BCPZ) is DNP(not populated by default)
3- I used 3.3v oscillator crystal as input clock(XTALN)
Are these E2PROM,I2C ADC is effective?
Is the 3.3-volt oscillator effective?Does 3.3v oscillator crystal damage the ad9361?
