I have a question for internal circuit of AD9239 SDO pin.
When bit7 of Addr 0x00 is cleared, SDO pin should go inactive.
In the SDO inactive situation, I think that the 345 ohm pull down register ( in Figure.44) is disconnected from the SDO pin,
Is this correct?
Also why 345 ohm register should be there?
I think the register is heavy load as a logic circuit...
