I am using an AD9609 EVAL board, I trying to force a 1V DC at the Input and I observed the BIt 9 and Bit 4 on the Oscilloscope and What I get is fluctuating square pulses of 1V Amplitude. this prevails when I don't give an input also.
I am trying to operate it in Standalone mode the settings are as follows
1. J203- Pin 1 and 2 Connected.
2. J302-No Jumpers in PIN1,2,3,7,8,9. Jumpers in Pin 4 and 5.
3. No Jumper in J202.
4. J201- Jumper in Pin 2 and 3.
5. J605 - Jumper in Pin 1 and 2.
6. J603 -No jumper in J603
Is there Anything that I have missed out.

Thanks for the quick response, I have resolved the issue. The issue was related to the ground of the board and the ground of the probe used for probing(both were at different grounds).
