Can you clarify what this means? Go to Support forums. Ask a new question Ask a new question Cancel. Jan 19, 4: When the clock is not driven from FPGA, the offset drops down to zero. Best regards, Jim B. What is the vaule of the input impedance of the chip?

We are using it for sampling an input video signal fed from a Function Generator with 50ohm output impedance at 40MSPS. Video input to AD 2. To find the root cause of this problem, we tried isolating the analog input using the RF switch in between. Your reference range is roughly 0V to 3. I’m assuming the 1. Jan 5, 8: Since we had a comparator MAX also in the path, we suspected the comparator to introduce this DC level.

Yes, the signal should be connected to the analog input. From the datasheet of the TLC In reply to Avinash Mohan:. At pin 5 of U12, the input swings between 10mV and 3. Ask a related question What is a related question? Regarding your divider, can you tell me your expected analog input voltage range? For your 5V reference, the signal should be centered at 2. Example captured data could be helpful as well.

Mentions Tags More Cancel. I think you need to simulate your input circuit to see the response that it is providing. Since yesterday, when we are feeding an input sinusoidal signal swinging between 0 to 3. Output of analog switch in AC path 4. If you have a related question, please click the ” Ask a related question ” button in the top right corner. I would expect the input impedance at DC to be greater than 10 kOhm.

Followed is the schematic: Is it possible that the MSB has been dropped or is being interpreted correctly?
