Hi Ahmet,
Try removing or lowering the value of the 100ohm series resistors.
Also, check the FPGA termination or internals, this interface seems to be current starved as even the edges shown in your oscope plot above are very slow.

Rob

Part Number: ADS5500 Hi,
I am using ADS5500 14 bit ADC. The datasheet of ADC is that has provided straight binary format and 2's complement format. I am using straight binary format. It is a 14 bit ADC. Then what is the fixed point type such as Qm.n format…
Other Parts Discussed in Thread: THS4500 , ADS5500 , LMH6553 , ADS5500-EP Hi,
We are driving ADS5500 using ADC driver THS4500. The Driver operates with +/-5V supply. This is higher than the rated ADC analog input voltage.
Can you suggest the suitable input…
Part Number: ADS5500 Hi,
I'm using an ADS5500 ADC with an FPGA to capture a signal with high temporal resolution.
The idea is to wait for a trigger, and when it is detected start capturing the signal, with an 8ns sampling interval (at 125 MHz, the…
Part Number: ADS5560 Other Parts Discussed in Thread: LMH6552 , THS4509 , ADS5500
First of all, as far as I saw in the data sheet, I saw that the ads5560 works with external 1.5V. However, I could not find the 1.5V reference IC anywhere. Secondly, In page…
Other Parts Discussed in Thread: ADS5500 I need some help understanding the ADS5500 datasheet.
What I would like to know is the Clock Frequency expected at the CLKP and CLKM pins, and the relationship between this frequency and the actual ADC sampling…
Part Number: THS4509 Other Parts Discussed in Thread: ADS52J90 , ADS5500 Hi TI,
I want to use THS4509 as my ADC input driver.
I find one example from the EVM design of "ADS52J90"(website: ADS52J90EVM Evaluation board | TI.com ). But this ADC chip…
Other Parts Discussed in Thread: ADS5500 I am using ADS5500 14-bit parallel configuration adc in my board interfaced to virtex-4 FPGA,The pin no 40 (DFS) of ADS5500 decides the output format whether straight binary or 2's complement .so in design it is…
Other Parts Discussed in Thread: ADS5500 , ADS42JB69 , ADS42LB69 If I have two ADS5500 digitizers with DLL enabled both running off a common clock and measuring the same input signal will the relative phase of the two digital outputs have a fixed relationship…
