Part Number: ADS6445-EP
Do we have the S parameters for ADS6445MRGCTEP?Thank you in advance for your help.
I do not think so but we are looking into this.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

We do not have the S-parameters for this part.

Hi Yusuf,Thanks for your support of Carlo's inquiry.We have an additional question from the customer that Carlo is supporting below:In the datasheet of the ADS6445MRGCTEP, frequency characteristics of input impedance are available (in page 37). From these plots, it is understood that the input impedance of the device converges to infinity for frequency range below 5 MHz. In the same datasheet, the drive circuit of the device is also available (Figure 50 in page 38).The question is: Is the device can be derived with this circuitry if the source network has 50-ohm characteristic impedance?Thanks!Jonathan
In reply to Jonathan Geronga:
Below 100MHz The 50ohm source sees a close-to 50 ohm impedance looking into the 1:1 transformer. Therefore, yes you can use the drive circuit found on page 38 so long as your input frequency is below 100MHz.
According to your answer above, I want to learn further information about the product.
I'm using driving circuit in page 38, as you suggest. When placing the product on PCB, I draw the path before the transformer (source side) with 50-ohm single mode. After the transformer (ADC side), patch has 50-ohm differential mode impedance. Are these impedance values of the paths with their mode (single or differential) correct?
Thank you for your time you spent and cooperation.
In reply to Busra Timur Ustundag:
Your approach is correct. The impedance will be 50 ohms single ended looking into the transformer from the input side and 50 ohms differential between the transformer and the device.
Thank you for your quick response. It helps so much. Moreover, I suppose that you do not have s parameters of the product. Am I right?
Unfortunately we do not.
