LVTTL to NIM Translator with AD8009

Hello,

I do agree with KirV that what you seen is an overshoot.

I have tried your circuit only that I have reduced the resistor values by factor of 4.

I only retain the two 100 ohms and the 50 ohms near the output.

I were able to reduce the propagation delay from ~600pS to ~190pS.

Also, I have tried to simplify your circuit.

The 1st stage is inverter/attenuator and the 2nd stage is inverter/buffer.

I used divider instead and feed into the buffer.

I were able to obtain ~135pS prop delay.

Hope this helps.

Dear Fdelaram

Thank you so much for your help, the improvement in delay is huge and that´s wath worried me the most!

Best regards

Dennis
