LTM9011-14 input matching filter calculations

Question

Hello, 
 To calculate an input matching filter for LTM9011-14 I'm looking to one or several following options: 
 1) a model of analogue input for that ADC (in the format of NI AWR or any similar) 
 2) S-parameters of the analogue input for that ADC (in the format of Touchstone or any similar) 
 3) Application Note with calculation methods of the matching filter for that ADC. 
 
 Could you please help with obtaining the information? 
 Best Regards, 
 Evgeny Potemkin

We do not recommend using a conjugate match into the ADC, we recommend using an external 50ohm termination and then match to that. The ADC input is a complex impedance that changes over sample rate and input frequency, so doing a conjugate match won't improve the performance.)
