Hi,
The TINA models for the ADS62P49 and similar ADCs only model the input pins for the sample clock and the analog input pins. We do not include TINA models of the outputs of the ADCs. For that the IBIS models are on the TI web for the different ADCs. We do not have models for a complete behavioural model of the ADC from input to output either.
The TINA models would just let you model your input circuit from whatever your source signal is and your input circuitry up to and including the input pins of the ADC, and you would probe the waveforms at whatever points in that simulation that you would want to look at.
