General Description:
XtremeDSP Development Kit - Where can I find information on the analogue front end on the XtremeDSP Development Kit?
1. Full Scale Range on the input MCX connector
The full scale input range is -1/+1Vpp.
2. Input impedance
The analogue input impedance is matched at 50ohm.
3. Frequency Range
The analogue input frequency range is dc to 36MHz.
4. Is there any strapping or configuration in the path from the input connector to the ADC?
From the connector the analogue input is passed to the ADC via a differential amplifier, AD8131, which converts the single-ended analogue input to differential for input to the ADC. The amplifier has a unity gain. An outline of the analogue input circuitry is outlined in the analogue front end application note.
You can access the application note from the Nallatech website.
