The ADX125M12B40G is a Continuous Time (CT) ΔΣ Analog to Digital Converter (ADC) with built-in Anti- Aliasing Filters (AAF) and digital Decimation Filters.
It applies oversampling and captures the differential analog input signal with a 5 GSPS sampling clock, at the easy to drive continuous time analog input.
The CT ΔΣ Modulator loop includes inherent Anti- Aliasing Filter. This significantly reduces analog filter requirements compared to Nyquist ADCs. A robust multi-bit CT ΔΣ architecture ensures low sensitivity to clock jitter.
The ADX125M12B40G contains programmable digital decimation filters. These can be used to reduce data- rate and ensure compliance with the system requirements. The possible access to very high sample- rates, guarantees for excellent timing accuracy.
