FPBW of ADC12D1800

Other Parts Discussed in Thread: ADC12D1800

Hello,

The datasheet of ADC12D1800 states that the FPBW is 2.8 GHz for Non-DES Mode (see 1.1 on page 1 and 4.6 on page 17). Is this refer to undersampling, since the sample frequency is 1.8 GSPS?

Best regards,

Mark,

I'm moving this post to the High Speed Data Converters Forum where the ADC12D1800 is supported. I'm sure that you'll find an answer here.

Hi Mark

Yes, in non-DES mode, with a maximum possible sample rate of 1.8 GSPS, the FPBW frequency of 2.8 GHz implies an undersampling application. Sampling signals in the 2nd and 3rd Nyquist zones is easily supported in non-DES mode.
