(1) This parameter is specified by design and/or characterization and is not tested in production.
(2) The -3dB point is the traditional Full-Power Bandwidth (FPBW) specification. Although the insertion loss is approximately half at this
frequency, the dynamic performance of the ADC does not necessarily begin to degrade to a level below which it may be effectively used
in an application. The ADC may be used at input frequencies above the -3dB FPBW point, for example for the ADC12D1000RF, into the
5th Nyquist zone. Depending on system requirements, it is only necessary to compensate for the insertion loss.
