I am trying to figure out maximum data clocking speeds for the dac3484 and limits on maximum instantaneous bandwidth. The datasheet mentions fdata is 312.5 Msps max, and max interleaved data rate is 1.25Gsps. Does that mean I can clock each of the I and Q channels at 312.5 Msps ? So in terms of maximum instantaneous bandwidth at baseband, we can synthesize 125MHz bandwidth single-sided or 250MHz double-sided (considering 40% of max sampling rate) ?
Also the complex modulator carrier generated from the NCO can be placed anywhere from 0 to 625MHz (when clocked at 1.25 GHz) or there are limits ?
Thanks , AB
